Felling Trailers manufactures hydraulic dump trailers ranging in capacities from 4,500 – 30,000 lbs. Each trailer has a hydraulic pump system that operates the raising and lowering of the hydraulic cylinder or hoist that raises/lowers the dump box. If your Hydraulic Dump Trailer System is not working properly, we are here to help. We recently talked to our Warranty Coordinator, Scott Brown, to get his expertise on fixing hydraulic dump trailers. Below are some troubleshooting tips for issues that may occur with the regular operation of a hydraulic dump unit.
Trouble Shooting Hydraulic Dump Trailer Systems
My hydraulic dump trailer is leaking fluid, what should I do?
Before inspecting for leaks, make sure that the box is up. Always use the safety lock bar to hold the box up. View the Operating Instruction Felling Hydraulic Dump (PDF).
What is the leak caused by?
Typically any leak is caused by a battery with a low charge. The weight of the box is putting pressure on the system so as the box is lowered, the pump can’t keep up with that pressure due to the low battery. Then it creates excessive pressure causing the oil to blow out of the breather on the tank. We have seen some cases that the breather is plugged with so much dirt that it creates excessive pressure and cracks the tank. It is advised prior to the use of the hydraulic system to look over the unit and ensure it is free of debris and dirt.
I am having issues with keeping the battery charged. What battery chargers do you recommend?
There are some very useful battery chargers that can help. Be aware, however, that to charge your dump trailer system, the tow vehicle has to be running and the headlights need to be turned on. Both examples below can be purchased through Felling Trailer’s Parts & Service Department at 866-335-5464 or email at [email protected].
- Trickle Charger – Trickle chargers are very convenient because they allow you to always start the day with a fully charged battery. Click here for more info on a trickle charger.
- Solar Panel Charger – The solar panel charger is also a great choice. If you don’t use the trailer every day, you can be assured that when you do use it, it will have a fully charged battery. Click here for more info about how the solar panel battery charger works.
How many cycles can an average dump trailer run before the battery is depleted?
If you are doing short runs between cycles – approximately four to five. If you are driving 100 miles between cycles, then you would probably get more, since the additional distance would allow for more charging time for the battery.
The hoist is stuck in the dump position, what should I do?
Looking down on the pump there is a square-shaped coil (down) and a round-shaped coil (up), generally, you can loosen the nut onto each coil and swap them around, which then allows you to lower the box. It is possible to continue to haul with the trailer this way by swapping the coils around until the new one arrives. Note: This is a temporary fix until new parts are received to replace the defective parts and/or pump.
After my unit is fixed, what type of hydraulic fluid should I fill it with?
Fill the tank to approximately half full. The type of hydraulic fluid should be automatic transmission fluid.
