FAQ

When choosing a trailer, one should ask the following questions:

• with what kind of tractor will the trailer be used (capacity, tractor type)?
• what materials will mainly be transported?
• how long will the distances be?
• what kind of ground will the trailer mainly be used on?
• how will the trailer be loaded?
• what are the maximum lifting heights for existing equipment?
• are there any other special conditions in the environment? If so, what are these (such as the height of the warehouse door through which the trailer must fit, or the height of the ceiling in the room in which the trailer will be used when in a tilted position)?

Depending on the season, the delivery time usually varies between 4-8 weeks, sometimes the product can be received faster. Also, you can always ask our sales manager if there are any products in stock. For a definite answer, contact: sales@palmsetrailer.eu

Here are some useful tips and things to remember about how to do maintenance to a tractor trailer:

• Tractor trailer maintenance works must be carried out regularly to ensure safe and malfunction-free operations in farming and road construction.
• Agricultural tractor trailer maintenance works do not require any special tools. The user can perform most of the operations.
• Remember to use correct tools.
• Attempt to localize the defects as clearly as possible; you should have to avoid opening the system unnecessarily.
• Keep disassembled parts and repair area protected from dirt.
• Keep spare parts in their packages until needed for installation.

During maintenance

• Be sure that the trailer is standing on a flat surface.
• Be sure that the trailer can’t move.
• When lubrication or servicing the trailer, turn off the vehicle engine.
• Be sure that the trailer can’t slip when you using support leg, jack or similar equipment.
• Always use the box support in tipping position when servicing.
• Never attempt to do maintenance works on the hydraulic system before you are sure there is no pressure.
• Do not tighten or repair leaking hydraulic couplings while the system is pressurized.
• Never attempt to localize a leakage from hoses or connections by feeling with hand. The high pressure oil jet can penetrate skin and cause serious burns and damages. High-pressure oil is also highly flammable.
• Avoid getting oil into eyes. Use safety goggles and gloves. If oil has got into eyes flush them with cool water, contact the doctor.
• Protect and inspect cylinder rods of hydraulic drawbar, hydraulic ramps, axle block, steering axle(s), hydraulic supportleg, hydraulic bale holders: 1) 1x a week, add light layer of protective vax; 2) Prior leaving the trailer unused for longer periods of time, afterwards 1x a month, add thicker layer.
• Grease change in hub bearings – needed in every 3000 working hours (or every 50000km travelled).
• Bearing cap check: After the first 200 working hours at full load (or after the first 300 km travelled), afterwards every 1500 hours (or every 25000 km travelled). Make sure the wheel bearings do not rock. This check is performed by lifting the axle with a jack until the wheel is off the ground and rotates freely. Insert a lever between the ground and tyre and force the wheel up to find any gaps.
• Wheel nut check: after first 100 km or 3 workhour check and if necessary retighten wheel nuts. Afterwards check and tighten wheel nuts: 1)After first load; 2)After first 1 000 km; 3)Every 6 months or 25 000 km
• After first 100 km retighten leaf spring restraining nuts with 385 Nm torque. Further on retighten after every 300 km.
• Check tire pressure regularly!
