A trailer landing gear is a load-bearing support system that holds a semi-trailer steady when it is uncoupled from the tractor (28T Trailer Landing Gear Semi). For fleet operators in Kenya, choosing the right 28T unit affects safety, downtime and total running cost (28t Trailer Landing Gear Leg). This guide explains what to check before you buy.
What a Trailer Landing Gear Does
The landing gear, also called trailer legs or outriggers, supports the front of a semi-trailer when no tractor is attached (Semi Trailer Landing Gear 80T). It carries the trailer's static load during loading, parking and storage.
A typical set has two legs, an internal screw jack and a gearbox. A hand crank or electric motor drives the screw. The legs raise and lower the trailer deck to match the tractor fifth wheel height.
Load capacity is the key figure. A 28T rating means each set is built for a 28 tonne static support load. Always match the rating to your trailer's front-end weight.
How to Choose a 28t trailer landing gear
Selection starts with the trailer type and the duty cycle. Kenyan fleets often run mixed routes, from the Port of Mombasa corridors to inland depots. The gear must handle repeated coupling and rough yard surfaces.
Consider these factors before ordering:
- Load rating: confirm the 28T capacity suits your trailer's front load.
- Travel length: check the stroke matches your tractor fifth wheel height.
- Drive type: choose manual crank or electric operation.
- Mounting dimensions: verify the bolt pattern and leg spacing.
- Material: carbon steel legs suit heavy-duty use.
For example, the 28t trailer landing gear Semi Trailer Leg 19 in 480mm uses carbon steel and lists a max payload of 80T. However, always treat the rated capacity as the working limit for safe operation.
Manual vs Electric Landing Gear
Manual crank legs are simple and low-maintenance. They suit fleets with trained drivers and predictable schedules.
Electric landing gear reduces driver effort and speeds up coupling. The 28T Electric Landing Gear for Trailer Outrigger is a replacement/repair option for trailers that need powered operation.
Electric units depend on a reliable power supply. Therefore, check battery and wiring condition on your tractor before you specify an electric set.
Specifications That Matter
Buyers should read the product data sheet carefully. The table below compares key attributes across common 28T options.
| Attribute | What to check |
|---|---|
| Load capacity | 28T rated set; confirm front-end weight |
| Max payload | Some units list 80T max payload |
| Material | Carbon steel for heavy-duty legs |
| Travel length | 480 mm (about 19 in) on one model |
| Condition | New replacement parts |
| Purpose | Replacement or repair |
The 28t Trailer Landing Gear Heavy Duty Truck Legs 28 Ton lists dimensions of 300 x 300 x 300 mm. Confirm these figures against your trailer mounting bracket before purchase.
Besides capacity, check the screw and gearbox quality. A worn screw thread causes slipping under load. Inspect the gearbox seals for dust and water resistance, since Kenyan roads can be dusty and wet in the rainy seasons.
Mounting and Fit
Fit is as important as capacity. Measure the existing leg spacing and bolt holes on your trailer. A mismatched bolt pattern means drilling or adapter plates, which adds cost and downtime.
Ask the supplier for a dimension drawing. Compare it with your trailer frame. This step avoids returns and keeps your fleet on the road.
Applications and Market Notes for Kenya
Kenyan logistics operators use semi-trailers for port haulage, fuel transport, container movement and general cargo. Each duty cycle places different demands on the landing gear.
Port and container work involves frequent uncoupling in yards. Heavy-duty carbon steel legs with a 28T rating suit this pattern. Long-haul routes to inland depots need stable legs that resist vibration.
Spare parts availability matters. Therefore, standardise on one landing gear model across your fleet where possible. Common parts simplify repairs and reduce stock-keeping.
Tongtrailer supplies heavy-duty semi-trailer components for export markets. Buyers can request product data and dimension drawings before ordering.
Replacement and Repair Planning
Landing gear is a wear part. Plan replacements before failure, not after. Keep at least one spare set for critical trailers.
The this 28t landing Trailer Support Legs is listed as a new replacement/repair part. The 28T Trailer Landing Gear for Semi Truck Trailer Parts is also offered for replacement and repair use.
Track inspection results per trailer. Replace legs showing bent screws, cracked housings or heavy play. Early replacement protects cargo and reduces roadside delays.
Practical Tips for Fleet Operators
Good maintenance extends landing gear life. Use these habits in daily operations.
- Grease the screw and gearbox at scheduled intervals.
- Crank legs fully up before moving the trailer.
- Keep the landing gear clear of sand and gravel buildup.
- Check bolts and mounting brackets for looseness.
- Train drivers to lower legs evenly on firm ground.
- Store spare gearboxes and cranks for quick repair.
Besides routine checks, review load limits with drivers. Overloading the front end stresses the legs beyond the 28T rating. This shortens service life and raises safety risk.
Therefore, match the landing gear to the trailer's real front load. Use the manufacturer's data, not estimates. Document each trailer's setup so replacements are quick and correct.
Conclusion
Choosing the right trailer landing gear for your Kenyan fleet comes down to capacity, fit and duty cycle. A 28T rated set suits many heavy-duty semi-trailer applications. Confirm dimensions, drive type and material before you order.
Tongtrailer offers several 28T landing gear options for replacement and repair. Review the specifications, compare them with your trailers, and request a quote for your fleet requirements.
FAQ
What does a 28T landing gear rating mean?
It means the landing gear set is rated for a 28 tonne static support load. Match this rating to your trailer's front-end weight.
Can I use 28T landing gear on all semi-trailers?
Not always. Fit depends on mounting dimensions, travel length and front load. Check the data sheet against your trailer frame.
What is the difference between manual and electric landing gear?
Manual gear uses a hand crank. Electric gear uses a powered motor, which reduces driver effort during coupling.
What material are these landing gear legs made of?
One listed model, the 480 mm leg, uses carbon steel. Always confirm material on the product data sheet.
When should I replace trailer landing gear?
Replace legs with bent screws, cracked housings or heavy play. Plan replacement before failure to avoid downtime.
Do you supply landing gear for replacement and repair?
Yes. Several 28T models are listed for replacement and repair use. Request a quote from Tongtrailer for your fleet.
