Abstract
A cylinder prop assembly is cooperable with a lift cylinder for a scissor lift and includes a cylinder prop displaceable between a disengaged position, in which the cylinder rod is movable relative to the cylinder housing, and an engaged position in which the cylinder rod is locked from displacement relative to the cylinder housing. An actuation lever is coupled with the cylinder prop and is accessible to displace the cylinder prop between the disengaged position and the engaged position.
Claims15
A scissor lift comprising:
- a lift cylinder including a housing and a cylinder rod, wherein the cylinder rod is displaceable relative to the housing by hydraulic fluid;
- a scissor arm assembly displaceable between a raised position and a lowered position by the lift cylinder;
- a platform supported by the scissor arm assembly;
- and
- a cylinder prop assembly acting between the scissor arm assembly and the lift cylinder and including:
- a retaining plate secured to a distal end of the cylinder rod and pivotable relative to the cylinder rod,
- an actuation lever coupled with the retaining plate, and
- a cylinder prop coupled with the retaining plate, wherein the cylinder prop is operatively connected with the actuation lever via the retaining plate such that the cylinder prop is displaceable via the actuation lever between a disengaged position in which the cylinder rod is unlocked for displacement relative to the housing and an engaged position in which the cylinder rod is locked from displacement relative to the housing.
A cylinder prop assembly acting between a cylinder rod and a cylinder housing, the cylinder prop assembly comprising:
- a retaining plate securable to a distal end of the cylinder rod and pivotable relative to the cylinder rod;
- an actuation lever coupled with the retaining plate;
- and
- a cylinder prop coupled with the retaining plate, wherein the cylinder prop is operatively connected with the actuation lever via the retaining plate such that the cylinder prop is displaceable via the actuation lever between a disengaged position in which the cylinder rod is unlocked for displacement relative to the housing and an engaged position in which the cylinder rod is locked from displacement relative to the housing.
A cylinder prop assembly cooperable with a lift cylinder for a scissor lift, wherein the lift cylinder includes a cylinder rod and a cylinder housing, the cylinder prop assembly comprising:
- a cylinder prop displaceable between a disengaged position in which the cylinder rod is movable relative to the cylinder housing and an engaged position in which the cylinder rod is locked from displacement relative to the cylinder housing;
- and
- an actuation lever operatively coupled with the cylinder prop and accessible to displace the cylinder prop between the disengaged position and the engaged position.
