Portal Bracket
Heavy-duty steel structure frame to support the whole machine and provide working space, usually with box beam design, featuring high strength and good torsion resistance.

Power Transmission System
Mostly adopts diesel-electric hybrid or all-electric drive, equipped with frequency conversion control to realize efficient energy conversion and smooth speed regulation.

Lifting mechanism
It is composed of motor, reducer, reel, and wire rope, adopting a double or multiple reels design, supporting fast lifting and lowering of containers, equipped with load sensor and height limiter, providing accurate positioning and overload protection.

Traveling Mechanism
Tire-type design, equipped with a hydraulic or electric drive system, with a variety of steering modes, to adapt to the demand of flexible transfer in the yard, some models are equipped with an automatic deflection correction system.

Trolley running mechanism
It controls the longitudinal movement of the whole machine along the yard, adopts the structure of multi-wheeled balancing beam to disperse the wheel pressure and reduce the damage to the yard floor, and is equipped with anti-collision and anchoring devices.

Trolley running mechanism
Drive the spreader to move transversely along the main beam, adopting rack and pinion or steel wire rope traction mode, with a precise positioning system (such as laser distance measurement), the error of the spreader to the box is ≤±10mm.

Specialized container spreader
Equipped with a rotary locking device as standard, it can automatically or manually lock the corner pieces of containers, and supports the switching of various box types from 20ft to 45ft, and part of the spreader integrates the functions of weighing and tilt angle detection.
