Customized and configurable long-stroke gripper ELG

With a gripping force of up to 12,000 N

Individual. Powerful. Flexible.

Customized and configurable long-stroke gripper ELG.

The SCHUNK ELG is the latest highlight among the configurable grippers used for handling large, heavy parts in the packaging, automotive, white goods and logistics industries, among others, and is actuated by an electric drive with a freely adaptable servomotor.

This electrical 2-finger parallel gripper with long jaw stroke, high gripping force and profiled rail guide for the use of long gripper fingers.

 The gripper can be finely adjusted and continuously positioned over the entire stroke from 100 to 400 mm.

It has a unique force-stroke ratio and offers an instantly available and controllable gripping force of up to 3,000 N in size 30 to 12,000 N in size 120.

Advantages

• High degree of flexibility due to the large jaw stroke and high gripping force
  
  
• Adaptable drive motor for flexible actuation and easy integration into existing control concepts
  
  
• Position- and torque-controlled movement of the gripper for the highly flexible gripping of a wide range of geometries and types of parts
  
  
• Food-grade lubrication - 
  The product contains food-compliant lubricants as standard. The requirements of standard EN 1672-2:2020 are not fully met. The corresponding. 
  NSF certificates can be accessed at https://info.nsf.org/USDA/Listings.asp can be called up with the help of the lubricant information in the operating manual. 
  Components such as rolling bearings, linear guides, or shock absorbers are not provided with food-compliant lubricants.
  
  

Field of Application

Individual solution for a wide range of applications through the customized configuration of the gripper in clean to slightly
dirty environments.

Sectional Diagram

A servomotor drives the ball screw via a toothed belt, which linearly moves the base jaws connected to the spindle nuts and profiled rails.

1.  Drive - 
Servomotors from numerous manufacturers can be adapted

2.  Kinematics - 
High bearing load capacity and accuracy due to proven combination of ball screw and toothed belt

3.  Profiled Rail Guide - 
Highly loadable, nearly backlash-free base jaw guidance for long finger lenghts

4.  Base Jaw - 
For the connection of workpiece-specific gripper fingers.

Individually configurable stroke

1.  Variant with 100 mm stroke per jaw

2.  Variant with 400 mm stroke per jaw

The stroke per jaw can be configured to customer specifications between 100 mm and 400 mm per jaw with millimeter precision.

(For size 10, the stroke is limited to 300 mm.)
