L Leg Single Girder Gantry Crane
Crab Trolley & Electric Hoist Gantry Crane Designs

The single girder gantry crane with "L"shaped supporting legs and electric hoist or electric hoist trolley is a light and moderate duty gantry crane, used for general material handling in the open air, such as open freight yard, railroad terminals, factories and indoor applications such as warehouses and workshops, etc. With the obvious features of " L" shape legs, the hoist trolley gantry crane is a good choice for long and large objects and items, such as steel pipe and concrete blocks, etc. Compared to the double girder gantry crane, L type single girder gantry crane is able to load and unload objects with capacity of 5 ton to 32 ton, featured as wider space for long objects, lower crane height when the lifting height is fixed, lighter self-weight and lower crane cost, etc.

Parameters of L type single girder gantry crane

The L-type electric hoist gantry crane is an essential lifting crane for increasing working efficiency, safety and productivity. The trolley gantry crane is capable of handling heavy loads with capacity of 5 tons to 32 tons, crane span of 10-35 meters, lifting height of 6-30 meters, and also customized gantry crane designs are available. The main parameters of the L type single girder beam gantry cranes with electric hoist are presented for your reference.

Types & Configurations

L type single girder gantry crane is a type of rail traveling light and moderate duty gantry crane, worked with different types of wire rope hoists, usually the CD MD electric hoists for generally material handling. According to the shape, the L shape electric hoist gantry cranes can be grouped into:

MH L type single girder gantry crane with electric hoists suspended under the main girder, which can be box girder design and truss girder design. The box girder electric hoist gantry cranes is featured of strong structure and easy fabrication while the truss crane is light in dead weight and strong in wind resistance.

MHLP type single girder gantry crane with electric hoist trolley placed on the top but aside of the box shaped main girder is a partial hanging gantry crane, with features of small size and light duty, especial for handling steel pipes, girders, or other long objects , widely used in steel plant, concrete girder yard.

Structures and components

The L type single girder gantry crane is consisted of gantry bridge, L shaped support leg, crane travelling mechanism, electric hoist or electric hoist trolley, electric equipment, and safety devices, etc. The L shaped leg design increases the work space and makes the single girder electric hoist crane convenient for transportation, installment and maintenance. .

Unlike A frame gantry crane or U frame gantry crane which is supported on two legs at each side, the L type single girder gantry crane is designed to stand on one L-shaped leg at each side for the convenience of handling long pieces of objects or loads like steel pipe and concrete girder, etc. The L-type single girder gantry crane is specifically designed for light to moderate service that can be installed with two electric wire rope hoists and hooks for long objects handling with better stability and high safety during lifting operation.It is also ideal solution for tilting operations.

Features of L type electric hoist gantry crane

• With L-shaped structure, the electric hoist gantry crane is much easier to handle long objects or oversize loads through the legs.
• With sturdy construction,the electric hoist gantry crane can withstand severe working environments with working life.
• Components Standardization and Modular Design makes the single girder gantry crane easy to assembly and disassembly.
• Adopting soft start, the hoist crane is guaranteed to be stable and smooth during operation.
• The single beam hoist crane requires little maintenance and less operating cost.

Options

The single girder hoist gantry cranes are provided with various options and accessories for you to selected from, including:

• Rated load capacity of single girder gantry crane with electric hoist: from 5 ton to 32 ton
• Gantry frame design of gantry crane: box shaped gantry girder design / Truss gantry girder design
• Hoisting mechanism of electric hoist gantry crane: electric hoist or electric hoist trolley
• Crane control of electric hoist crane: pendant control, wireless remote control or driver's cabin control

Applications

L type wire rope hoist gantry crane designed with L shaped gantry legs and powerful electric hoist and hoist trolley, equipped with crane hook or electromagnetic chuck, or crane grab for various material handling, especially for long objects or items handling, with capacity of 5 ton to 32 ton . Generally. L type wire rope hoist gantry cranes are widely adopted in the two conditions for general material handling:

Outdoor applications - where lifting equipment are needed without the cost of a building or any supporting steel structure

Indoor applications - where existing structures of the workshop is not suitable to install overhead bridge cranes, and where additional supporting steel structure would result in a loss of floor space. The single beam gantry crane can be designed with cantilevers to enable the handling of loads outside the rail centers.

However, it is prohibited to be used in dangerous environments, such as, high temperature, flammable, explosive and corrosion environment, etc., where specially designed single girder gantry crane are needed. Please contact us to get more information on the hazardous application material handling crane.
