Crane Wheels

The DRS wheel block system is a modular drive/load-bearing wheel block solution commonly used in suspension cranes and other material handling equipment. It is particularly suitable for industrial occasions with high requirements for operating stability, compactness and load-bearing capacity.

The following are the main features, structural composition and application of the DRS wheel block system in suspension cranes:

Introduction to the DRS wheel block system

DRS is the abbreviation of "Demag Running System", which was first proposed and widely used by Demag in Germany. This system has become a standardized solution in the field of industrial lifting and is suitable for rail-type operating mechanisms such as bridge cranes, gantry cranes, suspension cranes, automated stackers, turntables, rail transport vehicles, etc.

Structural composition of the DRS wheel block system

Wheel body 

Material: high-strength cast steel or forged steel, the surface can be hardened to improve wear resistance.

Form: optional single-sided guide wheel, double-sided guide wheel or rimless wheel, adapted to different track requirements

Bearing unit

Enclosed rolling bearing, maintenance-free or low-maintenance.

High precision, strong load-bearing capacity, smooth operation.

Housing (wheel set housing)

Strong welded or cast structure for mounting axles and connecting external frames.

Multi-faceted mounting holes for easy multi-angle positioning and installation.

Sealing system

Multi-layer sealing, dust-proof, waterproof, and oil-proof, and improves service life.

Drive system (optional)

Can be combined with reducer and motor to form a drive wheel set to achieve active operation function.

Main features of DRS wheel set

Modular design: easy to assemble and replace quickly, shortening installation time.

Strong load-bearing capacity: a single set of wheels can carry from 2.75 tons to 40 tons.

Wide adaptability: can be used for a variety of track structures, including I-beams, flat rails, angle steels, etc.

Smooth operation and low noise: high-precision manufacturing ensures smooth rolling of the wheels on the track.

Easy maintenance: replacing wheels or bearings does not require disassembly of the entire equipment.

Application of DRS wheels in suspension cranes

Suspension cranes are usually installed on I-beam tracks, and the DRS wheelset system can be used as the core component of the operating mechanism. Application advantages include:

Compact design: suitable for places with limited plant space;

Flexible installation: can be adapted to cranes with different spans and different lifting weights;

High reliability: improve the stability and service life of the whole machine;

Customization feasibility: can be customized according to track type, running speed, and load capacity.

If you need to customize the wheelset for the suspension crane system to reduce noise or run on special tracks, Philson can provide professional customized solutions based on track size, load requirements, and drive mode. Welcome to contact us!
