Universal all-rounder for cranes and systems

The SR wheel block programme is used in crane, trolley and systems building as well as in custom applications and special constructions. The SR wheel block comes in six different sizes for wheel loads from 5,000 kg to 30,000 kg.
Thanks to various mounting possibilities, the wheel block can be used universally and flexibly. Various custom versions are available for use under exceptional conditions. Optional guide rollers or a derailment protection device add to the safety of your system.

The SR wheel block programme is available in an explosion-proof version for zones 1, 2, 21 and 22.

Technology

Superior technology

The SR wheel block programme boasts superior technology. The low-maintenance components of the modular wheel block are optimally matched to each other. They guarantee constant performance, long service life and high efficiency. The SR wheel block stands out for its simple, universal and flexible assembly.
Housing
- High quality thanks to own, modern production
- Dimensional accuracy thanks to five-sided enclosure
- Graduated sizes for different wheel loads
- Optionally with buffer
Wheel
- Spheroidal graphite cast iron EN-GJS-700 (GGG70)
- Flange-guided on both sides
- Quiet run, reduced runway wear
- Low wear and strong thanks to self-lubrication
- Maintenance-free anti-friction bearing thanks to lifetime lubrication
Laufradwechsel
- Leichte Kontrolle der Spurkranzabnutzung
- Einfacher Wechsel des montierten Laufrads: nach Entfernen des Pufferflansches kann das Laufrad nach Abziehen der Lager und Lagerflansche nach vorne herausgezogen werden.
Guide rollers and derailment protection
- Applications: for extra wide rails, to reduce travelling resistance, to reduce skewing forces, to minimise runway wear
- Minimisation of cornering forces and wear
- Wheel design without flange, the opposite side is equipped with a derailment protection device.
- Larger rail widths possible
Drive
- Pole-changing travel motors
- Low-maintenance direct drive (vertical/horizontal) with torque support
- Optionally single or centralised drive or without drive
- Optionally with frequency-controlled motors
- Space-saving angle drive

Options and features

Although it is already first-class in its standard design, you can make the wheel block even safer, more economical and more convenient with a range of mechanical, electrical and electronic options. They simultaneously improve performance, prolong service life and make it possible to adapt the wheel block individually to specific requirements.
Here are some of the options frequently used.

Standard travel drive vertical/horizontal

The travel drive is mounted to the wheel block ex works vertically with a torque support. The standard travel drive can optionally also be mounted to the wheel block horizontally with a torque support.
Angle travel drive vertical/horizontal

The angle travel drive saves valuable space and guarantees optimal accessibility for maintenance work even in confined spaces. It is used, for example, in portal cranes or in storage technology when passing through recesses.
Head connection H

The steel structure is bolted on directly at the top of the wheel block.
Welded connection W

The wheel block end is welded directly to the supporting structure without intermediate flange.
Inserted connection I

The wheel block is pushed in between two cheeks and fastened with bolts. Lateral fine adjustment and fastening by threaded pin and nut.
