The Invicta Mechanical Scissor Grab LEGO Block (Model ISG-6-LEGO) is specifically designed to lift, move and release LEGO-style interlocking blocks safely on a building site or yard — an alternative to the standard ISG-6 introduced to handle all styles of interlocking block, whether with rounded or angular lugs. The actuator plate sits on the raised profile of the block top to trigger the grab mechanism, and can be replaced with standard wheels for future use with conventional block packs. Manufactured in Leeds by Invicta Forks & Attachments.
Key Features
- LEGO block compatible — actuator plate operates on the raised profile of interlocking blocks
- Convertible design — actuator plate replaceable with standard wheels for conventional blocks
- Fully automatic mechanism — operates mechanically — no hydraulics required
- Segmented interchangeable rubber pads — easy to replace when worn
