Caterpillar Booms

The parts with codes Caterpillar 6T1382, 156-4208 and 156-4209 are high-strength pivot, connecting, and carrier boom parts used in the boom and arm connection areas of Caterpillar construction machinery. They are specially developed components to strengthen the joint points operating under heavy loads of the machine and provide stable movement capability.

These parts play a critical role in balancing the load transfer in the boom system that must function at full performance and assisting the smooth operation of the moving parts. To provide maximum durability in these areas subjected to continuous impact, pressure, and vibration during operation, they are made of high-strength alloy steel.

While the Caterpillar 6T1382 model serves as a supporting element in the general connection and power distribution of the boom, the 156-4208 and 156-4209 models are parts that are mainly used as pivot and arm connections, carrying the central points of the movement. Thus, the boom’s opening, closing, and load lifting movements are carried out stably, safely, and with maximum efficiency.

Since these parts are manufactured in exact compliance with the original Caterpillar dimensions, they do not require any extra processing during assembly. By working in harmony with pins and bushings on their precisely machined surfaces, they reduce wear, maintain connection tolerances, and reduce maintenance costs.

In Caterpillar machines used in heavy field conditions such as construction, excavation, earthmoving, mining, and road construction; these parts are fundamental components that increase the boom’s life, enhance performance, and ensure safety. With its high strength, long service life, and trouble-free operation, it is an ideal spare part solution for professional users.
