Flagstone installing device, has base plate abutting to articulated arms to maintain claws isolated while moving device downwards, and providing support point to disengage, by tilting lift bar, one claw when flagstone is installed on ground

摘要

The device has a lift bar (7) whose lower end has a base plate (9) that abuts to two articulated arms (4, 5) to maintain two claws (1, 2) isolated while moving the device downwards. The base plate provides a support point on an upper side (3a) of a flagstone (3) to disengage, by the tilting of the lift bar, one of the claws of the flagstone when the flagstone is installed on the ground.
