Summary

Dotec Roll Handling Systems

High-performance pneumatic roll lifters for safe, ergonomic, and efficient material handling

Dotec Roll Handling Systems are innovative, ergonomic lifting solutions specifically designed for safely lifting, turning, tilting and/or rotating rolls of paper, film, foil, textiles, and other flexible materials. Engineered with the operator in mind, these pneumatic-powered roll lifters are ideal for industries where speed, precision, and worker safety are paramount.

Dotec systems utilize a unique combination of compressed air technology and intuitive controls to allow a single operator to manage heavy roll loads with minimal physical effort. By integrating Dotec roll handlers into your production line, you can drastically, minimize the risk of injuries, optimize the flow of your operation, and reduce downtime through remote support.

Full customizable roll handling systems
Operates with 100% digital pneumatics
Ergonomic design thanks to the Dotec Ergohandle for precise controls
Automatic adjustments to ensure secure, consistent center of gravity balancing
Load capacities up to 110 lbs (500 kg) - depending on the specific configuration

Custom roll lifting equipment built for safety and control

Dotec's Friendly LiftAssist system is designed for ease of operation, speed, and ergonomics, all thanks to its unique design features.

The user-friendly design is all thanks to the central features of the LiftAssist:

Dotec Ergohandle – Operators will have a learning curve of just minutes. The Ergohandle has intuitive controls that respond to simple finger-tough movements while still having precise control.
Air-balancer – The strain of lifting rolls is minimized as the compressed air system creates a floating effect as operators handle heavy loads. Minimal operator effort is required. Pneumatics also allow for proportional controls for smooth handling and precision.
Remote support – Updates, adjustments, troubleshooting, and even remote support can be done over an internet connection.

Benefits:

Boost operator efficiency
Reduce workplace injuries and comply with OSHA standards
Preserve product integrity
Flexible integration into existing workflows
Low maintenance and high reliability

Product Features

Dotec Ergohandle

The central feature of the LiftAssit is the Dotec Ergohandle. The Ergohandle allows for intuitive control of the lifters with no more effort than a fingertip touch to control both direction and speed. The ergonomic handle glides freely up and down through the operator’s hands – no bending or stretching needed when lifting to high or low positions.

The Ergohandle also features proportional speed – the handlers move slowly with a light press and faster the further you press. Up and down movement of the handler is controlled by one set of handles while tilting/rotating and roll release is done with a second set of handles set behind the first. This configuration keeps operators able to keep their hands easily on the handler, comparable to steering a car, and operate the full capacities of the handler. Simple, intuitive controls also means the learning curve for operators is short. The handler must always obtain enough counter pressure in order to release a roll so products cannot accidentally be released during the lifting process – safety first!

Air-Balancer

The air-balancer makes the elastic vertical movements of the LiftAssit possible. The winding and unwinding of the system’s balancer cable. This also creates an air cushion to support the load when it is stopped and keep it balanced.

Additional Options

Rotating Action – Rolls can be rotated through their center allowing wider and larger rolls to be lifted and rotated. An additional optional balance mode can be added allowing rolls to be taken directly from a shaft

Special Features:
- Core chuck options – for additional core sizes
- Anti-telescoping – clamps rolls from the outer diameter to stop rolls from telescoping
- Safety brakes – brakes on balancer, pivot of jib crane, or rail
- Balance mode – used when rolls are being directly offloaded from a spindle or shaft
- Slip off device – created easy removal of the chuck from the roll core

Infrastructure

To ensure smooth operation, The LiftAssist requires the correct infrastructure setup to allow for horizontal movement of the handler. Designed for a 24/7 production environment, the system’s high-speed performance along with ease of use and safety make the Dotec system a reliable choice for continuous operations. To make this all possible, the infrastructure is the backbone of the Dotec total system. Most common solutions are a rail system or jib crane – determined by area lay-out.

Rail systems and Gantries

Rail profiles provided a minimal rolling resistance of ≤1% of the load. With a strong but light profile made from aluminum, large spans and load capacities can be achieved. Gantry systems created seamless maneuvering across production layout and come equipped with Dotec’s top-quality, aluminum rails. Systems are custom based off required dimensions to suit your operation.

Jib crane

Where space or headroom is limited, a jib crane can be used. Perfect for short transfer process, jib cranes are designed for ergonomic, smooth movement while handling loads. Rotation can be locked to ensure safety and accommodate the needs of the process. The aluminum rail provides strength without sacrificing strength.
