Horse float parts guide: what to check and repair

Every horse float shares the same critical parts to inspect: floor, ramp hardware, chassis, suspension, brakes, internal fittings and electrics. Of those, floor waterproofing and the removal of manure and urine after every trip is the single routine that prevents most premature failures. Pony Club Australia’s welfare guidance is direct on this point: urine and manure are highly corrosive and will shorten the life of seals, floors and fasteners far faster than normal wear.

Start here before anything else:

Lift the rubber mats and press the plywood floor with your hand. Soft or spongy spots mean moisture has penetrated.
Check ramp hinges and gas struts for corrosion, binding or uneven resistance.
Inspect chassis rails and welds for cracks, distortion or surface rust that has gone through to bare metal.
Test all lights, the trailer plug and electric brakes before every trip.
Check tyre pressure and wheel nut torque, especially after the first loaded trip on a new or recently serviced float.

Key takeaways

Keeping a horse float serviceable comes down to consistent attention to the floor, ramp hardware, chassis and brakes, with organic waste removal after every trip as the single highest-impact habit.

What does a horse float parts guide cover for flooring materials?

The floor is the most maintenance-intensive part of any float, and the material choice determines how much work you will do over the float’s life.

Plywood thickness and type

Ply Online’s guide to horse float repairs recommends 18–25mm plywood for floors, with 9–15mm for dividers and internal walls. The thicker end of that floor range suits larger breeds and heavier loads; 18mm is workable for a standard two-horse float carrying average-sized horses. For walls and dividers, 12mm is a practical middle ground that balances weight and rigidity.

Marine-grade plywood or Australian Form Ply is the right choice for any moisture-prone area. Standard structural ply absorbs water at the edges and delaminates within a few seasons in Australian conditions, particularly in coastal or high-humidity regions. Aluminium flooring avoids the rot problem entirely and saves weight, but it costs more upfront and can be slippery without the right matting. For most owners, quality sealed plywood with good rubber matting is the practical choice.

Rubber matting and sealing

Rubber matting at 10–12mm thickness is the standard for slip resistance and moisture protection. Thinner mats compress under a horse’s weight and lose their cushioning; anything over 12mm adds unnecessary weight. A separate mat that lifts out for cleaning is far better than a bonded mat, because you can inspect the plywood underneath after every trip.

Edge sealing is where most plywood floors fail. Hosing the float without resealing cut edges drives moisture straight into the ply core. Seal every cut edge with a quality exterior-grade sealant before installation, and reseal annually or whenever you notice the coating lifting.

Material	Recommended thickness	Pros	Cons
Marine-grade plywood	18–25mm (floor), 9–15mm (walls)	Moisture-resistant, workable, cost-effective	Needs regular edge sealing
Australian Form Ply	18–25mm (floor)	Durable, suited to Australian humidity	Heavier than standard ply
Aluminium sheet	2–3mm structural grade	Corrosion-resistant, lightweight	Higher cost, slippery without matting
Rubber matting	10–12mm	Slip resistance, moisture barrier, cushioning	Hides floor damage if not lifted regularly

Installation checklist:

Sand all plywood edges smooth before sealing.
Apply two coats of exterior sealant to all cut edges and let each coat cure fully.
Fasten boards with corrosion-resistant screws, countersunk flush.
Lay rubber mats loose (not bonded) so they can be removed for inspection.
Check for gaps between boards where urine can pool.

Pro Tip: Run your hand along floor edges after hosing. If you feel any softness or the sealant is peeling, reseal immediately. A $20 tube of sealant applied early saves a full floor replacement.

How do ramp hardware and gas struts work, and how do you replace them?

The ramp is the part of a float that gets the most mechanical stress and the least attention. Hinges, coil springs and gas struts all work together to control ramp weight; when one fails, the others compensate until they fail too.

Identifying ramp hardware

Common ramp components include:

Heavy-duty hinges: typically 304 or 316 stainless steel for corrosion resistance; check for cracked welds at the mounting plate.
Coil springs: assist ramp lift; Australian-made tailgate ramp coil springs (such as 19mm tempered steel, available in left and right configurations from local suppliers) are treated for rust protection and suit Australian conditions.
Gas struts: provide controlled resistance on opening and closing. Struts Australia’s horse float catalogue lists part numbers, stroke lengths and force ratings. A typical ramp strut might be labelled with its stroke (e.g. 300mm) and force (e.g. 500N); matching both figures to the original is critical for safe ramp balance.
Slam locks and latches: check for free movement and positive engagement; a latch that needs force to close is already failing.

Choosing and replacing a gas strut

Match the replacement strut by three figures: stroke length (the distance the rod travels), force rating (in Newtons) and mounting thread or eye type. A strut with the right stroke but wrong force will either slam the ramp or make it too heavy to lift. Struts Australia’s catalogue organises by these parameters, which makes cross-referencing straightforward.

Safety first: gas struts and coil springs store significant mechanical energy. Never remove a ramp strut or spring without first supporting the ramp on a solid prop. A ramp falling unexpectedly can cause serious injury.

Pre-trip ramp checklist:

Lift and lower the ramp twice; it should move smoothly with consistent resistance.
Check hinge pins for play or corrosion.
Inspect strut rods for scoring or oil weeping (signs the seal is failing).
Test latch engagement; the ramp must lock positively with no rattle.
Look for cracks at the ramp frame corners where stress concentrates.

Pro Tip: Label the old strut with a marker before removing it. Note the stroke, force rating and mounting type. Take it to the supplier as a physical reference — part numbers on worn struts are often unreadable.

What should you inspect on the chassis, suspension and brakes?

Structural failures rarely happen without warning. The signs are there if you know where to look.

Chassis and frame materials

Aluminium frames resist corrosion better than steel and are lighter, but they cannot be welded with standard MIG equipment. Steel frames are heavier and rust, but repairs are more accessible. Hoofbeats Magazine’s float selection guide notes that structural failures are more often the result of poor welding or faulty joint integration than the metal type itself. Moisture intrusion at joints and seams is the primary threat to long-term structural integrity, regardless of material.

Inspect welds at chassis rail junctions, crossmembers and suspension mounting points. A crack in the paint along a weld line is not cosmetic; it is a stress indicator. Treat any weld crack as a reason to stop using the float until a qualified welder assesses it.

Suspension components

Standard horse float suspension uses leaf springs, shackles and U-bolts, with some models using roller rocker systems. Check U-bolt torque after the first 1,000 km of use; new U-bolts bed in and can loosen during the break-in period. Axle hangers and spring eyes are common corrosion points; grease them at every service.

Braking systems

VSB1 Revision 6 sets the regulatory framework for trailer construction and inspection, including acceptability criteria for rusted structural members. Electric brakes are required on trailers above certain mass thresholds; check your state’s specific requirements. A basic brake check covers: brake controller response, brake magnet condition (look for scoring or glazing), and whether the trailer pulls straight under braking.

Chassis and suspension inspection checklist:

Check all chassis rails for cracks, distortion or through-rust.
Inspect suspension mounts, U-bolts and axle hangers for corrosion and torque.
Look for cracked or sagging leaf springs.
Test shock absorbers by pushing down on each corner; the float should rebound once and stop.
Check tyre pressure and tread depth; uneven wear signals a suspension or alignment problem.
Verify electric brake function before every trip.

Statistic callout: Professional mechanics recommend an annual full service covering brakes, bearings, chassis and suspension as the single most effective preventative measure for horse floats. Checking wheel nut torque after the first two hours of use and again at the 1,000 km mark is a known risk window for trailer fastenings.

Pro Tip: After a trip, touch the hub caps. If they are hot, stop and investigate immediately. Bearing heat is an early warning that a bearing is failing; catching it early is the difference between a bearing replacement and a wheel-off incident.

What internal fittings and fasteners should you check regularly?

Internal fittings take a beating from horses shifting weight, pawing and leaning. They also sit in a corrosive environment of urine, manure and moisture.

Common internal parts

Chest bars and partitions: typically 12mm plywood with aluminium or steel framing; check for cracking at mounting points and delamination at edges.
Breaching gates: must latch positively and swing freely; a stiff gate is a safety risk during unloading.
Tie points: inspect welds and bolts for corrosion; a tie point that pulls out under load is a serious injury risk.
Padding: closed-cell foam covered with a wipe-clean vinyl is the practical standard; check for tears that allow moisture into the foam core.
Windows and vents: check latches, hinges and rubber seals; a leaking window seal drives moisture into the wall cavity.

Fasteners and fixings

Use 316 stainless steel bolts and screws in any area exposed to urine or moisture. Standard zinc-plated fasteners corrode within a season in a horse float environment. Rivets are acceptable for panel attachment but should be stainless or aluminium; steel rivets rust and stain the surrounding material. Check all fasteners for loosening every three months; vibration works screws and bolts loose faster than most owners expect.

Quick-release mechanisms on tie points and partitions need to work with one hand under pressure. Test them with gloves on; if you need two hands or significant force, the mechanism needs adjustment or replacement.

Daily visual checks for internal fittings:

Confirm all partition latches engage positively.
Check tie points for movement or corrosion at the base.
Inspect padding for tears or compression damage.
Look for loose screws or rivets on panel edges.
Test quick-release mechanisms before loading.

Pro Tip: Wipe down padding with a diluted disinfectant after each trip. Urine soaks into tears in the vinyl cover and degrades the foam beneath; once the foam is saturated, the padding needs full replacement.

How do you troubleshoot trailer electrics and lights?

Electrical faults are the most common reason a horse float fails a roadworthiness check, and most are preventable with basic maintenance.

Major electrical components

A standard horse float electrical system includes a 7-pin or 12-pin trailer plug, a wiring loom running to tail lights, brake lights, indicators, and number plate lights, electric brake wiring, and sometimes auxiliary circuits for water pumps, interior lighting or a battery system. Isolator switches protect auxiliary circuits and the battery from drain.

Common faults and quick checks

Most electrical faults trace back to three causes: corroded connectors, a blown fuse or a damaged loom section. Start with the trailer plug; green or white corrosion on the pins is the most common fault and the easiest to fix. Clean pins with electrical contact cleaner and a small wire brush, then apply dielectric grease to prevent recurrence.

If a light circuit is dead, check the fuse before tracing the loom. A fuse that blows again immediately after replacement means there is a short in the circuit; that requires a qualified auto-electrician.

Safety note: Always disconnect the battery or unplug the trailer from the tow vehicle before working on the wiring loom. A 12V system will not electrocute you, but a short circuit can cause a fire or damage the brake controller in the tow vehicle.

Pre-trip electrical checklist:

Plug in and walk around the trailer; check tail lights, brake lights, indicators and number plate light.
Activate the brake controller and confirm brake magnets engage (you will feel a slight drag if you push the trailer by hand).
Check the trailer plug pins for corrosion or bent contacts.
Inspect the loom where it passes through grommets or along the chassis for chafing.
Confirm auxiliary circuits (pump, interior lights) function if fitted.

Compliant lighting is a legal requirement under Australian road rules. A float with a non-functioning brake light or indicator is unroadworthy and creates liability in the event of an accident.

What does a routine horse float maintenance schedule look like?

A maintenance schedule is only useful if it is specific enough to follow. Here is a practical breakdown by frequency.

Task	Frequency	Who
Check lights, tyres, wheel nuts, latches, mat condition	Before every trip	Owner
Remove manure and urine; hose and dry float	After every trip	Owner
Inspect floor edge seals, grease suspension points, check electrical connectors	Monthly	Owner
Check battery health and charge if auxiliary fitted	Monthly	Owner
Full brake inspection, bearing check, chassis weld inspection	Annually	Qualified mechanic
Suspension service: leaf springs, shackles, shock absorbers	Annually	Qualified mechanic
Re-torque U-bolts after first 1,000 km	Once (break-in period)	Owner or mechanic

Professional mechanics recommend an annual full service covering brakes, bearings, chassis and suspension as the single most important preventative measure. Most owners underestimate how much a float moves and vibrates under load; components that feel solid in the driveway can work loose within a few hundred kilometres.

Pro Tip: Set a calendar reminder for your annual service at the same time each year, tied to a known event like the start of the competition season. A float that sits unused over winter still needs a full service before it goes back on the road.

How do you fix common horse float problems yourself?

Most owners can handle a handful of repairs safely. Knowing the boundary between DIY and professional work is as important as the repair itself.

1. Replace a rubber mat

Tools: Stanley knife, straight edge, measuring tape.
Steps: Remove the old mat, clean the floor surface and inspect the plywood for soft spots. Cut the new mat to size with a straight edge. Lay it loose; do not bond it. Check that edges sit flat with no curl that could trip a horse.
Confirm success: Mat lies flat, no gaps at edges, plywood beneath is dry and firm.

2. Patch a small soft spot in plywood

Tools: Drill, jigsaw, chisel, exterior sealant, replacement ply, corrosion-resistant screws.
Steps: Remove the mat and mark the damaged area. Cut out the soft section with a jigsaw, going back to solid timber. Cut a replacement piece of the same thickness. Seal all edges of the new piece before fitting. Screw into solid timber on all sides, countersink the heads, and fill with sealant.
Confirm success: New section is firm underfoot, all edges sealed, no movement when loaded.

3. Swap a gas strut

Tools: Prop for the ramp, spanners or sockets to match the mounting hardware.
Steps: Prop the ramp open on a solid support. Unclip or unbolt the old strut at both ends, noting the orientation. Fit the new strut in the same orientation. Remove the prop and test ramp movement.
Confirm success: Ramp opens and closes smoothly with consistent resistance; latch engages without forcing.

4. Tighten or replace U-bolts

Tools: Torque wrench, correct socket size.
Steps: Jack the trailer safely and support it on stands. Remove the wheel if necessary for access. Torque U-bolts to the manufacturer’s specification. If a U-bolt is cracked or corroded through, replace it; do not retorque a damaged fastener.
Confirm success: No movement at the axle mount; U-bolt threads are clean and fully engaged.

5. Patch surface corrosion on steel chassis

Tools: Angle grinder with flap disc, rust converter, zinc primer, topcoat paint.
Steps: Grind back to bare metal. Apply rust converter to any remaining rust. Prime with zinc-rich primer and finish with a compatible topcoat. If the corrosion has gone through the metal wall thickness, stop and get a welder to assess it.
Confirm success: No remaining rust scale, paint adheres cleanly, metal is solid when tapped.

Where can you buy horse float parts in Australia?

Sourcing the right part matters as much as fitting it correctly. Australian-made components often suit local conditions better than imported equivalents, particularly for springs and treated steel hardware.

Specialist suppliers by part category:

Gas struts: Struts Australia catalogues horse float-specific struts by stroke and force rating; ordering by part number is straightforward.
Coil springs: local Australian manufacturers produce tailgate ramp coil springs in tempered steel, treated for rust, in left and right configurations. Sunrise International is one example of a local supplier stocking 19mm Australian-made ramp springs.
Rubber matting: specialist float suppliers and agricultural rubber suppliers stock 10–12mm matting; Regencyfloats’s rubber flooring guide covers thickness and installation options.
Marine plywood and Form Ply: timber merchants and specialist ply suppliers such as Ply Online stock marine-grade and Australian Form Ply in the recommended thicknesses.
Fasteners: Trailer Spare Parts stocks heavy-duty horse float-specific fasteners and latch hardware with delivery across Australia.
Bearings and brake parts: trailer spare parts specialists and bearing suppliers (such as CBC or Bearing Warehouse) carry the common sizes used on Australian horse float axles.

Buying checklist before ordering any part:

Confirm the exact dimensions (stroke, diameter, thread type for struts; thickness and grade for ply).
Check the load or force rating matches the original specification.
Verify corrosion resistance rating for the environment (marine-grade for coastal areas).
Confirm the supplier’s return policy in case of fitment mismatch.
Ask whether the part is Australian-made or imported; for springs and structural hardware, local tempering standards often suit Australian temperature ranges better.

Pro Tip: Take photos of the old part before removal, including any stamped part numbers and the mounting configuration. A clear photo saves significant back-and-forth with suppliers and reduces the risk of ordering the wrong item.

FAQ

What plywood thickness is best for a horse float floor?

Use plywood of appropriate thickness for the floor, with marine-grade or Australian Form Ply preferred for moisture resistance. Thinner ply compresses under load and degrades faster, particularly in humid Australian conditions.

How often should a horse float be professionally serviced?

An annual full service is the industry standard, covering brakes, bearings, chassis welds and suspension. Wheel nut torque should also be checked after the first two hours of use and again at the 1,000 km break-in mark.

How do I match a replacement gas strut for my ramp?

Match by three figures: stroke length, force rating (in Newtons) and mounting type. The Struts Australia catalogue lists horse float-specific struts by these parameters, making cross-referencing straightforward.

When should I stop using my float and call a professional?

Stop immediately if you find a cracked chassis rail, a broken structural weld, brake failure or a ramp that will not latch securely. These faults are beyond DIY repair and create serious safety risks on the road.

What is the best way to prevent floor rot in a horse float?

Remove manure and urine after every trip, lift rubber mats to allow the floor to dry, and reseal all plywood edges annually. Organic waste is highly corrosive and accelerates rot far faster than normal moisture exposure.
