Semi gantry crane is a variation of gantry lifting equipment, which is widely adopted when the space is limited. This single leg gantry crane differs from full gantry crane in that it utilizes a wall-mounted I beam on one side and A-frame leg on the other side to accomplish the movement. This gantry crane is primarily used in manufacturing and material handling industries to handle heavy loads. The gantry cranes have two main configurations including single girder and double girder to suit different applications.
Different Types of Semi Gantry Crane
We mainly produce two models of gantry cranes for your choice. And different styles and designs are available to meet various operation and application requirements.
AQ-BMH semi gantry crane is a kind of single girder crane, usually equipped with AQ-CD1 or AQ-MD1 electric hoist. Besides, the European standard electric hoist is also in option. This type of gantry crane is designed for general use and the maximum lifting capacity can reach 16 ton. The steel structure of the gantry crane usually adopts box form, and truss gantry crane is more often used in outdoor workplaces where have strong winds.
Single girder semi gantry crane parameters:
- Load capacity: 3-20t
- Span: 8-30m
- Lifting height: 6-18m
- Lifting speed: 0.33-8m/min
- Trolley running speed: 20m/min
- Crane running speed: 20m/min
- Work duty: A3-A4
AQ-BMG semi gantry crane is generally the same with AQ-BMH type except it adopts double girder design, so it can reach a larger capacity and greater lifting speed compared with the single girder type. This type of crane also has higher working level.
Double girder semi gantry crane parameters:
- Load capacity: 5-32t
- Span: 12-30m
- Lifting height: 6-12m
- Lifting speed: 6-11.5m/min
- Trolley running speed: 37-40.1m/min
- Crane running speed: 37.7-40.1m/min
- Work duty: A3-A6
When selecting a semi gantry crane, you need to think about a few things including your required capacity, span, lifting speed, application, working environment and other designs to make the right choice.
Knowing the Installation of Semi Gantry Crane
The semi gantry crane has simple assembly and disassembly with one side mounted on an elevated runway and the other side mounted on the ground track. This gantry lifting equipment can also be relocated in other working areas easily. When installing gantry crane, you should first read the installation manual and strictly follow the instructions.
