Types of Quay Cranes

Quay Cranes are widely used in modern ports, and the right choice of Quay Cranes can help to increase the efficiency of cargo handling. However, in some special environments, such as areas with dense construction around the quay or near airports, there are strict restrictions on the height of quay cranes. This article will introduce the types of quay cranes categorized by height restriction, to provide professional selection guidance for ports facing the challenge of space constraints. Please continue reading on:

For the special environment of the height limit needs, the front main beam can be used in a variety of design forms to adapt to different height restrictions, including pitching, sliding, bending and main beam lifting and other structural design.

1. Pitched main girder

In working wind conditions, the main girder is tilted up by 45°, and the headroom under its main girder can safely avoid the ship's superstructure. The top height of the main beam will not affect the route. Once in a non-working wind, the main beam needs to be tilted to 80 ° and hooked.

2. Telescopic main girder

The front main girder of this type can be telescoped by a set of driving mechanism. During operation, the front main girder extends seaward, and during non-operating time, the front main girder can be slid and contracted into the land-side frame. This type of quay crane is mainly suitable for places where the clearance height requirement is more stringent. This type of front main girder is a cantilever girder, subject to a large bending moment, so the main girder section size is large, the weight is large, and usually uses a truss structure to reduce the weight of the main girder.

3. Bending main girder (gooseneck type)

This type of main girder is to make the front main girder into a bendable form, when loading and unloading operations, the main girder can be placed in the horizontal position, and tilted up in the form of a bend, which ensures that the highest point of the quay crane does not exceed the allowable height of the headroom, which is commonly known as gooseneck main girder because of the shape of its gooseneck.

Each type of quay crane design has its own unique advantages, and the selection of the most suitable form depends on specific application scenarios, operational requirements, and space constraints.
