A gantry crane is an overhead crane supported by freestanding legs. The crane moves on wheels, a hoist, trolly, or a rail system. Gantry cranes are beneficial for numerous warehouses, workshops, freight yards, shipyards, and railroads as an effective lifting solution. The lifting capacity of a gantry crane differs from a few hundred pounds to a few hundred tons depending on its size and features. This article provides information on what is the purpose of a semi gantry crane.
A semi-gantry crane is designed with one leg and uses a wall-mounted beam to support the other side of the unit. The semi-gantry crane has a crane mechanism, bridge, hoist, and trolley. These cranes can be installed indoors or outdoors depending on your specific needs. In most cases, a semi-gantry crane will be installed below an overhead crane to increase the work efficiency of the organization. The semi-crane doesn’t interfere with the operation of the overhead crane.
The semi gantry crane has two typical applications such as:
. Indoors – The semi-crane will be used under an existing overhead crane to offer more hooks and improve the productivity of the warehouse or workshop.
. Outdoors – When a semi-gantry crane is used outdoors, it is typically used near a building. It uses the existing runway structure to improve the cost-efficiency of the plant.
Depending on the loading capacity, a semi gantry crane can be formed in a single girder or double girder crane. The double girder crane is a cost-effective alternative to the installation of a bridge crane in a workshop. It can be installed whenever the installation of a bridge crane is not practical due to requiring a raised run-way structure. The double girder semi gantry crane has a great load capacity & minimum deadweight. It has precise & stable geometry to guarantee the safety and security of your operation. The load hook could be raised between the two girders to provide maximum lifting heights. The double girder crane can be controlled by a traveling station or radio controls.
When you are in the market to purchase a new semi gantry crane, you need to consider the following factors:
- The load capacity of the gantry crane in tons
- The span of the semi-gantry crane in meters
- The maximum lifting height of the crane
- What kind of material would the semi-gantry crane lift?
- Traveling length of the crane, and whether you need the manufacturer to provide the rail for you?
- The electric power supply of the crane
- How many times do you plan to operate the crane per hour and how many hours per day?
The safety configuration of the semi gantry crane is an important feature to consider when shopping for a quality gantry crane in the market. The unit should have an overload protection feature. It should also have stroke and height protection and short circuit protection. These are the most important factors to consider when investing in a semi gantry crane in the market.
