A versatile and adaptable height and slew monitoring system

Series 2HS

Height and slew monitoring for excavators

The Series 2HS is an intelligent height and slew monitoring system, designed to maximise safety and productivity in confined areas.

The system is a practical and effective way of monitoring and controlling the working height and rotation of machinery to ensure safe operation on site. It enables machine the operator or site manager to set safe working limits for heavy machinery, ensuring site hazards or risks are avoided.

The Series 2HS is fully approved by Network Rail as a low performance movement limiting device (MLD), and the Series 2HS+ is certified as a high performance MLD.

How does it work?

The Series 2HS combines an easy-to-use interface with high accuracy sensors and GKD’s proven safety software.

The system notifies the machine operator when the machine is approaching and breaching a set limit. An external audio alarm is activated when reaching the limit. An optional intelligent motion-cut prevents limitation infringements and allows only safe movement.

Suitable for use on tracked or wheeled excavators, backhoe loaders and other articulated boom machines.

Suitable for high or low performance operations

If you are undertaking Adjacent Line Open (ALO) or Overhead Line Equipment (OLE) operations and need to control height and slew, then the Series 2HS is an ideal system for you.

The Series 2HS has achieved Network Rail approval as a low performance movement limiting device, which means it can be used over 3000mm from the rail running edge.

The Series 2HS+ is approved as a high performance movement limiting device, which means it can be used up to 300mm from the rail running edge.

The 2HS+ also has additional safety features, such as a remote hydraulic shut off and a steering lock.

Dig mode and virtual walls

The Series 2HS offers the additional advantage of monitoring and setting dig depth limits, allow operators to increase their digging accuracy. This supports a more efficient approach of dig once, move once.

The system also has the unique flexibility of parallel or multipoint virtual walls.

This is ideal for working in confined surroundings or close to open traffic lanes, and when combined with height limits for working under overhead obstructions. Our technology ensures rotation and height limits are anticipated and not exceeded.
