Extension options for remote handling

Note: these assemblies are barrels only, for clamping into the extension units – No handles are supplied with them. These barrels are available in 1/2” only. Please note we can make barrel lengths to your requirements but long lengths may become unwieldy and allow more flex in the apparatus.

Mk3 Extension Unit - 1/2"

Part N° - 44-30365

This unit is used to increase the reach of a tong assembly.

This extension unit will require a change station to allow release from, and connection to, either a standard handle assembly or an Alpha adaptor more information on this part can be found in the tong head section.

The illustration shows both the handle and barrel assembly locked into the extension unit (left hand side) and the extension barrel assembly clamped to the extension unit (right hand side). The illustration shows the locking mechanism and how the trigger / push rod action is translated through the unit.

Mk3 Right Angle Adaptor - 1/2"

Part N° - 44-30360

This unit allows a tong assembly to operate through 90°. It is designed to be used with the tong head in a vertical orientation and not horizontal.

As for the extension unit, this adaptor will require the same change station as the tong heads to enable detachment from a handle assembly.

The fitment into this adaptor is also the same as for the extension unit, the handle and barrel assembly being inserted via the locking device into one end and a fixed length barrel assembly being clamped at the output end.

Trigger / push rod actuation through the unit is via the use of rack and pinion style push-rod inserts as shown below; this provides smooth movement with minimal play in the system.
