Overhead Crane Wheels Blocks Assembly Application Guide

Overhead Crane Wheels Block Assembly Product Introduction

Overhead crane wheels blocks assembly includes various wheel configurations categorized by rim form: double flange, single flange, and rimless crane wheels. The rim plays a critical role in guiding the overhead crane wheels blocks assembly and preventing derailment.

Typically, double flange overhead crane wheels blocks assembly are used for larger wheel diameters, while single flange overhead crane wheels blocks assembly are applied to smaller sizes. During installation, the rim is positioned on the outside of the crane rail. Rimless overhead crane wheels blocks assembly must be equipped with separate horizontal guide wheels to ensure proper guidance and prevent derailment—these guide components are often part of the crane end truck wheels or end carriage wheel assemblies.

According to tread type, overhead crane wheels blocks assembly are classified into cylindrical, tapered, and C-shaped drum wheels. The majority of overhead crane wheels blocks assembly and overhead trolley wheels utilize cylindrical or tapered treads, while C-shaped drum wheels are mostly used on LD single-girder overhead cranes running on the lower flange of I-beams. In trolley configurations, such as overhead crane trolley wheels, centrally driven trolleys typically have a conical active wheel and a cylindrical driven wheel; individually driven trolleys and all small trolley systems (e.g. hoist trolley wheels) use cylindrical treads. When tapered overhead crane wheels blocks assembly are used, they require curved-head tracks and are generally limited to configurations with two drive wheels and two driven wheels.

As for materials, forged crane wheels or forged steel crane wheels are recommended for mechanically driven systems exceeding 30 m/min and rated for medium-duty work or higher. These crane wheel assemblies should use materials not lower than ZG55 cast steel with surface quenching (flame or high-frequency), achieving a hardness of HB320–350 and a hardening depth of no less than 5 mm. For manually driven or low-speed machinery (under 30 m/min), cast iron eot crane wheels or crane rail wheels may be suitable, with hardness levels between HB180–240.

Our company offers a wide range of overhead crane wheels blocks assembly, crane end truck wheels, and customized crane wheel assemblies for various types of cranes, including gear overhead crane wheel assemblies, L block overhead crane wheel assemblies, and European overhead crane wheels. All components are produced using advanced welding and precision machining technologies, ensuring high structural integrity and dimensional accuracy. We also support non-standard customization to meet diverse project requirements and provide reliable, high-performance solutions.

European Overhead Crane Wheels Blocks Assembly

Manufacturing process:

Forged steel overhead crane wheels blocks assembly, forged crane wheels are mainly composed of four parts: axle, wheel, bearing box, and bearing. It is usually made of high-strength alloy steel and heat-treated to improve bearing capacity and wear resistance. In the manufacturing process, more overall boring and milling, and precision assembly processes are used, and some designs are directly connected to the reducer, which requires higher accuracy. Depending on the use scenario, the bearing and box structure are also different. In practical applications, the selection needs to be based on specific working conditions.

Features:

• The overhead crane wheels blocks assembly are light in weight, small in size, and easy to install.
• Forged wheels are mainly composed of four parts: axle, wheel, bearing box, and bearing.
• Due to the need to cooperate directly with the three-in-one reducer, there is no need to connect through a coupling, and the assembly accuracy is high.
• The bearings are imported NSK and SKF bearings, which have a long service life.

Application:

The European overhead crane wheel has been widely used in single girder overhead crane and double girder overhead crane, and has achieved good application results, which have been recognized by many users. Due to the excellent performance of such wheel sets, there will be more and more applications in the lifting industry.

L Block Overhead Crane Wheel Assembly

Manufacturing process:

The L block overhead crane is manufactured using an integral forging process. The key components include overhead crane wheels blocks assembly, and axles, all of which are made of high-strength 42CrMo alloy steel forgings to ensure excellent mechanical properties and fatigue resistance. The bearing configuration is SKF brand roller bearings (model 24040 CC/W33), which have good carrying capacity and operating stability. After the wheel surface is heat-treated, the surface hardness reaches 45-50 HRC, and the depth of the hardened layer reaches 6-8mm, which effectively improves the wear resistance. Usually, the weight of the whole set of overhead crane wheels blocks assembly is about 1800kg, the structure is stable, and it is suitable for heavy-duty working conditions. The surface spraying adopts one epoxy primer and two polyurethane topcoats, the total thickness is controlled at 80–120µm, and the coating scheme can also be customized according to customer needs, taking into account anti-corrosion and aesthetics.

Features:

• L-shaped cranes are often equipped with L block overhead crane wheel assembly, which is designed to withstand heavy-duty and high-frequency operating conditions.
• Its structure allows the installation error to be fine-tuned manually, thereby ensuring the accuracy and operating stability of the overall assembly.
