Description

Technical Field

[0001] The utility model relates to the technical field of wheels for end beams of electric hoist single-beam and double-beam cranes, in particular to a wheel for end beams of electric hoist single-beam and double-beam cranes. Background Art

[0002] Among lifting equipment, electric hoist bridge cranes are widely used due to their compact size, light weight, and small wheel pressure. However, the disadvantage is that the traveling parts of this type of product, the wheel set, have many defects such as large size, heavy weight, small load-bearing capacity, inconvenient installation, and unsightly structure.

[0003] However, when assembling wheels on cranes now, due to the large friction between the wheels and the rails, the wheels need to be lubricated after being used for a period of time. Generally, lubricating oil is sprayed on the wheel surface manually to reduce the friction between the wheels and the rails and extend the service life of the wheels. However, the end beams are generally at high places and it is inconvenient to spray lubricating oil on the wheel surface. Therefore, there is a problem that the end beams are generally at high places and it is inconvenient to spray lubricating oil on the wheel surface. Moreover, when assembling wheels on cranes now, the wheels are prone to collision and friction with the inner wall of the rail. Excessive friction will cause damage to the wheels and cause losses, and new wheels need to be replaced. Moreover, the installation and replacement of wheel sets is troublesome, time-consuming and laborious. Therefore, there is a problem that the installation and replacement of wheel sets is troublesome, time-consuming and laborious. In summary, there are problems that the end beams are generally at high places and it is inconvenient to spray lubricating oil on the wheel surface and the installation and replacement of wheel sets is troublesome, time-consuming and laborious.
