50 Or 10ton Hanger Bridge Crane

1.Main beam

1. The main beam is usually composed of two parallel steel beams connected by a crossbeam in the middle to form a solid frame structure. The design of the main beam takes into account the distribution of force, the strength and stiffness of the material to ensure that the load can be effectively carried when lifting heavy objects.

2. The main beam generally uses high-strength steel (such as Q235 or Q345) with excellent tensile and bending resistance. The choice of material directly affects the load-bearing capacity and service life of the main beam.

3. The size and specifications of the main beam are determined according to the design parameters and application requirements of the crane, and usually consider factors such as lifting capacity, span and lifting height. Detailed mechanical analysis is required during design to ensure the safety and stability of the main beam.

4. The main beam needs to be accurately installed during the assembly process of the crane to ensure the coordination of various components. After installation, static and dynamic tests are required to verify its load-bearing capacity and stability. As the core component of the crane, the main beam needs to be inspected and maintained regularly, including weld inspection, surface anti-corrosion treatment and structural integrity assessment to ensure its long-term stable operation. The design and manufacture of the main beam must comply with national and industry standards and be equipped with necessary safety devices (such as limit switches, overload protection devices, etc.) to ensure safety during operation.

Lifting System

1. Hoisting mechanism

The hoisting system mainly consists of a motor, a reducer, a drum, a hook (or other slings) and a wire rope. The motor provides power, reduces the speed and increases the torque through the reducer, and the drum is responsible for retracting and releasing the wire rope.

2. Motor

The hoisting system usually uses a three-phase asynchronous motor with high power and stability. The selection of the motor depends on the lifting capacity and operating speed requirements of the crane.

3. Reducer

The reducer is used to reduce the speed of the motor and increase the output torque. Common types include gear reducers and worm reducers. Choose the appropriate model according to actual needs.

4. Drum

The drum is a component used to retract and release the wire rope. It is usually made of high-strength steel to ensure stable operation under high loads. The diameter and design of the drum will affect the operation and durability of the wire rope.

 

3.End carriage

1. Structural design

The end beam is usually a horizontal beam structure, which is connected to the main beam vertically to form a stable frame. Each end beam is equipped with a wheel group to support the movement of the crane on the track. The design of the end beam should take into account strength and rigidity to ensure stability when loaded.

2. Material selection

The end beam generally uses high-strength steel (such as Q235 or Q345) to ensure its load-bearing capacity and bending resistance. The choice of material directly affects the service life and safety of the end beam.

Reducer: Converts the high speed of the motor into a suitable low-speed high-torque output to drive the wheels.

Wheels: Contact the track, carry the weight of the crane and allow it to move smoothly.

Underframe: Supports the entire crane mechanism and is connected to the main beam.

2. Working principle

The crane mechanism drives the reducer through the motor, and the reducer transmits power to the wheels, pushing the crane forward and backward on the track. The control system can adjust the start, stop and running speed of the motor to achieve precise control.

5.Trolley travelling mechanism

1. Working principle

The trolley running mechanism drives the reducer through the motor, and the reducer transmits power to the wheels to push the trolley forward and backward on the main beam. The control system can adjust the start and stop and running speed of the motor to achieve precise control of the hoist.

2. Control method

Emergency stop device: in an emergency, the operator can quickly stop the movement of the trolley.

6.Crane wheel

1. Material selection

The wheels are generally made of high-strength alloy steel or cast iron to ensure their strength and wear resistance under high load conditions. The choice of materials directly affects the service life and load-bearing capacity of the wheels.

2. Working principle

The wheels carry the weight of the crane and provide stable support by contacting the track. Driven by the motor, the wheels rotate and push the entire crane along the track. Good contact and friction ensure the safe and stable operation of the crane.

3. Design requirements

The design of the wheels needs to consider multiple factors:

Carrying capacity: According to the maximum load of the crane, the wheels need to have sufficient carrying capacity.

Hook body: the main load-bearing part, usually made of high-strength steel, and the shape is designed to ensure the stability of the heavy object.

Hanging ring: used to connect the lifting wire rope or sling, which is convenient for connecting with the heavy object.

Safety lock: prevents the hanging object from accidentally falling off during the lifting process and increases safety.

2. Material selection

The hook generally uses alloy steel or special alloy materials to provide sufficient strength and toughness. The choice of materials directly affects the load-bearing capacity and durability of the hook.

3. Working principle

During the lifting operation, the hook is connected to the lifting wire rope through the hanging ring, and the hook body safely hangs the heavy object. When the lifting system is working, the hook lifts the heavy object through the wire rope to complete the handling task.

Motor
