This product adopts a three-stage telescopic arm for the lifting operation of the support frame.
Product Introduction:
This product adopts a three-stage telescopic arm for the lifting operation of the support frame. The base of the support frame is controlled by a transverse angle-adjusting hydraulic cylinder and front and rear rotating hydraulic cylinders, allowing for a leveling adjustment between 3m to 4m. It offers excellent top contact effect and is suitable for rectangular, arch, and trapezoidal tunnels.
Technical Features:
High support strength, with a rated working resistance of up to 30kN.
Good synchronization of the single main arm extension, high structural reliability, and low failure rate.
The support frame is controlled by an angle-adjusting hydraulic cylinder, allowing the left and right swinging angle to reach ±25°.
The front and rear flipping of the support frame is controlled by a longitudinal rotating hydraulic cylinder, making it safe and convenient for securing the anchor mesh.
The support frame can extend laterally and forward, providing a large top contact area.
Load-sensitive control is used, offering high control precision.
