How to diagnose a Konecranes CXT hoist that won't lift
If the motor runs but the hook does not move, the hoist brake is stuck engaged. If the motor does not run, read the fault code on the crane controller before anything else.
How to fix excessive hook block swing on a Konecranes CXT hoist
Persistent hook swing after stop is usually worn sheave bearings or a trolley alignment issue. Check sheave bearing play first. If bearings are good, adjust the anti-sway brake ramp in the drive.
How to fix hook drift after stop on a Konecranes CXT hoist
Drift after stop means the hoist brake is not holding. Check the brake air gap and pad thickness. A worn spring or glazed disc cannot hold a load safely.
How to diagnose and fix a limit switch failure on a Konecranes CXT hoist
A limit switch that does not stop the hoist is a safety-critical failure. Lock out the crane immediately. Test the switch contacts with a multimeter and replace if contacts do not close at the correct actuator position.
How to fix jerky travel motion on a Konecranes CXT overhead crane
A rhythmic jerk during travel is almost always a flat spot on one travel wheel. Lock out and rotate each wheel by hand to find the flat spot, then replace the wheel.
How to inspect and replace fraying wire rope on a Konecranes CXT hoist
Remove the rope from service if 6 or more broken wires appear in any rope lay length, or if the rope diameter is reduced by more than 10% from nominal. Do not attempt to repair a damaged wire rope.
