Computerized Monitoring System Functions
The Computerized Monitoring System offers three main functions: quick and simple calibration of the hydrostatic drive system, alerting the operator of situations to prevent damage, and monitoring of hydraulic and electrical systems to aid service personnel.
Computerized Monitoring System Warnings
The Computerized Monitoring System offers three levels of warning.
The 953C also features a key start/stop switch and a speed mode switch.
Box-section main frame is designed to handle heavy loads, while Z-Bar linkage maximizes breakout force.
Main Frame Design
Strong box-section main frame design, with continuous, deep-penetration welds resists twisting loads to protect components from excessive wear.
Breakout force is exceptionally high due to the mechanical advantage of Z-Bar linkage design.
Keeps more track on the ground for maximum traction and stability. Several shoe options provide best match to job conditions.
Oscillating undercarriage allows movement of each track independent of main frame.
Swing Link Idler
Swing link idler permits horizontal idler movement, absorbing shock loads and maintaining proper track tension, while eliminating the need for shims and wear strips.
Tracks are sealed and lubricated to keep abrasives out and virtually eliminate pin and internal bushing wear to keep maintenance costs down.
Bolt-on Sprocket Rim Segments
Bolt-on sprocket rim segments allow replacement of worn sprocket teeth without opening the track chain.
Two-piece split master link allows easy track chain removal and installation.
Caterpillar Brand Undercarriage
Caterpillar brand undercarriage components are well-matched to each other and the machine for superior life and cost-effective operation.
