Singel Girder Gantry Crane with Trolley and L Type Legs
L type single beam gantry crane 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.
This crane is mainly used in steel stock yard, mine, the concrete industry, warehouse, factory, harbor and ship building, etc. The working ambient temperature is generally -20°C-40°C. It is forbidden to work in environment with combustible, explosive or corrosive situations.
This gantry crane is composed of bridge, L type support leg, crane travelling organ, trolley, electric equipment. The frame adopts box-type welding mechanism, the L type single leg is welding structure in order to increases the work space, and it is convenient for the transportation, installment and maintains. Crane travelling mechanism adopts separate drive.
The advanced design idea gives the crane light structure and excellent performance, at the same time narrows the hook operation distance in the maximum, and improves the space utilization rate effectively. So it can reduce your workshop investment costs and bring more investment returns.
Smooth, Fast Loading:The standard configuration of the crane are the trolley and crane both having stepless frequency conversion control system, with features of braked stably, accurate location, and reliable performance, which make traveling steady, positioning quick, solving the problem of swing of goods.
Safer, Reliable, Using Free Maintenance Design:The crane used the best technology in the whole process shows its superiority, especially in the frequent operations. The perfect braking system improves safety and reliability a lot, which can be adjusted by itself with dustproof design, and it can be used more than 1 million times. Hardening and polishing the tooth surface will make sure the crane operate without trouble.
Excellent Performance:As an important logistics equipment, if the crane is out of order, it will cause great damage. So our products always having high quality will be your best choice.
Gantry crane Control method:Cabin or remote control or pendent line with press button or both.
Gantry crane Design and construction rules:All the standards which is required for the crane is the Chinese standard.
Gantry crane Painting:Primer and finishing paint
Color: according to your demand.
Average thickness: about 100 microns.
