Container spreaders are equipments to handle containers, QSHI is professional in manufacturing all kinds of container spreaders, to meet differenct clients needs;

Below we introduce several of QSHI container spreaders mostly applied in all yard, container ports;

Semi-automatic spreader

The semi-automatic spreader is directly suspended on the hook of a general gantry crane for container loading and unloading operations. It has no power source. The lifting and lowering between the spreader and the container requires the lifting and lowering of the hook, and the rotation of the rotary lock is driven by the ratchet mechanism. .

 

The spreader is convenient to change and install, has a simple structure, is light in weight and low in cost, and is suitable for a comprehensive freight yard where containers and cargoes work together.

 

It is a transitional device for railway container loading and unloading;

Rotary spreader

The slewing spreader is mainly used for loading and unloading containers with general gantry cranes. It is also directly hung on the hooks of general gantry cranes. It is an economical and fast effective method for existing general gantry cranes to improve container operation performance.

 

It is equipped with a hydraulic power device, and its biggest feature is that it has a 360° full rotation function in the plane. The driver can control the rotation of the spreader at will with a foot switch, which greatly facilitates the alignment and stacking of container loading and unloading. The twist lock of the spreader is driven by the oil cylinder, and the lifting hook is no longer required to complete, which is convenient to use and high in efficiency. At the same time, the spreader is equipped with mechanical and electro-hydraulic double protection to prevent malfunction.

Telescopic spreader

Telescopic spreader is the most commonly used type of spreader for container cranes. It adapts to the lifting operations of containers of different specifications by automatically changing the length of the spreader. The telescopic spreader is usually composed of a hanger structure, a twist lock device, a guide device, a telescopic device, a hydraulic system and a variety of interlocking safety devices.

 

The structural frame of the telescopic spreader has single-beam frame and double-beam frame. The single-beam frame spreader has a slightly larger height than the double-beam frame spreader, but its own weight is relatively lighter.

 

The telescopic action of the telescopic device can be completed by a hydraulic cylinder, a chain drive, or a combination of the two. In the rotary lock device, the hydraulic cylinder pushes the connecting rod to drive the crank to rotate the rotary pin by 90°, so as to realize the opening and closing of the rotary twistlock at top corner of the containers;
