The system makes use of the six available inputs for a chassis enable, and slide in and out digital inputs . The result is smooth ramp up and ramp down of each crane function independent of any other functions for increased operation efficiency and safety. To ensure repeatable and constant performance at all temperatures and loads. The MHR manages the output to the hydraulic valve bank as the transmitter is actuated. The display shows the overall health of the machine, and in the event of a malfunction, error messages are displayed to quickly pinpoint the issue. The readouts are not alpha-numeric codes, but rather clearly spelled out descriptions for ease of troubleshooting. The MHR offers an LCD graphic display that allows for viewing of system settings and a series of readouts that monitor the overall operation of the system.

The radio system has custom control logic for ease of operation, and added safety from the radio system and the machine mounted controls. As well as providing outputs, this control system also has inputs from toggle switches located on the machine- mounted control box. The Enrange MHR system controls the tracks in a forward and reverse motion, and the cat tracks can be slid in or out to adjust the width for greater stability of the machine. The mini-derrick chassis is controlled by a fully proportional hydraulic system for machine travel and site setup operations. The wireless controller features components of a radio receiver and a hydraulic controller in a single package, reducing installation time and overall costs while increasing operation efficiency and safety. worked with Pitman to improve the performance, productivity and safety of its Tiiger mini-derrick chassis by implementing its Enrange MHR wireless controller system scaled to meet the specific needs of the application. The machine has sliding tracks that adjust the width, allowing it to fit through narrow spaces. The Pitman Tiiger derrick chassis is a mini cat-track carrier that is ideal for applications in backyards, narrow right-of-ways, and remote hard-to-get-to locations. Pitman Utility Products of Grandview, MO, has been designing and manufacturing utility and construction equipment since its founding in 1950.
