Structure & Composition

The full gantry double girder gantry crane with truss gantry design is consisted of the steel structure, the crane traveling system, crane trolley or electric hoist , electric parts and crane control system, and other crane parts and components, etc.The metal structure of truss beams double girder gantry crane mainly consists of the main beam with single girder or double girder design, end beam, supporting legs or out-triggers and end carriages. Truss girder gantry crane has lighter weight than box girder crane. The overall size of double girder gantry crane with truss gantry design steel structure is determined by the factors,including crane capacity, span length, lifting height, cantilever length, wheelbase of trolley and crane travelling mechanism,etc. .

• Steel structure:The steel frame structure of double girder gantry crane with truss gantry design is welded with Angle steel or Steel bar to make the gantry crane more suitable for windy application with advantages of light dead weight, high rigidity and high wind proof ability. . Connected with unique steel nails, the structure of double girder gantry crane with truss gantry design is not only strong, but also easy to install, assemble and disassemble when moving to a new site.
• Truss girder:Truss gantry girder has two types of designs, the single girder crane design and double girder crane design, which can meet your need for light-duty and heavy-duty material handling. Besides,, the metal structure of the gantry crane girder can be designed with or without cantilevers.
• Supporting legs: the double girder gantry crane with truss gantry design is usually supported on two rigid legs. However, when the length of double girder gantry crane with truss gantry design span is larger than 35m, the truss beams double girder gantry crane will be engineered to stand up on one rigid leg and one flexible leg.
• Crane frame traveling system: the frame structure of double girder gantry crane with truss gantry design is travelling on and along the installed track or rail on the ground for the transportation of loads
• Lifting system: lifting mechanism of truss beams double girder gantry crane is an electric winch trolley or electric hoist, equipped with hook and other lifting devices for loads hoisting.
• Crane control system: Ground crane control and driver cabinet control, etc.

Single cantilever & Double cantilever double girder gantry crane with truss gantry design

In terms of cantilever design of gantry frame, double girder gantry crane with truss gantry design can be grouped into

• Double Cantilever truss beams double girder gantry crane - most frequently used structure, which can take full use of the endurance capacity of crane structure and application space reasonably.
• Single cantilever truss beams double girder gantry crane - Used when the application space is limited.
• truss beams double girder gantry crane with no cantilever - the main girder has no cantilever with the hoisting trolley or winch trolley running within the crane span

Safety feature

• Loss of pressure fault phase protection -Electricity will be disconnected if the voltage is too low. The electricity will be disconnected when the phase is changed.
• Over voltage or over current protection -The electricity will be disconnected if the voltage is too high. The electricity will be disconnected if the current is too large.
• Overload limit switch-When the lift capacity exceeds the maximum rated lift capacity, the electricity is turned off, and the crane stops working.
• Weight limit-Observe the hook's reduction. There is a height restriction. If you reach this point, the hook will be unable to fall any farther.
• Fire limit -Keep an eye on Hook's up and down limit positions. Protect the hoist by avoiding over-incrementing and over-decrementing.
• Crane travel limit switch -Supervise crane travel and stop it if it exceeds the rated travel distance.

Benefits of employing truss beams double girder gantry crane

• With small windward area, the double girder gantry crane with truss gantry design is inborn with excellent wind resistance, an ideal lifting solution in heavy wind areas
• With truss structure and cantilever design, truss beams double girder gantry crane offers light dead weight and large hook coverage.
• double girder gantry crane with truss gantry design is easy to be operated, installed and maintained with safety and convenience.
