Product Description:

L leg heavy duty  gantry crane with electric crab


L type trolley gantry crane with hook is matched with trolley, a kind of track travelling mid-light type crane. It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, and where additional supporting steelwork would result in a loss of floor area. It can be constructed with a cantilever to allow handling outside the rail centers.
Product component
This gantry crane is composed of girde, L type support leg, crane travelling organ, trolley, electric equipment Etc.
The frame adopts box-type welding mechanism, the L type single leg is welded structure in order to increases the work space, and it is convenient for the transportation, installment and maintains. Crane travelling mechanism adopts separate drive.

Application
such as: cement plant, granite industry, engineering industry, port, railway, civil aviation, food, papermaking, construction, electronics industries, and warehouses, etc.

Control methods
1. Pendent line with press button
2. Cabin control
3. Remote control

Q:What is the operating procedure for double girder overhead cranes?
Each time the first lifting of heavy objects (or load to the maximum weight), should be hanging from the ground height of 0.5 meters, the weight down again, check the brake performance, confirm the reliable, and then normal operation.
Q:Is the gantry crane and the gantry crane the same concept?
Its metal structure like a door frame, carrying the main beam under the installation of two legs, you can walk directly on the ground track, the main beam at both ends can have extended cantilever beam.
Q:What procedures do you need to install second-hand gantry crane?
2, the installation of the installation staff to provide special types of workers, technical supervision bureau will come to check.
Q:What are the safety sources of gantry cranes?
Heavy tonnage objects when lifting, should first slightly off the test hanging, to confirm hanging stable, good braking, and then increased, slow operation.
Q:What is the website of the gantry?
Need to know the name, for location, document number can query.2, enter the document number, name and type of document.
Q:What are the uses and advantages of gantry cranes?

Q:What is the gantry crane of a hydropower station?
Mainly used for lifting and opening and closing the gate, can also be installed operations.
