Description
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.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Wide working range
The rotary platform of portal slewing crane can rotate 360°, the boom can be tilted, and the working area is large and can be covered in all directions. In the harbor, shipyard and other complex environments, it can lift goods from different positions, reducing the time of equipment movement.
High operating efficiency
Lifting, luffing, slewing, walking (partially) and other mechanisms work together, and the operating speed can be adjusted, so it can load and unload goods quickly and accurately, and improve the speed of logistics turnover in ports and the efficiency of shipyard construction.
Highly adaptable
Adapt to a variety of harsh environments, such as harbor salt spray, shipyard complex space. Parameters and configurations can be adjusted as needed to meet the needs of different scenarios.
Accurate lifting
With advanced control system, it can precisely control the lifting operation with small error, which can protect valuable or precise goods and guarantee the safety and quality of operation.
