Why does Elliott Digger Derrick Utility Vehicle boom creep back after being extended?
It's normal for the boom on your Elliott Utility Vehicle to creep back slightly after being extended, as hydraulic oil cools and retracts in the telescope cylinder. However, if the creep continues, first check for leaks. Then, clean or replace the holding valve and check its setting. Finally, remove the telescope cylinder, rebuild it, and replace the seals.
What to do if boom tele out, winch up and boom down are not working on Elliott Digger Derrick Utility Vehicle?
If the boom tele out, winch up, and boom down functions are not working on your Elliott Utility Vehicle, and these are the only functions affected, first check if the boom head is two-blocked. Next, verify the load against the Capacity Chart to ensure it's not an overload. Then, consult the LML and Anti-Two Block operator’s manual for troubleshooting this system. Also, inspect the wiring from the system to the solenoid valves and check the valve operation to ensure they are not jammed.
What to do if Elliott Utility Vehicle swing brake does not hold?
If the swing brake on your Elliott Utility Vehicle fails to hold, the brake return springs are likely broken, or the brake discs are worn or damaged. Disassemble the brake and replace any faulty parts.
What to do if Elliott Digger Derrick Utility Vehicle outrigger/stabilizer creeps in under load?
If the outrigger/stabilizer on your Elliott Utility Vehicle creeps in under load, clean the holding valve and check the relief setting. Replace components as required.
