Stacker drive wheel drive motor speed significantly reduced or severe overload Cause

The battery voltage is too low or too big pile head contact resistance; between the motor commutator segments coke cause a short circuit between the chip; motor improperly adjusted brakes with brake leaving the motor running; drive head gear boxes and bearings lack of lubrication or chassis card motor armature short circuit; resistance.
Solution: Check the battery terminal voltage Stacker load or cleaning trailer coupling; clean up the commutator; adjust the brake clearance; checking cleaning and re-filling oil, remove Electric Hand Pallet Jacks jamming phenomenon; replace the new motor.Stacker crane lifting weakness or not
Reason: Gear pumps and pump mention excessive wear; improper high-pressure relief valve inside; oil pipeline spill; hydraulic oil temperature over; mast carriage
jamming phenomenon exists; pump motor speed is too low.
Solution: Replace worn or gear pump; readjust; inspection and repair; replace defective hydraulic oil and drum trucks the oil temperature rise causes; Check and adjust; Check the motor and troubleshooting.
piled high door frame automatically tilt difficulties or action not smooth
Cause: The tilt cylinder wall and seals for excessive wear; within the valve stem spring failure; piston rod stuck in the cylinder wall or bent; within the tilt cylinder seals fouling too much or too compressed.
Solution: Replace the O-rings or cylinders; replace qualified spring; replace damaged parts; cleaning adjustments.
