Optimal Manual Control During Rotation of Rolls and Emptying of Drums and Barrels

The Manual Linear Clamp with Manual Rotation Unit (MLC-MRU) enables secure handling of cylindrical and similar loads such as drums, barrels, and rolls through controlled lifting, gripping, and manual sideways turning.

By pairing a linear clamping mechanism with a hand-operated rotational module, the system allows the operator to guide the load with direct, tactile control throughout the entire manipulation process. This makes it particularly suitable for tasks requiring careful adjustment and smooth, incremental rotation.

System Configuration - Two Integrated Units

The MLC-MRU consists of two components operating in tandem:

• Manual Linear Clamp (MLC)
  
• Manual Rotation Unit (MRU)

Manual Linear Clamp (MLC)

The Manual Linear Clamp (MLC) is designed for manual clamping of loads using various lifting arms and grippers depending on the load type.

The MLC can be combined with tipping or rotation units depending on the application and handling requirements. It is commonly used for handling drums, barrels, rolls, and similar loads.

The MLC consists of a self-locking worm gear system that drives the carriages via manual operation of the handwheel. The mechanical design enables controlled clamping and maintains grip during lifting and handling operations.

Key characteristics:

• Manual self-locking worm gear system with handwheel-operated carriages 
  
• Controlled and stable clamping during lifting and handling operations 
  
• Maximum clamping force of approximately 7500 N 
  
• Compatible with various manipulation tools, including rotation units such as Electric Rotation Unit (ERU) and Manual Rotation Unit (MRU) and tipping units such as Electric Tipping Unit (ETU) and Manual Tipping Unit (MTU)
  
• Supports point grip, plate grip, and belt grip configurations
  
• Suitable for rolls, drums, barrels and similar loads
  

Manual Rotation Unit (MRU)

The Manual Rotation Unit (MRU) is designed for controlled rotation of loads lifted via an attached lifting tool mounted directly to the unit. Rotation is achieved manually by the operator through a side-mounted handle, which drives the system mechanically.

Internally, a self-locking worm gear transfers the applied manual force to the main axle, ensuring smooth and controlled rotation while maintaining the load securely in position when movement stops.

The outer main axle is fitted with a flange interface for mounting the lifting tool. This configuration allows flexible integration with different lifting setups while maintaining stable and reliable load handling throughout operation.

Key characteristics:

• Self-locking worm gear system for secure load holding 
  
• Manual handle-operated rotation for direct operator control 
  
• Large gear ratio for manipulation of heavy off-centre loads.
  
• Flange interface for flexible attachment of lifting tools 
  
• Compatible with various lifting tool configurations such as clamps (Electric Clamp (EC), Manual Clamp (MC), Manual Clamp with Spindle (MCS), Electric Linear Clamp (ELC), Manual Linear Clamp (MLC), forks (Fork (F), Adjustable Fork (AF) and expanders (Electric Expander Unit (EEU) and Manual Expander Unit (MEU)
  

Construction and Application

Rugged industrial design with all-stainless-steel construction ensures durability in demanding environments.

A hygienic design variant is available for cleanroom applications and for use in the food and beverage industry.
