摘要： A counterbalance for a ramp assembly includes a chain assembly and a spring assembly. The spring assembly includes a spring and first and second spring fittings. The first spring fitting restrains a first end of the spring when the ramp portion is between a neutral position and the stowed position and moves the first end of the spring toward a second end of the spring when the ramp portion moves from the neutral position toward the deployed position. The second spring fitting is spaced from the first spring fitting and restrains the second end of the spring when the ramp portion is between the neutral position and the deployed position. The second spring fitting moves the second end of the spring toward the first end of the spring when the ramp portion moves from the neutral position toward the stowed position.

摘要： A vertical lift platform assembly 100 has a lift platform 140, which is translatable in a vertical direction between at least a raised position and a lowered position by at least one actuator 200. The lift platform 140 may be surrounded on all sides by vertically extending walls 112 and one or more doors 110 to provide access to the lift platform 140. A control panel 113 enables an operator to control the vertical travel of the lift platform 140.

摘要： A ramp assembly includes a ramp disposed within a vehicle. The ramp assembly further includes a movable floor hingedly coupled at a first end to the ramp. A reciprocating mechanism reciprocates a second end of the movable floor between a lowered position when the ramp is in the stowed position, and a raised position when the ramp is in the deployed position.

摘要： A drive assembly (100) for a wheelchair lift is provided. The drive assembly (100) includes an actuating assembly (104) in communication with a component of the wheelchair lift. The actuating assembly (104) is configured to selectively apply a driving force to move the component between at least first and second positions. The drive assembly (100) also includes an overload assembly (102) coupled to the actuating assembly (104). The overload assembly (102) is configured to redirect application of the driving force from the component to the overload assembly (102) when a force applied to the component exceeds a predetermined limit.

摘要： A ramp assembly (20) having a frame attachable to a vehicle having a floor is disclosed. The ramp assembly further includes a platform coupled to a portion of the frame, a ramp having a weight, and a reciprocating mechanism disposed between the ramp and the platform coupled to a portion of the frame. The ramp assembly also includes a reciprocating mechanism disposed between the ramp and the platform for reciprocating the ramp between a deployed position and a stowed position in response to a load. The reciprocating mechanism counterbalancing the weight of the ramp during actuation of the ramp between the deployed and stowed positions to reduce the load required to reciprocate the ramp between the deployed and stowed positions.
