1.Main beam

1) The main beam of the outdoor gantry crane is a critical component, typically designed to support the load being lifted. It's usually made from high-strength steel to provide the necessary strength and stability.It's typically made from robust materials like steel to ensure strength and durability, especially since it will be exposed to outdoor conditions. The design usually involves a box or I-beam structure to provide the necessary rigidity while minimizing weight.

The main beam is usually made of high-strength steel with excellent mechanical properties and good fatigue resistance. The selection of materials should take into account the stress and load changes that the main beam will bear during long-term work, including the weight of the crane itself and any additional loads during operation, to ensure the safety and durability of the double-beam gantry crane. Commonly used steels include high-quality low-carbon steel or alloy steel such as Q235 and Q345, which have good weldability and processability.

3) The main beam of the outdoor gantry crane has secure connection points for other components and is welded using an automatic or semi-automatic welding process to ensure the quality and strength of the welds. The main beam and other parts also need to be inspected to ensure that there are no cracks or defects inside. The size, length and shape of the main beam must be very precise. The length of the beam affects its structural integrity and ability to support loads without excessive deflection. Strict dimensional measurements and controls are carried out during the manufacturing process to ensure the straightness and lateral rigidity of the main beam, thereby ensuring the smooth installation and operation of the crane.

Lifting System

Motor: The outdoor gantry crane typically uses a motor to drive its lifting mechanism. The motor can be electric or diesel-powered, depending on the crane's design and application.The motor accurately controls the lifting speed of the cargo through the control system.

Reducer: The outdoor gantry crane reducer is a mechanical component that reduces the speed of the motor's output while increasing its torque. This is crucial for lifting heavy loads safely and efficiently.The reducer must be rated for the maximum load the crane will handle, ensuring reliable performance under heavy conditions. Since these cranes are used outdoors, reducers often come with protective coatings or enclosures to resist corrosion and weather-related damage.Regular maintenance is essential to ensure the reducer operates smoothly. This may involve lubrication, checking for wear and tear, and replacing any worn components.

Drum: The drum is used to wind and unwind a wire rope or cable, allowing for vertical movement of the load. It retracts and releases the wire rope by rotating to directly control the lifting and lowering of the hook or other slings. The size and material of the drum need to be designed according to the lifting weight and the specifications of the wire rope.

Wire rope: Wire rope is made from multiple strands of steel wire twisted together, providing high tensile strength.The construction allows the rope to bend and move easily, which is necessary for lifting and lowering loads.Wire ropes are designed to resist abrasion, corrosion, and fatigue, making them suitable for outdoor environments. Regular inspection and maintenance of wire ropes are crucial to ensure safe operation and prevent accidents.

Pulley block: The pulley block is a crucial component of the crane's lifting mechanism, allowing for the efficient transfer of loads by redirecting the lifting force.

Lifting device: The lifting device is the part that comes into direct contact with the goods, usually a hook or electromagnetic suction cup, grab, etc. Designed for outdoor use, these lifting devices allow for mobility and versatility in a variety of applications, such as shipping yards, construction sites, and warehouses.

3.End carriage

1) The end beam is usually a box-type structure or an I-beam structure with high strength and rigidity. The box-type end beam is welded from steel plates and can effectively resist the torque and bending moment generated during the operation of the crane. A wheel set is installed on the end beam, which consists of a driving wheel and a driven wheel, responsible for the longitudinal movement of the crane along the track. The wheels are usually made of wear-resistant alloy steel or cast steel, with high load-bearing capacity and wear resistance.

2) The end beam is connected to the main beam by bolts or welding to form a complete bridge structure to ensure overall stability. The connection between the end beam and the main beam requires high precision to ensure the smooth operation of the crane and the integrity of the structure. The end beam is mainly used to carry the weight of the crane bridge and transfer it to the track on the ground through the wheels. At the same time, it also supports and stabilizes the main beam so that it can withstand various forces during the lifting process.

3) The driving wheel on the end beam is responsible for the travel of the bridge, pushing the crane to move forward and backward on the track to realize material transportation in space. The drive system can be equipped with a variable frequency speed regulation device to accurately control the movement speed of the crane. By installing limit switches or sensors, the end beam can automatically stop when the crane reaches a predetermined position to prevent collision or deviation from the track.

 

4.Crane travelling mechanism

Power transmission: The motor transmits power to the wheel set through the reducer, and the wheels roll on the track to achieve the forward and backward movement of the crane. The design of the reducer allows the crane to run smoothly under low speed and high torque conditions.

Control system: The crane traveling mechanism of modern cranes is usually equipped with advanced control systems, including frequency converters, PLCs, etc., to achieve precise speed regulation and position control.

2) Functions of the crane operating mechanism

Horizontal movement: The crane operating mechanism is responsible for the horizontal movement of the crane in the working area and supports the operation of the lifting crane on the main beam.

Load distribution: Through the configuration of multiple wheels, the load can be evenly distributed on the track, reducing the pressure of the unit track and reducing track deformation and wear.

Positioning accuracy: The crane traveling mechanism can accurately stop at the specified position to ensure the safety and accuracy of the lifting operation.

5.Trolley travelling mechanism

1) Structural composition

The trolley itself is a structure that holds the hoisting mechanism and can move horizontally along the beam.The trolley is equipped with wheels that run on rails mounted on the outdoor gantry crane's beams. The wheels can be designed for easy rolling, often using ball bearings to reduce friction.The trolley is usually powered by an electric motor or sometimes a manual system. The motor drives the wheels, enabling the trolley to travel back and forth along the crane's beam.

2) Function of the trolley operating mechanism

The main function of the trolley operating mechanism is to enable the lifting trolley to move laterally on the main beam, thereby achieving accurate positioning and handling of the goods.The operator controls the travelling mechanism through a remote control or a cabin on the crane.

6.Crane wheel

Wheels are typically designed to roll smoothly on tracks, with features that minimize friction and allow for easy maneuvering. They are usually made of durable materials, such as steel or high-strength composites, to withstand heavy loads and environmental wear. The size of the wheel affects the stability and load capacity of the crane. Larger wheels distribute weight more efficiently. Larger wheels distribute weight more efficiently. Crane wheels use high-quality bearings to ensure smooth operation and reduce maintenance requirements. The wheels of outdoor cranes should be designed to resist rust, corrosion, and other environmental factors.

7.Crane Hook

1) The crane hook of an outdoor gantry crane is a critical component designed to lift and maneuver heavy loads. It is typically made of high-strength steel to withstand significant weight and stress. The hook is often equipped with safety features, such as a latch or locking mechanism, to prevent accidental release of the load.Outdoor gantry cranes may have different types of hooks depending on their specific application.

2) The main function of the hook is to safely grab and lift various materials and ensure that the material does not fall off during movement. The design of the hook allows quick and easy connection with different types of hoists (such as lifting rings, grabs, magnets, etc.), improving the flexibility of the operation.

Motor

The Motor's production of outdoor gantry cranes involves designing and manufacturing cranes that are specifically built for outdoor use. These cranes typically feature a robust structure to withstand various weather conditions and can handle heavy loads.

The motor powers the hoist, which raises and lowers the load. It typically drives a drum or a set of pulleys that wind or unwind a cable or chain connected to the load. The motor facilitates the lateral movement of the gantry crane along its rails. This allows the crane to position itself over the load and transport it horizontally.In some designs, a motor may also be responsible for rotating the hoist or the crane's superstructure, enabling precise placement of the load.Motors can be equipped with variable speed drives to allow operators to control the speed of lifting and traveling, enhancing safety and efficiency. Modern motors often come with built-in safety features, such as overload protection and emergency stop functions, to prevent accidents and equipment damage.

3) The motor of outdoor grantry crane is responsible for driving the operation of the trolley and the car, enabling the crane to move on the track for lifting and positioning of materials.
