New electric single girder crane

This crane model is based on the introduction and mastery of foreign advanced technology, based on the theory of modular design, using modern computer technology as a means, introducing optimized design methods and design reliability, and introducing imported configurations, new materials and new processes. The finished new crane is lightweight, versatile, energy efficient, environmentally friendly, maintenance free and high tech. The main beam and end beam are welded box beam structures, the bottom flange serves as the running part of the electric hoist. The main beam and end beam are connected with high-strength bolts to facilitate transportation and installation on site. The lifting mechanism uses a new electric hoist, which is compact and easy to maintain. .

It has a C-shaped design with the motor and drum arranged in parallel. The motor, gearbox, drum and lift limit switch are integrated into the design. All major transmission components are exposed, making installation and maintenance easy. The body adopts a rod-shaped frame structure, that is, the gearbox and the electrical control unit are connected by a round rod, forming the main body of the lift. Simply replace round bars of different lengths to adapt to the needs of different drum lengths and different lifting heights. The hanging trolley is side shaped with low building height and controlled by frequency converter.

The overall optimized design of the moving mechanism includes three-in-one drive device and variable frequency speed control. It has the advantages of compact structure, low noise and maintenance-free operation.

The two speed squirrel cage motor is used for lifting and the variable speed motor is used to operate large and small vehicles.

The electrical connection uses heavy-duty, international standard aviation plugs with IP65 protection, ensuring quick connection and disconnection, as well as a reliable connection.

The crane is operated by a manual door located on the ground. The manual door is separated from the electric winch and suspended from the main beam through a guide system for free movement.
