The 2-arm universal precision mechanics puller with rotating pull hooks is used for pulling bearings, gears and discs in all common sizes for trades, workshops and industry. This makes it possible to detach any part that is on an axle and is freely accessible from the outside. The swiveling tow hooks ensure maximum freedom of movement even in restricted environmental conditions for adjustment to the respective clamping range and depth. There are different versions of the tractor within the series 41. The compact model 41-0 has a hexagon drive and a flat pressure piece on the spindle. The models 41-1 and 41-2 have a free-moving T-handle instead of the hexagon for working in very tight spaces. From size 41-3, the pullers are equipped with a hexagon drive and a dual spindle point. This allows the highest pulling forces to be achieved (3 to 7 t).
