Series 1S

Slew control for excavators and heavy machinery

The Series 1S is a simple, accurate, cost effective slew limiting system suitable for self-installation.

The system is designed to guarantee safety and prevent machine damage when operating in confined spaces.

How does it work?

The 1S allows the machine operator to quickly and easily set left and right slew limits from the operator station. These then restrict the machine to working solely within that pre-defined slew sector.

As the left or right slew limit is reached, a hydraulic solenoid valve is released to cut off the relevant slew hydraulic service, and therefore prevent the machine from entering the exclusion zone. Slew operation in the opposite direction – back into the “safe” zone – is still permitted.

Suitable for use on: Tracked excavators, wheeled excavators, backhoe loaders, tractors and lorry loading cranes.

Key features
