Hoister Gantry Crane

Hoister Gantry Crane is a kind of lifting equipment widely used in industrial production and warehousing, mainly used for lifting and transporting heavy objects. The main beam of this crane adopts box-type or I-shaped structure, which has good load-bearing capacity and rigidity. The secondary beam is used to support the main beam and enhance the stability of the structure. The crane wheel is usually made of high-strength material to ensure smooth operation on the track. The electric hoist is the core part of the lifting equipment, which is used to lift and lower the goods. The gantry consists of columns and beams to support the overall structure of the crane.

The Hoister Gantry Crane moves on the main beam through the electric hoist to achieve the lifting, movement and placement of goods. The operator operates through the console or remote control device.

3. The single-beam design makes the equipment occupy a small area and is suitable for small working environments. This crane is flexible and can adjust the working range and height according to needs. Compared with double-beam cranes, single-beam cranes are lower in cost and simple to maintain. Equipped with a modern control system, the operation is intuitive and easy to learn.

1.Main beam

1) The main beam is usually made of high-strength steel (such as steel plates, I-beams, box-shaped steel, etc.) to ensure its load-bearing capacity and resistance to bending and torsion. Common shapes include I-beams and box-shaped beams. The I-beam has a simple structure and is suitable for lighter loads; while the box-shaped beam has better bending and torsion resistance due to its closed structure and is suitable for heavy load conditions.

2) The main beam is mainly responsible for bearing the heavy objects and dynamic loads generated by the crane during operation. The lifting load is transferred to the ground through the crane's supporting structure (such as columns), thereby achieving safe lifting and movement of goods. The electric hoist installed on the main beam slides above it, and the main beam provides a moving track to ensure the smooth operation of the hoist.

3) The beam must have sufficient strength and rigidity to withstand the rated load and possible impact loads, ensuring that it does not deform or break under various working conditions. The design of the main beam needs to ensure the stability of the crane during operation to avoid tilting or tipping caused by unbalanced loads or dynamic loads. Try to reduce the deadweight of the main beam as much as possible to improve the working efficiency of the crane and save energy, while ensuring sufficient carrying capacity.

 

 

Lifting System

1) Components

The lifting system mainly consists of the following parts:

Electric hoist: The core of the lifting system, responsible for lifting and lowering the cargo. Depending on the design of the crane, the electric hoist can be fixed or mobile.

Main beam: The electric hoist is installed on the main beam, providing a sliding track to support the movement of the hoist.

Lifting mechanism: Usually composed of a motor, a reducer, a drum and a lifting wire rope. The motor drives the reducer, which in turn drives the drum to wind or release the wire rope, thereby achieving the lifting and lowering of the cargo.

Wire rope: Used to connect the electric hoist and the cargo to ensure the safety of the cargo during the lifting process.

2) Working principle

The working principle of the lifting system is as follows:

When the operator starts the electric hoist, the motor drives the reducer to rotate, thereby driving the drum to rotate.

The wire rope on the drum is rolled up or released as it rotates, and the cargo connected to it is lifted or lowered.

By controlling the lifting speed and position of the electric hoist, the operator can accurately control the movement of the cargo.

 

3.End carriage

1) The end beam of a Hoister Gantry Crane is an important part of the crane structure, which plays the role of connecting the main beam and the crane column, supporting the overall structure of the crane and ensuring the stable operation of the equipment.

2) The end beam is generally a rectangular or box-shaped structure, usually welded from steel plates or I-beams to provide the necessary strength and stability. The end beam is connected to the main beam and column by bolts or welding to form an integral structure. Wheel rails are usually installed on the end beam to provide a running path for the crane wheels to ensure smooth movement of the equipment during operation.

3) The end beam plays a supporting and bearing role in the overall structure of the crane, ensuring the stability of the crane during operation. The end beam transfers the load of the main beam and column to the ground, ensuring that the crane does not tilt or deform when lifting and moving heavy objects. The design of the end beam ensures the smooth travel of the crane on the track and reduces vibration and noise during operation.

 

 

 

4.Crane travelling mechanism

1) Basic structure

Crane frame: The main structure of the crane running mechanism, usually welded from steel, with strong load-bearing capacity and rigidity. Electric hoists and other related components are installed on the crane frame.

Wheels: Multiple wheels are installed at the bottom of the crane and move along the track. The wheels are usually made of high-strength materials to ensure smooth operation on the track.

Motor: Used to drive the operation of the crane, usually connected to the reducer, and the movement of the crane is achieved by controlling the rotation of the motor.

2) Working principle

The working principle of the crane running mechanism is as follows:

When the operator starts the motor, the motor drives the reducer to rotate. The reducer drives the wheels through the transmission device to move the crane on the track. The operator controls the movement direction and speed of the crane through the console or remote control to transport the goods to the desired location.

5.Trolley travelling mechanism

1) Basic structure

Trolley frame: The main structure of the trolley, usually welded from steel, is designed to ensure that it has sufficient strength and rigidity to carry the weight of the electric hoist and cargo.

Wheels: The bottom of the trolley is equipped with multiple wheels that can move along the track of the main beam. The wheels are usually made of high-strength materials to ensure stability during operation.

Electric hoist: The trolley is usually equipped with an electric hoist, which is used to lift and lower cargo and is the core part of the lifting system.

2) Maintenance and inspection

Regular maintenance of the trolley operating mechanism is the key to ensure its safety and efficiency, including:

Check the operating status of the motor and reducer to ensure normal operation, and lubricate and clean it when necessary.

Check the wear of the wheels and tracks to ensure that there are no obstacles to maintain smooth operation.

Check the electrical system to ensure that the control system and safety devices are working properly.

6.Crane wheel

1) The wheels are usually made of high-strength steel with good load-bearing capacity and wear resistance to meet the operating requirements of the crane under various working conditions. The wheel profile design is usually concave or flat to match the track, provide a stable contact surface, and reduce wear and noise during operation.

2) The wheels are responsible for supporting the weight and load of the crane to ensure stability and safety during movement. Guide the crane to run smoothly on the track to ensure that the equipment does not deviate from the track during operation. High-quality wheels can effectively reduce vibration during operation and improve the smoothness and comfort of operation.

3) The wheels support the crane to run on the track by contacting the track. When the motor starts, it drives the movement of the trolley or car, and the wheels rotate on the track to achieve the longitudinal movement of the crane.

7.Crane Hook

1) The hook is usually made of high-strength alloy steel with good tensile strength and wear resistance to ensure safety under heavy loads. The hook is generally in the shape of a curved hook and is divided into two forms: single hook and double hook. Single hook is used for lighter loads, and double hook is used for heavier loads and operations that require higher stability.

2) The main function of the hook is to carry and suspend cargo and transfer the load to the crane's lifting system. The hook can be connected to various lifting devices (such as chains, wire ropes, slings, etc.) to facilitate the lifting and movement of different types of cargo. Good design and structure can ensure the safety of cargo during the lifting process and reduce the occurrence of accidents.

3) The hook is connected to the lifting mechanism through the wire rope or chain of the electric hoist. When the lifting system is started, the hook moves with the rise and fall of the electric hoist to achieve the lifting and placement of the cargo.

Motor

1) Working principle

When the operator starts the motor through the control system, the rotation of the motor will be transmitted to the lifting mechanism or operating mechanism through the reducer. The rotation of the motor causes the reducer to output appropriate torque, thereby driving the movement of the crane to complete the lifting and movement of the goods.

2) Maintenance and inspection

Regular inspection: Regularly check the operating status of the motor, including bearings, wiring and cooling systems, to ensure its normal operation.

Lubrication maintenance: For the moving parts such as bearings of the motor, lubricate them regularly to reduce wear.

Electrical system inspection: Regularly check the electrical connection and insulation of the motor to ensure safety and reliability.
