Hoist safety brake: Kept open

02061.00048 Hoist safety brake Kept open

Problem:

This fault was a recurring fault in the fault history log. The fault would clear the active fault log when the crane was in use and only appear when the crane was turned off.  (Switched off from the remote or an Estop command input)

Solution:

Determine if the crane is fitted with optional “SAFETY BRAKE”  If fitted: follow directions in CCS Manual to correct the fault.

If not fitted, check the configuration of the crane and determine if the safety brake option is not active.

If active, De-select the option

and restart the crane.  Fault code with be removed.

Multi-Quip Generator “no start”

Symptom : Generator ran fine when shut down, Went to start the next morning, the fuel pump would prime, engine cranked a few revolutions but engine would not start, subsequent tries would prime fuel pump but no engine start sequence.

 

Fix: Replace ECU fuse -15amp

Procedure:

  1. Remove  2 thumb  screws holding on instrument panel.
  2.  Locate  fuse holder *see attached photo Fuse(original fuse was a 15amp Buss Fuse)
  3. Replace  blown fuse with 15Amp blade fuse- If no fuse is available running the generator in diagnostic mode will bypass this circuit assuming all other parameters are correct.
