Product Specifications

Main and auxiliary lifting mechanism

. Pump and motor: dual variable speed regulation, high efficiency and energy saving. The winch balance valve and anti-slip hook technology are combined to ensure stable lifting and lowering of heavy objects;

. Winches brake: normally closed, built-in, wet, spring-loaded disc brake, spring force braking, oil pressure release;

. The variable hydraulic motor drives the planetary gear reducer to control the lifting and lowering of the main and auxiliary lifting. At the same time, it has good micro-action performance, and the fast gear can achieve rapid power increase of the main and auxiliary lifting;

. The variable hydraulic motor can automatically adjust the displacement according to the load to achieve the maximum winch speed;

. High-quality anti-rotation wire rope is selected, with high hoisting safety and long service life;

. The folding line machine-added drum has high precision and good reliability, and the multi-layer winding does not mess up the rope;

. The bag-type rope head is selected to make the wire rope easy to disassemble and assemble.

Luffing mechanism

. Including: main boom luffing mechanism, auxiliary jib luffing mechanism;

. Each luffing device adopts a folding drum, driven by a hydraulic motor through a planetary reducer, can realize a variety of compound actions and has good micro-speed performance.

Slewing mechanism

. Slewing brake: Normally closed, built-in, wet, spring-loaded disc brake, spring force brake, oil pressure release;

. The slewing system has an integrated slewing buffer valve with free sliding function, smooth slewing start and control, and excellent micro-motion;

. Unique slewing buffer design, more stable braking;

. Slewing drive: External meshing slewing drive, can slew 360°, maximum slewing speed 1r/min. Maximum driving pressure can reach 20MPa;

. Slewing lock: Cylinder locking device, ensures that the vehicle can be locked in four directions after work or transportation, convenient and reliable;

. Slewing bearing: Three-row roller external gear slewing bearing is adopted.

Counterweight

. The combined counterweight is easy to assemble and disassemble, and can be self-loaded and unloaded, making transportation more convenient;

. The stacking method of pallets and counterweights is adopted, which is easy to assemble, disassemble and transport.

Upper structure

High-strength steel welded frame structure, no deformation or torsion, reasonable layout of parts, easy maintenance and service.
