Below is a short list of operational procedures and helpful hints to ensure your

WALKING FLOOR

system provides years of good service.
1. The hydraulic pump and PTO system requires hydraulic pressure of 3000 PSI
with a minimum of 30 gallons of oil per minute for proper operation.
2. The PTO/Pump system requires a pressure relief valve set at 2800 PSI.
3. End Dump truck PTO systems set at a maximum 2200 PSI hydraulic pressure
will not operate a WALKING FLOOR system properly and could cause serious
damage to the system.
4. The WALKING FLOOR system requires a minimum 40 gallon oil reservoir to
ensure oil does not overheat during unloading and result in heat damage.
5. Properly installed, smaller oil reservoirs with coolers can be used.
6. A trailer equipped with a standard KEITH WALKING FLOOR drive is capable of
unloading approximately 32 tons of material.
7. A trailer equipped with a heavy-duty KEITH WALKING FLOOR drive is capable
of unloading up to 52 tons.
8. A trailer equipped with a KEITH WALKING FLOOR drive is capable of unloading
most materials in 4 minutes or less, if the PTO/Pump is set up properly.
9. Unloading speed is a function of oil flow. With an oil flow of 30 GPM, the
average unloading time is 6 to 7 minutes for a 45 ft/13.5 m trailer.
10. All WALKING FLOOR systems are designed for two way operation- loading or
unloading material. A “Control Valve” controls the forward or reverse floor
movement.
11. A partially opened or closed on/off Ball Valve will create heat damage and result
in slower unload speeds. Open and close the on/off valve completely.
12. Heat damage will void the warranty on hydraulic components.
13. Always make sure back doors are open before engaging the WALKING FLOOR
system.
14. Never walk on or stand in the way of the material while unloading.
15. Make sure quick couplers are fully connected.
16. Be sure the quick couplers are connected correctly (Pressure to Pressure-Return
to Return).
