What is a gantry crane? Speaking of gantry crane definition, as the deformation of the overhead cranes, it is a gantry lifting equipment that used in different working occasions, such as container port, shipyards, dock, offshore, etc. For its appearance and structure looks like a portal or a gate, it has been called gantry crane.
Basic Component and Structure of Gantry Crane
What is a gantry crane? A crane gantry mainly consists of bridge, supporting legs, electric control system, crane travelling system, trolley travel mechanism, lifting mechanism, cab, etc.
Basic Frame of A Gantry Crane
The basic frame of gantries such as main beam and supporting legs are composed of box-shaped or truss structure. Different structures are of their own advantages. Box-shaped crane is for the advantages of strong-rigidity and easy-maintenance, while the truss-shaped structure is of strong wind-resistance ability but light lifting capacity. Different designs of gantry cranes are used on different work occasions.
Electric Control System
Electric control system for gantry crane mainly refers to gear reducer, brakes, electric motor, etc. The three of them control the travelling of the crane and trolley machines.
Crane and Trolley Travelling Systems
Crane travelling system and trolley travel mechanisms can achieve running once energized. And there are three power supply mode of gantries, cable reels supply, diesel generators and sliding wires supply.
We adopt advanced level wheels in the crane. All wheels are of compact structure and smooth moving, which ensure the smooth operation and high-safety of the whole set.
Settings Of the Cab
Ground operation and air operation are two forms of gantry crane. In order to decrease the labor intensity and guarantee safety of the operators, it is necessary to install a cab on the crane, besides, operators control in the cab can also increase the accuracy of the goods and materials handling. Cab control features wider view and safer operation.
