Series 1H

Height limiter for excavators and heavy machinery

The Series 1H is a reliable and cost effective height limiting system suitable for self-installation.

The system is designed to protect workers from overhead danger when it is difficult to judge the actual height of the machine from within the cab.

How does it work?

The Series 1H is an entry level height limiting system that monitors the angle of a single boom and provides a motion cut signal output when the angle is exceeded.

The machine operator is able to define a preset limit of the machines boom on the operator station, preventing movement of the boom outside of the pre-set limit.

The Series 1H consists of a gravity referenced angle sensor mounted on the lifting boom and a display at the operator station. This ensures that height limits are maintained accurately even when the machine is tilted when working on an incline.

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

Key features

The Series 1H has numerous features that make it an ideal, cost effective height limiting system. These include:

  • Simple operator controls
  • LED display with integrated key switch
  • Suitable for self-installation
  • Gravity referenced angle sensor (rather than a sensor referenced against the machine body)
  • Accurate, proven and reliable
  • Hydraulic motion cut once height limits are breached
