WELLD Flat Top Tower Crane

Hoisting mechanism

The hoisting mechanism of WELLD tower cranes is crucial for vertical movement of loads. Its primary purpose is to lift and lower materials on a construction site. It comprises a motor, gearbox, drum, and wire rope, working in unison to provide the necessary power and control for precise and safe handling of heavy objects, enabling efficient construction processes.

Trolleying Mechanism

The trolleying mechanism of a tower crane is responsible for moving the hoist trolley horizontally along the jib. Its primary purpose is to position the lifting hook directly over the load to be lifted or the point where the load needs to be placed.This horizontal movement allows the crane operator to precisely control the placement of materials on a construction site, ensuring efficiency and safety during operations.

Slewing Mechanism

The slewing table, or slew ring, is crucial for a tower crane's operation. The primary purpose is to allow the crane's upper structure—jib, counter jib, and machinery—to rotate horizontally 360 degrees. This enables the crane to lift and place materials across a wide working radius without repositioning the entire crane.

Hydraulic Jacking Mechanism

The jacking mechanism in tower cranes facilitates self-erection. Its purpose is to progressively raise the crane's height by adding mast sections. This crucial system allows the crane to "grow" with the building it's constructing, providing the necessary lifting height for tall structures.
