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 has a ramp portion configured for reciprocating movement between a stowed position, a deployed position, and a neutral position, and a counterbalance. The counterbalance includes a compression spring and an engagement fitting associated with a first end of the spring. A first bearing element is operably coupled to the ramp portion so that movement of the ramp portion from the neutral position toward the stowed position engages the first bearing element with the engagement fitting to move the first end of the spring toward a second end of the spring. A second bearing element is operably coupled to the ramp portions of that movement of the ramp portion from the neutral position toward the deployed position engages the second bearing element with the engagement fitting to move the first end of the spring toward the second end of the spring.

摘要： A ramp assembly has a ramp portion configured for reciprocating motion between a stowed position, a deployed position, and a neutral position. A counterbalance is associated with the ramp portion and includes a drive element with a spring fitting. The drive element is rotatably coupled about a first axis of rotation that moves along an arcuate path. A restraint is slidably coupled to the drive element and is also rotatably coupled about a fixed axis of rotation. An end stop is associated with the restraint. A compression spring is disposed between the spring fitting and a portion of the restraint so that the compression spring provides a force to bias the ramp portion toward the neutral position.

摘要： An operable ramp is moveable between a raised position, in which the ramp forms a pair of steps, and a lowered position, in which the operable ramp provides an inclined surface. The operable ramp includes a first panel rotatably coupled about a first axis that moves back and forth when the operable ramp moves between the lowered position and the raised position. A link is rotatably coupled to the first panel about a second axis and is itself rotatable about a fixed third axis. A second panel is rotatably coupled to the link between the second axis and the third axis, and a third panel is rotatably coupled to the second panel about a fourth axis. When the ramp moves between the raised and lowered positions, the fourth axis rotates about a fixed fifth axis. A linkage selectively rotates the first panel about the first axis.

摘要： A step assembly includes a tread and an actuator. The actuator is operably coupled to the tread and configured to selectively reciprocate the tread between a raised position and a lowered position. The actuator is rotatably coupled to the actuator mount, which is slidably coupled to a frame. A spring selectively maintains a position of the actuator mount relative to the frame.
