Wollard International Mobile Stairs can reach doorsills up to 228". The company offers the CMPS 170 Stair and CMPS 228, which offer a reach of 170.5" and 228", respectively. Both models are available with electric power. A quiet, efficient propulsion system offers a pro-active option. Diesel and gas power units also are available. Highly maneuverable models are easy to position, as the operator can see doorsills during approach to the airplane to make final docking and alignment simple. The rugged wraparound steel bumpers protect units from dings and dents inherent with ramp traffic, and the company says they hold up longer in the ramp environment compared to modified pick-ups. The units are designed to ARP 836 and share design elements and parts commonality with several other Wollard products to simplify fleet maintenance and reduce parts inventory.
