Overhead Crane Wheels Block Assembly

Advantages

No bearing box – The bearing is directly installed inside the wheel, resulting in a simple structure.

High cost‑effectiveness – Affordable and reliable.

Strong part interchangeability – Easy to source replacement components.

Disadvantages

Rail biting or derailment adjustment – Adjusting the crane wheel when it bites the rail or derails is not convenient.

Wheel replacement and disassembly – Replacing and disassembling the hoist wheel can be quite troublesome.

L Block Crane Wheel Assembly

Angular bearing housing structure – The L block crane wheel assembly typically features an angular bearing housing design, making it suitable for heavy loads and frequent operating conditions.

Adjustable for installation errors – Installation errors in the wheel set can be manually adjusted and compensated for, ensuring high assembly precision.

45°Split Bearing Box Crane Wheel Assembly

Reduced contact stress – The bearing housing is designed with a 45‑degree split, effectively reducing contact stress between the wheel and the rail, thereby extending the wheel's service life.

Even stress distribution – The 45‑degree split design ensures more uniform stress distribution across the wheel, reducing local stress concentrations and enhancing the wheel's durability and stability.

Adaptable to harsh conditions – This design allows stable operation in various complex environments, including high temperatures, high humidity, and dusty conditions.

Easy disassembly and replacement – The 45‑degree split design also makes the wheel easier to disassemble and replace, reducing maintenance time and costs.

Round Bearing Box Crane Wheel Assembly (European Type)

Compact structure & even load distribution – The round bearing housing has a compact design that evenly distributes the load, reducing localized stress concentration.

High‑quality bearings – The bearing housing typically contains high‑quality self‑aligning roller bearings, which reduce operational friction and improve running smoothness.

Flexible design – Suitable for various installation methods, making it convenient to assemble with different types of lifting equipment.

Standardized mounting holes – The bearing housing usually comes with standardized mounting holes, offering strong versatility and ease of installation and maintenance.

Hoist Trolley Wheel Sets (cylindrical tread)

Cylindrical tread design – Commonly used in conjunction with H‑beams, box‑type load‑bearing beams, and other structures with flat bottom surfaces.

Reduced contact stress – The cylindrical tread design effectively reduces contact stress between the wheel and the track, enhancing the fatigue resistance of metal components.

Quenching heat treatment – The wheel surface is treated with a quenching heat treatment process to further increase the load‑bearing capacity of the wheel set.

Hoist Trolley Wheel Sets(conical tread)

Parameters:

Conical Tread Wheel Assembly – Features

Conical tread design – Suitable for use with I‑beams, welded box beams with I‑beam flanges, and other load‑bearing components that have a certain degree of slope on the lower flange.

Large contact area – The wheel tread has a large contact area with the track flange, resulting in low static wheel pressure concentration and strong load‑bearing capacity.

Quenching heat treatment – The working surface of the wheel is treated with a quenching heat treatment process, increasing the wheel's hardness and wear resistance.
