Classification of gantry cranes by Outriggers\

Gantry cranes can be divided into several categories according to the characteristics of outriggers. If you don't understand it, please take a look at our introduction in this issue!

According to the configuration of outriggers, gantry cranes are divided into three types: single outrigger, double outrigger and high and low outrigger. The gantry crane with single leg is called semi gantry crane. The crane traveling mechanism on the side without leg runs along the special crane track or special viaduct track laid in the plant, warehouse, etc. Cranes with high and low outriggers are specially designed to meet the requirements of terrain. When the leg pressures of the outriggers on both sides of the gantry crane are quite different, and different layers of running trolleys are required, the scheme of high and low outriggers can also be adopted.

According to the nature of outriggers, gantry cranes can be divided into two types: space rigid outriggers and plane flexible outriggers. The intermediate rigid outrigger has good spatial rigidity, which can not only bear the horizontal load in the outrigger plane (horizontal load of the crane), but also bear the horizontal load in the gantry plane (longitudinal horizontal load of the crane); The rigidity of the flexible outrigger in the gantry plane (perpendicular to the outrigger plane) is very poor, so it can only bear the horizontal load in the outrigger plane. Large span gantry cranes often use a rigid outrigger and a flexible outrigger to prevent rail clamping due to temperature changes.

Gantry cranes are divided into L-shaped, C-shaped, O-shaped and U-shaped box shaped open outriggers according to outrigger types; Solid web closed outriggers and box closed outriggers with and without trolley passage. L-shaped and C-shaped outriggers are mainly used for single main beam gantry cranes, O-shaped and U-shaped outriggers are used for double beam gantry cranes, and U-shaped outriggers are widely used in rubber tyred container gantry cranes.

The above is the classification of gantry cranes according to outriggers introduced by Shandong gantry crane manufacturer this time. I hope it can help you.
