L leg Single Girder Gantry Crane with Hoist Trolley

Overview of Single Girder Gantry Crane L Leg for Outdoor Use

The single girder electric trolley gantry crane is a mid-weight gantry crane with electric and crane hooks, as well as the obvious feature of "L" shape legs, which make the crane more convenient for handling cargo with long lengths, such as steel pipe, and so on.

L-type single girder gantry cranes are paired with hoist trolleys, which are a type of rail travelling mid-light crane. It is ideal for outdoor applications that require lifting capabilities without the expense of a building or any supporting steelwork. They are also appropriate for indoor applications where existing building structures are insufficient to support overhead cranes and additional supporting steelwork would result in a loss of floor area. It can be built with a cantilever on each or both end of main girder to allow for handling outside of the rail centers.

Components of electric hoist trolley gantry crane

Single girder gantry crane with hoist trolley is mainly consisted of bridge, L shape support leg, crane travelling system, electric trolley, and electric system, etc.

Advantages of electric hoist trolley gantry crane

• Inventive gantry structure, with unique gantry leg design
• Advanced technology, appealing appearance
• High working efficiency and safety High quality at a low cost
• High adaptability and broad applicability
• The L shape leg design saves more space for cargoes, is convenient for handling cargo of a long length, and can be transferred to another location.

Features of single girder hoist trolley gantry crane

• Box type gantry girder, L shape supporting legs with weld box structure, increases working space, and is easy to install and maintain;
• The hoist trolley power supply makes use of profiled rails, a safety slide line, and a cable conductive device system.
• Standardization, seriation, and generalization of components;
• Crane power can be supplied by a cable reel (left and right) or a sliding line (left and right).
• Good operation vision of cab equipped on the gantry crane to provide flexible and comfortable operation. Optional installation of fan, heater, cooler, air-conditions and intercom according to the customers' requirements;
• Customized based on the users' working environment needs, power source types, and other technical requirements. Furthermore, design and manufacturing span according to user requirements.

Comparison: L leg gantry vs. A frame double girder gantry crane

• The L type leg single girder gantry crane has a low deadweight, a light wheel load, and a dependable performance.
• The single girder hoist trolley crane is used for general loading and unloading, as well as lifting and handling tasks in open freight storage and along railways.
• When transporting long items over a span without space constraints, the L leg single girder gantry crane has structural advantages over the MG A frame double girder gantry crane.
• Furthermore, because of the structural characteristics of the L type leg crane, the height of the entire product is reduced, saving money in the case of a specific height. Under the same conditions, the weight is lighter and the wheel pressure is lower.
• Given certain lift height, the overall height of L leg single girder crane is reduced out of its structural features. As a result, the cost is lowered.

L shape suporting leg single girder gantry crane up to 32 ton

A frame double girder gantry crane with capacity up to 550 ton

Applications of electric trolley gantry crane

The electric hoist trolley single girder gantry crane is the best choice for outdoor material handling when no supporting building or steel work is available or when the supporting building is not suitable for supporting overhead crane.

They are widely used in cement plants, construction, electronics industries, warehouses, railways, food, papermaking, and engineering industries, among other places. It is not, however, permitted to be used in hazardous environments such as high temperatures, flammable, explosive, corrosion, and other environments, etc.

Warning: Overloading for all types of gantry crane is strictly forbidden.
