§ 171.96. Power lift.
(a) General. A school bus or school vehicle that is used specifically for the transportation of school children who utilize wheelchairs or other types of mobility devices, or who require life support equipment which cannot use the regular service entrance shall be equipped with a power lift. A power lift system shall comply and be installed in accordance with any applicable FMVSS. If a power lift system is inadequate to load or unload school children having special or unique needs, a ramp device may be installed.
(b) Specific requirements. The requirements for power lifts are as follows:
(1) The power lift shall be located either in the rear or on the right side of the vehicle body, but confined within the perimeter of the vehicle body when not extended. The power lift may not be attached to the exterior sides of the vehicle.
(2) The lifting mechanism shall be able to lift a minimum pay load of 800 pounds. A clear opening and platform to accommodate a 30-inch wide wheelchair shall be provided.
(3) When the platform is in the fully up position, it shall be locked in position mechanically by means other than a support or lug in the door.
(4) Controls shall be provided that enable the operator to activate the lift mechanism from either inside or outside of the school bus. There shall be a means of preventing the lift platform from falling while in operation due to a power failure.
(5) Power lifts shall be equipped so they may be manually operated in the event of a power failure.
(6) The lift travel shall allow the lift platform to rest securely on the ground.
(7) Edges of the platform shall be designed to prevent the wheelchair or other type of mobility device from slipping or rolling off the platform and to prevent the operator’s feet from being entangled during the raising and lowering process.
(8) A self-adjusting, skid resistant plate shall be installed on the outer edge of the platform to minimize the incline from the lift platform to the ground level.
(9) A circuit breaker, fuse or an electronic device which provides protection against short circuits, thermal overloads and reversed polarity shall be installed between the power source and the lift motor, if electrical power is used.
(10) The lift mechanism shall be designed to prevent excessive pressure from building in the hydraulic system when the platform reaches the full up or full down position.
