Roll tongs
In the “rolling” production process, materials are formed using rotating rollers. Both the working rollers and the back-up rollers that are used must be regularly ground. To ensure these rollers do not become damaged, they must be transported from the tool to the grinding machine in a particularly careful process. This is because some of them have a particularly sensitive surface. Roll tongs from WIMO® are an ideal solution for this challenge.
Like all products from WIMO Hebetechnik, all roll tongs are custom-designed for the specific application scenario at the relevant place of use. All circumstances on-site are recorded and utilised to optimal effect in order to optimise the entire material flow. WIMO® roll tongs contain high-quality technology and many years of experience. Depending on customer requirements, they can transport one or more rollers at the same time. The tongs take the rollers into the grinding machine and later remove them. The rollers are transported in a particularly safe way that protects materials – in part because of the integrated cut-off strips and load-securing devices. The low-maintenance design minimises operating costs. WIMO® also offers a very good testing and repair service plus a secure spare parts supply for roll tongs, available for decades if required.
Work roller tong with horizontal rotation device
- Fast and precise alignment thanks to integrated positioning device
- Replaceable plastic protective pads on the contact surfaces protect the pins
- Horizontal rotation device for flexible roller positioning
- Slim gripping units enable direct loading and unloading of grinding machines
Hydraulically adjustable work roll clamp with RFID recognition
- Attachment device for quick alignment with plastic rollers
- Transport of rollers with or without installation pieces thanks to hydraulic height adjustment
- Hold-down devices prevent installation pieces from twisting during individual transport
- Hydraulic counterweight for horizontal load absorption
- RFID recognition for automatic type identification
Work roll tong with four height-adjustable support columns
- Precise centering and guidance during storage and retrieval
- Four leading support columns for particularly gentle roll transport
- Optimized for sensitive roll surfaces
- Robust design for continuous use in rolling operations

Lifting beams with motorized bob weight
- Design suitable for lateral installation and removal of work and backup rolls from the cold rolling mill
- The counterweight can be individually adjusted electromechanically to the respective roll type
- Gentle roll transport thanks to load absorption at the roll journal
Work-roll tong for gripping roll surface
- Safe thanks to tong arm drive via self-locking trapezoidal thread spindle.
- Universally applicable thanks to load acceptance on the rolled roller. This solution allows different work rollers to be accepted regardless of the geometry of the mounting pieces.
- Flexible thanks to hydraulically height-adjustable attachments, one or two work rollers can be transported simultaneously with or without mounting pieces.
- The special geometry of the tong arms also enables grinding machines to be loaded and unloaded.

Back-up roll tong for gripping roll surface
- Safe thanks to tong arm drive via self-locking trapezoidal thread spindle
- Universally applicable thanks to load support on the rolling roller. This solution allows various work rollers to be supported regardless of the geometry of the mounting pieces.
- Flexible thanks to hydraulically driven rotating device for installation pieces. The worker manually couples or decouples the turning units with the installation pieces.
- The special geometry of the gripper arms also enables grinding machines to be loaded and unloaded.
Spreader for transporting supporting rolls
- Convenient load handling thanks to automatically folding and unfolding lifting claws
- No external power supply required
- Durable thanks to extremely robust steel construction
Back-up roll tong with motorized adjustable tong arms
- Secure thanks to tong arm drive via self-locking trapezoidal thread spindle
- Gentle load acceptance thanks to advance contact devices that center the tong on the mounting pieces
- The load is picked up positively by a total of 4 pick-up pins which engage in the pick-up holes of the mounting pieces
- Durable thanks to extremely solid metallurgical design
Back-up roll tong with motorized tong arms adjustable in horizontal direction
- Secure thanks to tong arm drive via self-locking trapezoidal thread spindle
- The electromechanical longitudinal and transverse adjustment allows the back-up roll tong to be individually adapted to different roller dimensions
- The load is held in a form-fitting manner by a total of 4 mounting pins which engage in the mounting holes of the mounting pieces
- Flexible roller positioning thanks to integrated rotating device
- Durable thanks to extremely solid metallurgical design
Work-roll tong
- Safe thanks to tong arm drive via self-locking trapezoidal thread spindle.
- Universally applicable thanks to load acceptance on the rolled roller. This solution allows different work rollers to be accepted regardless of the geometry of the mounting pieces.
- Flexible thanks to hydraulically height-adjustable attachments, one or two work rollers can be transported simultaneously with or without mounting pieces.
- The special geometry of the tong arms also enables grinding machines to be loaded and unloaded.
WIMO work-roll tongs are specially designed for the precise and gentle transport of work and backup rolls in forming technology. They enable safe handling of sensitive roll surfaces – from removal to the grinding process to reinsertion into the machine. Each tong is individually adapted to the local conditions and technical requirements.
