Troubleshooting
A cable carrier that slaps, rattles or ticks is more than annoying: it almost always signals that something is not running cleanly. Noise means play, slapping or friction — and that costs service life. Below are the causes we see most often in the field, in the order you should rule them out.

If a carrier runs unsupported for more than roughly one and a half to two metres, the upper run sags and slaps onto the lower run at every reversal. That is the typical thud-thud sound. The fix is a guide trough in which the upper run glides neatly over the lower run; that calms the motion, often halves the noise and considerably extends service life.
In a worn carrier the pin-and-hole joint has worn out and every link ticks at each change of direction. Dust, chips and wood dust accelerate that process. If the carrier rattles audibly when you bend it by hand, replacement is the only real answer — and then pick an enclosed version if the environment is dirty.
An almost empty section sounds louder than a well-filled one: nothing damps the links. Loose cables sliding back and forth in an over-wide chamber do the same. Distribute the fill with dividers across the width, keep equal weight left and right of the neutral line, and switch to a narrower series if needed.
Above roughly 2 m/s and at high accelerations the whipping effects in the carrier become audible. High dynamics require a guided run and even fill. A light plastic carrier is quieter than steel; if steel is unavoidable, guidance and a damped installation become more important.
If the fixed end sits at the wrong height, the arc does not run round and the carrier ticks against something every stroke. Check that the fixed end and driver bracket are in line, that the trough is not dented and that no cable clamp sits inside the moving zone. This is the cheapest of all causes and at the same time the most common.
A video, dimensions and travel length in the quotation form is enough. On working days you receive a diagnosis with the parts you need within three hours.
