Push/pull monitoring

Cable chain specialist Tsubaki Kabelschlepp has come up with a new push/pull force monitoring unit aimed at ensuring increased reliability and safety for its cable chain in crane and other long travel applications.

The unit is designed to take constant measurements on the drive end connection. This can prevent damage to the overall system and the ensuing costly unexpected downtimes if the cable carrier is blocked by external influence, such as dirt, metal or wood shavings. The system is designed for all industrial areas, but it is particularly suitable for cranes and long travel applications, said Tsubaki Kabelschlepp.


The force limitations of the system (lower and upper limits) can be programmed freely and there is no travel speed limit. The output signal can be used as a PLC input signal, allowing an emergency stop, a slowdown or an acoustic signal to be triggered when the programmed force limits are exceeded.

The system is maintenance free (no battery change) and complies with protection class IP67. The heavy-duty version of the system box is resistant to sea water and is therefore suitable for use in seaports.


The monitoring unit is optionally available with a data memory, allowing users to save and evaluate the development of the forces. The control box is integrated directly into the drive section of the system, ensuring short cable lengths. “It is particularly suitable for cranes in container ports, cement works, steelworks, foundries or waste incineration plants, but also for handling bulk materials such as coal, ore or spoils,” said Tsubaki Kabelschlepp.

Separately, Tsubaki Kabelschlepp has reported that its new EasyTrax, QuickTrax and UniFlex Advanced series carriers are all designed to be opened quickly, making installation and replacement of cables and hoses easier and quicker.
