CAT 345C L manual SmartBoomTM, Structures, Variable Gauge Undercarriage

SmartBoomTM

Reduces stress and vibrations transmitted to the machine.

Rock Scraping. Scraping rock and finishing work is easy and fast. SmartBoom simplifies the task and allows the operator to fully concentrate on stick and bucket, while boom freely goes up and down without using pump flow.

Hammer Work. It has never been this productive and operator-friendly. The front parts automatically follow the hammer while penetrating the rock. Blank shots or excessive force on the hammer are avoided resulting in longer life for the hammer and the machine. Similar advantages are applicable when using vibratory plates.

Truck Loading. Loading trucks from a bench is more productive and more fuel efficient as the return cycle is reduced while the boom down function does not require pump flow.

Material Handling. It is more efficient and productive due to faster return cycles. Unloading barges is easier because SmartBoom avoids excessive force being put on the floor of the barge allowing the operator to fully concentrate on production.

Structures

Structural components are the backbone of the machine’s durability.

Carbody Design. The advanced carbody design stands up to the toughest applications.

Modified H-shaped, box-section carbody provides excellent resistance to torsional bending.

Variable gauge undercarriage has track roller frames which are bolted to the carbody and can be retracted for shipping.

Robot-welded track roller frames with fabricated U-section design.

Robot welding ensures consistent, high-quality welds throughout the manufacturing process.

Upper Frame. The rugged main frame has been narrowed to improve transportability and is designed for maximum durability. Robot welding is used for consistent, high-quality welds. The main channels are box sections connected by a large diameter tube in the boom foot area to improve rigidity and strength. The outer frame utilizes curved side rails for rigidity against bending and torsional loads.

Track Roller Frames. The track roller frame is made of thick steel plate that is bent into a U-shape and welded to the bottom plate to create a box structure. The box structure design provides increased rigidity and impact resistance.

Variable Gauge Undercarriage.

The long variable gauge undercarriage is standard, providing a wide, stable base for operating, or a narrow gauge for reduced shipping width. The track roller frames are bolted to the carbody, and can be placed in two positions.
