Traveling gear

Each walking device is equipped with a high torque axial plunger motor, which is then reduced by a planetary gear system to increase traction. The excavator can be moved forward or backward smoothly by two pedals or walking control rods.

Hydraulic System

The core of the system is EPOS^TM(Electronic Power Optimization System). It can optimize system efficiency under any working conditions and minimize fuel consumption. New EPOS^TM engine control unit is connected to the engine via a data transmission line, coordinating the operation of the engine and hydraulic system. The hydraulic system supports both independent and combined operation modes.

· Two walking speeds can ensure both walking torque and walking speed

· The interactive sensor control main pump control system can save fuel

· Automatic speed reduction system

· Two operating modes, two power modes

· The flow of the optional equipment pipeline can be controlled by one button

· Computer aided pump power control

Chassis

A robust chassis, all welded structures are designed to limit stress concentration. High-strength materials are selected to ensure durability. The side chassis is directly welded to the X-frame. Heavy wheels, idler wheels, and sprockets all use floating oil seals. The three-toothed track plates are treated with induction quenching to improve wear resistance, and the connecting pins are also quenched. Hydraulic travel dampers can filter out most of the vibrations during movement.
