Load limitation system for

hydraulic lifts

More information

CHD Load limiter pressure sensor

CHDs are a complete limitation system, composed of a pressure cell and limiting equipment. Cabin load variations by the entry or exit of loads or passengers become pressure variations which in turn convert hydraulic line pressure into electrical signals measured by its integrated control system.

Occupying a minimum space, the CHD system is installed in such a way that it does not interrupt or alter the fl ow of hydraulic fl uid. Installation can be done easily using a T-connection in any position on the pressure line.

The CHD sensor is robust in design, supporting up to 100 bar, and compact without infl uencing the reliability of the pressure system, while providing the ease of integrating a load limiter into the lift or forklift. The sensor has the standard thread in hydraulic pressure connections and adapters are off ered in other sizes so you will always have the proper solution for your installation.

Get the best of performance by using app Tools ng2 Pressure pipeline Within the CHD family some models integrate Dinacell's M NG technology. This technology allows the fi rmware update and the possibility to connect the (1) GD-WiFi device to the computer. This accessory allows you to confi gure, calibrate, and obtain installation status information on any device that supports the Tools ng2 app.
