Installation of the wire
When setting up an Emergency stop grab wire system from ABB Jokab Safety it is recommended to do the
tensioning of the wire by using of ABB Jokab Safety Tensioner / Gripper accessory. The installation of the
tensioner accessory reduces the installation time. The eyehook, tensioner thimble and the wire strength
gripper are in one assembly which enables rapid connection to the switch eyebolts and fast and accurate
tensioning of the wire. Thanks to the switch viewing window, systems can be accurately and quickly
tensioned. The double clamp mechanism prevents wire slippage.
The end of the safety wire is fed through a central hole in a cone shaped guide which protrudes from the
main housing. After being fed through the guide hole, the wire enters the main housing by going through a
feed hole and then is looped back through 180 degrees and is fed through a second feed hole on the
opposite side of the mechanism. The wire is then pulled for maximum tension and is locked in position by a
locking bar inside the main housing which is moved by turning an Allen type locking bolt.
Because of the added friction on the eyebolts and wire when navigating corners, a corner pulley can be used
to navigate inside or outside corners without causing damage to the wire.
1. Tension to mid position as indicated by the green arrows in the viewing window of each switch
2. The tensioner thimble allows immediate accurate and final tensioning of the wire, whilst viewing the
tension marker through the viewing window on the switch
3. For systems up to 50 meter Quick Link termination is provided for easy connection to either a Safety
spring or Switch eyebolt. (Note for systems above 50 meter a Tensioner / Gripper is required each
side).
