Abstract
An elevating platform assembly is provided. In accordance with one exemplary embodiment a platform is present and is moveable along a travel distance of a mast. A cylinder is provided and is capable of being actuated. The cylinder is used to move the platform along the travel distance.
Claims20
An elevating platform assembly, comprising:
- a mast;
- a platform carried by said mast and moveable along a travel distance of said mast;
- and
- a cylinder capable of being actuated, wherein said cylinder is used to move said platform along the travel distance.
1 more element
An elevating platform assembly, comprising:
- a mast;
- a platform carried by said mast and movable along a travel distance of said mast;
- a hydraulic cylinder capable of being actuated;
- a cable configured for transmitting motion of said hydraulic cylinder to said platform for use in moving said platform along the travel distance;
- and
- a hydraulic brake configured for locking said platform to said mast such that said mast is fixed at a particular position along the travel distance.
3 more elements
An elevating platform assembly, comprising:
- a mast, wherein said mast has a braking plate;
- a platform carried by said mast and movable along a travel distance of said mast, wherein said braking plate is arranged so as to extend substantially along the travel distance;
- a hydraulic cylinder capable of being actuated;
- a pulley system in communication with said hydraulic cylinder;
- a cable attached to said pulley system, wherein said cable is configured for transmitting motion of said hydraulic cylinder to said platform for use in moving said platform along the travel distance, wherein said pulley system is arranged so that an amount of movement of said hydraulic cylinder is translated into a greater amount of movement of said platform along the travel distance;
- and
- a hydraulic brake carried by said platform and configured for engaging said braking plate in order to lock said platform to said mast, wherein said hydraulic brake is normally locked so that said platform is locked to said mast, wherein said hydraulic brake is capable of being hydraulically actuated so as to be urged into an unlocked configuration to allow said platform to move along the travel distance.
