Portal cranes are divided into two types of single-boom and four-link according to the structure of the boom.

The single-boom portal crane has the features of simple structure, light weight and large amplitude. The four-link portal crane adopts an excellent combined boom system to realize the horizontal movement of goods during the luffing process, with the features of horizontal small fall of spreader luffing, stable operation and high work level. Both types of portal cranes can meet the loading and unloading requirements of general cargo, bulk materials and containers. They have the characteristics of wide application range, high operating efficiency, convenient use and maintenance, safety and stability.

The electric drive adopts the unique technology of full digital AC frequency conversion and PLC speed regulation control, with flexible control and high precision. The quality of the whole crane is guaranteed by purchased parts from well-known domestic and foreign brands.

At present, the specifications of main products are MQ1025, MQ1030, MQ1625, MQ1630, MQ1635, MQ2525, MQ2530, MQ2535, MQ4025, MQ4030, MQ4035 single boom portal cranes and four-link portal cranes.

Provide various structural forms of grab rope stabilization devices, with good rope stabilizing effect, which can significantly restrain the swing of the spreader.

Two-cranes cooperative operation technology has high control precision and good cooperative effect.

The hinge point of the boom moves up to realize the Z-winding of the wire rope, which prolongs the service life of the wire rope and is convenient for maintenance.

The automatic slewing following technology for container spreader improves operation efficiency and safety.

Vector frequency conversion and electric energy feedback technology save energy and environmental protection.

Automatic fault detection and real-time data display technology are safe and reliable.

Provide multiple operation modes---manual ,semi-automatic remote operation with advanced technology and stable performance.

Its core technologies: operation, slewing positioning, intelligent following of spreader trajectory and intelligent safety protection.

A variety of safety measures, including strong wind alarm, safety dynamic scanning.
