Abstract
In one embodiment, there is a unique heavy lifting system capable of transporting vertically heavy loads from grade to any elevation required by the project.
Claims19
A modular lift system comprising:
- a lift deck system having a long directional axis, a short directional axis, and further having four corners, the lift deck system being configured to be moved vertically from a surface to a height above the surface;
- a pipe column assembly positioned at each corner of the lift deck system, each pipe column assembly having a top section, a bottom section, and a pipe slot, the pipe slot extending substantially from the top section to the bottom section;
- a base pedestal positioned under each bottom section in each pipe column assembly and being secured to the surface;
- a top actuator frame assembly secured to the top section in each pipe column assembly;
- a threaded screw rod positioned within each pipe column assembly;
- a travel nut bracket assembly having a travel nut and being positioned about each treaded screw rod in each pipe column assembly, the travel nut bracket assemblies configured to vertically travel along the treaded screw rod when actuated, each travel nut bracket assembly having a bracket sleeve with a portion extending through the pipe slot;
- a pair of lift beam assemblies extending along the long directional axis of the lift deck system and being secured along corresponding sides of the lift deck system, each lift beam assembly separately extending between a pair of opposed pipe column assemblies along the long directional axis, each lift beam assembly having a pair of ends separately secured to the portion of the bracket sleeve extending through the pipe slot, and
- an actuator system in communication with the four threaded screw rods configured to rotate the four threaded screw rods to cause the vertical movement of the travel nut bracket assemblies, that further cause the vertical movement of the pair of lift beam assemblies and therefore raise and lower the lift deck system therewith.

A modular lift system comprising:
- a lift deck system having a first directional axis, a second directional axis perpendicular to the first directional axis, and further having four corners, the lift deck system being configured to be moved vertically from a surface to a height above the surface;
- a pipe column assembly positioned at each corner of the lift deck system, each pipe column assembly having a top section, a bottom section, and a pipe slot, the pipe slot extending substantially from the top section to the bottom section;
- a base pedestal positioned under each bottom section in each pipe column assembly and being secured to the surface;
- a top actuator frame assembly secured to the top section in each pipe column assembly;
- a threaded screw rod positioned within each pipe column assembly;
- a travel nut bracket assembly having a travel nut and being positioned about each treaded screw rod in each pipe column assembly, the travel nut bracket assemblies configured to vertically travel along the treaded screw rod when actuated, each travel nut bracket assembly having a bracket sleeve with a portion extending through the pipe slot;
- a pair of lift beam assemblies extending along the first directional axis of the lift deck system and being secured along corresponding sides of the lift deck system, each lift beam assembly separately extending between a pair of opposed pipe column assemblies along the first directional axis, each lift beam assembly having a pair of ends separately secured to the portion of the bracket sleeve extending through the pipe slot, and
- an actuator system in communication with the four threaded screw rods configured to rotate the four threaded screw rods to cause the vertical movement of the travel nut bracket assemblies, that further cause the vertical movement of the pair of lift beam assemblies and therefore raise and lower the lift deck system therewith.
