Semi Gantry Crane

Work environment temperature: -25℃～+40℃, relative humidity ≤85%; Crane control mode: Pendant control / Wireless remote control / Cabin control

Semi-type gantry cranes (BMH type, BMG type) are used with CD1, MD1, other types of electric hoist or LH hoist trolley or QD trolley. It is suitable for lifting, transporting, loading and unloading in open-air operation sites such as stations, wharves, warehouses, construction sites, cement product yards, machinery or structural assembly yards, power stations, etc. It is also suitable for working in indoor workshops.
The support legs of the semi-gantry crane have a height difference, which can be determined according to the civil construction requirements of the use site.
It is composed of lifting mechanism and trolley, single main beam (or double main beam) , support leg, and end carraige, electric control box, operating system, and safety protection system, etc.

Semi gantry crane is a special form of Gantry Crane. Just as shown in the picture, at one side of the crane, this gantry crane for sale runs on an elevated runway system like a overhead crane along the length of the factory.
At the other side, it just runs like a standard rail mounted gantry crane. This special overhead gantry crane for sale allow you extend your workplace by not needing a runway system from the top of the building.
Compared with gantry crane, it uses the structure of the plant instead of a new leg of the crane itself. Undoubtedly, it owns a more cost effective. Considered that semi gantry crane doesn't depend entirely on the plant, this special structure gantry crane has an advantage on the flexibility over EOT crane.

BMH type 2-20t electric hoist semi-gantry crane

There are two typical applications:
Indoors, it is often used under the existing overhead cranes to provide more hooks, thus improving the the productivity of your factory.
Outdoors, often is used near the building, making full use of the existing runway structure, thus improving the cost efficient of your factory or plant.

Depending on the loading capacity, this special kind gantry crane can be formed in single girder gantry cranes, as well as double girder gantry crane. So, if you want to see more technical parameters, you can just get a reference from corresponding Overhead Cranes or Gantry Cranes.

The structural characteristics of semi-gantry cranes include components such as the support, cantilever beam, trolley, trolley carriage, hoisting mechanism, and electrical control system.

Support: The support of a semi-gantry crane is usually established on the ground and supports the weight and load of the entire crane through the support. The support is usually composed of a steel structure, with sufficient strength and stability to ensure the safe operation of the crane.

Cantilever beam: The cantilever beam of a semi-gantry crane is one of its most important components. It extends to the working area and supports the hoisting mechanism and load. The structure of the cantilever beam is usually divided into truss structure and beam-slab structure, which can be selected according to the needs of the lifting task.

Trolley: The trolley is a component of the semi-gantry crane. It moves along the cantilever beam and is responsible for moving the load from one position to another. The trolley is usually composed of components such as motors, reducers, wheels, and brakes. Trolley carriage: The trolley carriage is another component of the semi-gantry crane. It is responsible for moving the hoisting mechanism on the trolley to the correct position for hoisting and lowering the load. The trolley carriage is usually composed of components such as motors, reducers, wheels, and brakes.

Hoisting mechanism: The hoisting mechanism is one of the core components of the semi-gantry crane and is responsible for hoisting and lowering the load. The hoisting mechanism is usually composed of components such as winches, steel wire ropes, hooks, and weight meters.

Electrical control system: The electrical control system is another important component of the semi-gantry crane and is responsible for controlling the operation of the crane. The electrical control system usually includes components such as control boxes, cables, motors, and sensors.
