Ramp DB6050F / DB6050MZ

Crawford Drawbridges are manually placed dock plates which can be used as an alternative to a Dock Leveller. ASSA ABLOY Entrance Systems offer two variation of the Crawford Drawbridge system - Crawford DB6050F (Fixed Position) and DB6050MZ (Guidance Rail). Where dock levellers cannot be accommodated, these traditional solutions can be utilised at open ramps to service vehicles of similar size, or a fleet of trailers with roughly the same design. The Crawford Drawbridge Leveller DB6050F (Fixed) is installed into the floor at a fixed position, whereas the Crawford DB6050MZ is cast into a guidance rail, which runs across the front edge of a ramp or bay opening. The latter alternative makes it possible for the leveller to moved horizontally in order for it to be operated in different positions along a ramp/bay. When not in use, a Crawford Drawbridge can be secured in the vertical position by a safety lock. Both Fixed and Guidance Rail versions are made of steel and are equipped with a heavy-duty spring device. Spring assistance enables heavy Drawbridges to be conveniently lifted and lowered by hand.
