Double girder semi gantry cranes feature a double-beam structure, with a QD trolley or double hoist trolley for the lifting mechanism. They are commonly used for loading and unloading in open areas and warehouses, and are designed to maximize the use of space resources. which is mainly used in steel stockyards, mines, the concrete industry, warehouses, factories, port and ship building, etc.
Its proper lifting weight is 5 to 50 tons, proper span is 5 to 35 meters, Work duty: A5
Semi-gantry cranes are a versatile and cost-effective solution for lifting and moving heavy loads in industrial settings. They combine the design of an overhead bridge crane with that of a motorized gantry crane, The crane is typically powered by a powerbar and collector assemblies along the elevated runway side of the Semi Gantry Crane and distributed by a festoon system to the hoist trolley.
Semi-gantry cranes can be controlled either by a wired pendant control or with an optional crane radio remote control system.
There are two types of semi-gantry crane, one is a single beam semi-gantry crane, one is a double girder semi-gantry crane, A single beam semi-gantry crane is a type of gantry crane that has one beam supported by two legs, while a double beam semi-gantry crane has two beams supported by two legs. Both types of semi-gantry crane are used to lift and move heavy loads in industrial and commercial settings.
1.Overload protection.
2.Main lifting motor with thermal protection.
3.Hooks with latch.
4.Rubber buffers.
5.Protective earthing.
6.Crane switch and travel and end switch
7.Emergency switch can stop all movement when any dangerous happened.
8.Sub-assemblies characteristics are tested before assembly.
9.All cranes must be pre-assembled and tested before leaving factory and offer the certification of test.
