Securing the rail
structure
IMPORTANT! In vertical applications, the rail structure must be secured by a load arres-
tor with a locking function to prevent it from falling.
The load arrestor must be designed for the total weight of the welding carriage and rail
structure. The manufacturer accepts no liability for any damage to persons or property
resulting from vertical use of the welding carriage without a load arrestor.
NOTE! Ensure that the cable on the load arrestor is kept permanently taut.
