Types of Port Cranes

One of the basic infrastructures for handling merchandise and ships are all types of port cranes, especially in commercial ports where loading, unloading, storage, and unloading are key actions for the development and operation of these ports.

The cranes are used for loading between the port and the ship, in order to organize and stack it, but also for the stranding of ships, dry storage, ship repair, or auxiliary operations.

The latter, depending on the activities that must be developed and available spaces can be installed in different structures (for example, on the top of a telescopic gangway of a column and/or tower type), and be equipped with different accessories or ranges of scope; they can also have a wide variety of accessories, such as winches, hydraulic handling mechanism, remote controls, load limiter, and counterbalance valve, among others.

Container crane

In a modern port environment, reliability and productivity are the key parameters.

The Liebherr container-loading cranes (STS) reach an availability rate of up to 99.6% during actual operation on the ship.

Gantry cranes for container loading are designed specifically for each client according to their specific requirements, with different costs and characteristic data in each case and with sizes ranging from the Panamax class to the largest Megamax cranes.

Safe workloads of 40 to 120 tons are possible through individual, double or tandem loading.

How tall are container cranes?

How tall are container cranes?

Megaships can be up to 1,300 feet long and carry nearly 23,000 cargo containers. Containers are stacked up to 12-high above deck on the largest vessels. Taller cranes are required to reach the top of the stacks.

What is the meaning of gantry crane?

A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. The terms gantry crane and overhead crane (or bridge crane) are often used interchangeably, as both types of crane straddle their workload.

What is the difference between a bridge crane and gantry crane?

A gantry crane is slightly different from a bridge crane. The general premise is the same, but the operation is different. Some gantry cranes ride along a track installed on the floor, or use a V-groove caster to keep movement in a straight line. Gantry cranes are usually less expensive than an overhead bridge crane.

Do I need a Licence for a gantry crane?

A licence is not required for bridge or gantry crane operation, providing that: It is remotely controlled by way of pendant or radio, and the crane does not have any more than three powered operations.
