The Crawford drawbridge is the best solution for open ramps and for servicing vehicles of roughly the same size.
Crawford drawbridge levellers DB6050F fix version & DB6050MZ movable version Z-profile
The Crawford drawbridge leveller DB6050F is installed in a fix position, and the Crawford DB6050MZ is installed in a guidance rails placed in the front edge of the ramp.
The latter alternative makes it possible for the leveller to operate in different ramp positions. When not in use, the drawbridge is secured in the vertical position with a safety lock. Both versions are steel constructions equipped with a heavy-duty spring device, enabling it to be conveniently lifted and lowered by hand. Hot dip galvanising is standard to ensure corrosion resistance. The lip is a segmented aluminium alloy lip, compensating for sloping vehicle beds and facilitating smooth passages.
