Location — Grandview, MO
Application — Mini Digger Derrick and Aerial Bucket
Products Used

The Pitman Tiiger is a combination digger and aerial device with a tracked carrier that is perfect for applications in backyards, narrow right-of-ways, and for remote locations. This machine has been designed to fit through 32-inch gates and move to work sites and backyards without damage to the area. This unit has a 40-foot work height and a 40-foot sheave height in a single compact unit.

The mini digger derrick is controlled by a fully proportional hydraulic system for travel and functional operations. Position, rotation, and load sensors are used to provide the necessary feedback to the master controller and operator for safe machine use.

Magnetek's compact Enrange MLTX bellybox transmitter is included in the system and offers precise proportional control with sealed levers or joysticks. Military-grade auxiliary function switches are used to increase application flexibility. It incorporates the latest polymer technology in a lightweight, comfortably contoured, yet durable case.

Magnetek also provided the Enrange CAN-6, CAN-Bus wireless radio receiver, with both digital and analog outputs. The compact CAN-Bus receiver communicates via J1939 commands to the hydraulic valve controllers, and it can provide digital or analog outputs as well, which can be controlled by the CAN-bus system. The control package with the CAN modules were packaged into a convenient single control box that significantly reduces costs, frees up valuable space on the diggers, and keeps everything in one spot for easy maintenance or trouble shooting.

The CAN-Bus controls manage the output to the hydraulic valve bank as the transmitter is actuated. This ensures repeatable and constant performance at all temperatures and loads. The result is smooth ramp up and ramp down of each crane function independent of any other functions for increased operation efficiency and safety.
