Gantry Crane Wheels

1.Function
1)Support the entire weight of the gantry crane, including its own structure and the lifted load.
2)Enable the crane to move horizontally along the runway rails or tracks.
3)Transmit the driving force from motors to facilitate smooth travel.
4)Withstand side thrusts, vertical loads, and impacts during crane operations.

2.Wheel Drive System
1)Driven Wheels (Active Wheels):
Connected to motors and gearboxes.
Provide the motion to the entire gantry crane.
2)Idle Wheels (Passive Wheels):
Roll freely, helping to balance the load and maintain stability.
In a typical gantry crane, at least two wheels are powered by motors, and the rest are idle.

3.Gantry crane wheels are essential load-bearing and mobility components used in gantry cranes for smooth and precise traveling along rail tracks. Designed to support heavy-duty operations, these wheels are manufactured with high-strength steel and advanced heat-treatment processes to ensure durability, load capacity, and long service life under demanding industrial conditions.
4.These wheels are suitable for a wide range of applications, including container handling cranes, shipyard gantry cranes, rail-mounted cranes, and factory floor gantries.

The forged wheel production procedure typically involves the following steps:

1. Design: The wheel design is determined based on customer requirements, vehicle specifications, and engineering considerations.

2. Material selection: The wheel is usually made of high-quality aluminum alloy, which is chosen for its strength and durability.

3. Forging: The forging process involves heating the aluminum alloy to a precise temperature and then using a high-pressure press to shape the material into the desired wheel form. This process creates a dense grain structure that enhances the wheel's strength and reliability.

4. Machining: The forged wheel is then machined on a CNC lathe or milling machine to create the final shape and dimensions. This step ensures that the wheel is precise and free of imperfections.

5. Heat treatment: The wheel is then heat-treated to further enhance its mechanical properties and durability.

6. Surface finishing: The wheel is typically polished, painted, or powder-coated to enhance its appearance and protect it from corrosion or wear.

7. Quality control: The wheel is thoroughly inspected for any defects or irregularities, and rigorous testing is conducted to ensure that it meets all necessary quality standards and specifications.

8. Packaging and shipment: Once the wheel has been fully inspected, it is carefully packaged and shipped to the customer or distributor.

The company has installed an intelligent equipment management platform, and has installed 310 sets (sets) of handling and welding robots. After the completion of the plan, there will be more than 500 sets (sets), and the equipment networking rate will reach 95%. 32 welding lines have been put into use, 50 are planned to be installed, and the automation rate of the entire product line has reached.
