Product Presentation of Excavator Boom

        The long arm of the excavator is made of Q355B steel, which has good strength and rigidity. The shaft sleeve of the extension arm is generally made of 45# steel and lined with a 40Cr bushing. The lubrication of the butter reduces the shear force generated by the frequent rotation of the shaft and the shaft sleeve, thereby prolonging the service life of the extension arm. The bushing is enlarged. It is located between the main body bracket and the working arm and is equipped with an extension arm. The extension arm is connected and supported by an oil cylinder. Extending the arm working cylinder and bucket cylinder, inside and outside the cockpit, the corresponding control system is equipped with a set of cylinders, which work in conjunction with the control arm. The telescopic work of the cylinder and the bucket cylinder can more than double the stroke of the bucket, and the stroke can be Higher, deeper, and farther. Especially suitable for mines, docks, warehouses, flood relief and special occasions. This is a major breakthrough in the transformation of mining machinery and has great practical value.

FAQ of excavator long arm

Q1: Why not have boom and stick cylinders in the plan?
A1: First, the whole long arm is lengthening, but the boom just lengthening from its middle sleeve to its end, so the original boom and stick cylinder can be used. Second, using the original parts can save you cost.

A2. Generally speaking, the 30-40 excavator longest arm suggests to be 8 meters, and can configure 0.1 cbm bucket, with no need for an extra counterweight. 55 excavator's longest arm suggests to be 12 meters, which can configure 0.1-0.15 cbm bucket, which needs 0.5 ton extra counterweight. 60-80 excavator longest arm suggests to be 12 meters, can configure 0.15-0.25 cbm bucket, need 0.5-0.7 ton extra counterweight.
It is not recommended to extend boom arm to longes the t length as mini excavator is easy to slosh.
