Portal Slewing Crane, also called a portal boom crane, is used for loading and unloading operations with a grab or hook at the front of port terminals and open-air stockpiles. It has a strong lifting capacity of tens to thousands of tons and can easily lift various heavy objects. The Portal Slewing Crane is divided into two types: single-arm and four-link according to the boom structure. Its 360° rotating platform and tilting jib system provide a wide range of working ranges, coordinated and adjustable speed of the working mechanism, and efficient operation. The advanced control system can adapt to various harsh environments and different operating scenarios. With a sturdy and durable structure and flexible travel mechanism, it is an ideal solution for operations in ports, shipyards, etc.
El accionamiento eléctrico adopta la tecnología única de conversión de frecuencia Ac totalmente digital y control de regulación de velocidad PLC con control flexible y alta precisión.
At present, the specifications of the main products are MQ1025, MQ1030, MQ1625, MQ1630, MQ1635, MQ2525, MQ2530, MQ2535, MQ4025, MQ4030, MQ4035 single boom portal crane and four-link portal crane.
The structure of the portal slewing crane can be mainly divided into two major parts, including the upper slewing part and the lower non-slewing part. The upper slewing part includes boom system, herringbone frame, slewing platform, hoisting mechanism, slewing mechanism, luffing mechanism, machine room, and driver's room, etc., while the lower non-slewing part mainly consists of gantry, equalizing beam, running cart, rail clamping device, and windproof anti-tipping device, etc.
