1SL Slew Limiting System

Enquire Now

GDK Technic manufacture safety technology for construction machinery and people working around plant.  GDK height and slew limiting systems are simple to use, excellent value for money and allow for full hydraulic cutout as an option. GDK height and slew limiting systems should be used if you are working under powerlines with an excavator, working in confined spacing and need to limit slew on your machine or want to reliably notify machine operators when your personal are working close to machinery (without relying on the operator watching a video screen).  Talk to your Global Survey Machine Control specialist today about how solutions from GDK can help solve your safety problems.

The SlewGuard motion control system is a simple, cost effective slew limiting solution designed to guarantee safety and prevent machine damage when operating in confined spaces.

APPLICATION: The SlewGuard system is intended for use on excavators and cranes in the construction and utility maintenance industries where machines are restricted to working in confined spaces and there is a requirement to limit the slew movement of the machine.

HOW IT WORKS: SlewGuard allows the machine operator to quickly and easily set left and right slew limits from the operator station, and then restricts the machine to working within the permitted 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.

    The system can be installed by any competent engineer, and there is no calibration required.
