Product Presentation of Excavator Extension Arm

     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, lined with a 40Cr bushing, and the lubrication effect of butter reduces the shear force generated by the frequent rotation of the shaft and the shaft sleeve, thereby prolonging the service life of the extended arm. The shaft sleeve is enlarged. Using a selection of the toughest wear-resistant steels, we can produce excavator long arms for Cat, Demag, Doosan, Hitachi, Hyundai, JCB, Kobelco, Komatsu, Liebherr, Volvo and other popular brands.

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 extends 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 most extended 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 most extended arm suggests to be 12 meters, can configure 0.15-0.25 cbm bucket, need 0.5-0.7 ton extra counterweight.
