12-20 Ton Excavator Hydraulic Telescopic Sliding Arm 7.5 10m Extendable Arm for sale Q355B

12-20 Ton Excavator Hydraulic Telescopic Sliding Arm 7.5 10m Extendable Arm made of Q355B for sale 

The excavator sliding arm is mainly composed of an upper sliding arm and a lower fixed arm. The upper sliding arm is installed above the lower fixed arm, and the two are connected to each other through the upper and lower track rails of the sliding arm. The upper sliding arm can be freely extended and retracted through an oil cylinder on the upper part of the lower fixed arm, thereby adjusting the excavation depth and turning radius

working principle
By the telescopic movement of the oil cylinder, the upper sliding arm is driven to slide on the track of the lower fixed arm, achieving the telescopic change of the small arm length. This design allows excavators to flexibly change their working radius and depth in narrow spaces or when adjusting the excavation range, adapting to different construction needs
