Rack and chain lifting device

The invention is a rack and chain lifting device. The purpose is to convert rotational motion to linear motion in a way that is superior to a rack and pinion device because, first, it allows for more points of contact with the rack through the use of a silent chain in place of a pinion, and, second, because it can be used in corners since the motor can be distanced from the rack by means of the silent chain. The invention comprises a silent chain with link plates that are shaped such that the teeth of the link plates are offset when the chain is straightened, allowing the profile of the silent chain to correspond with the profiles of both gears and racks. The invention also comprises a rack that can be placed in corners. Some embodiments include a system of gears, a motor, and a mounting platform.

Lifter
10611612 · 2020-04-07 ·

A lifter includes a support base, a first elevating stand assembly, a first elevating-drive mechanism, a turning-drive mechanism and a bracket mechanism. A lower portion of the first elevating stand assembly is provided with two sets of first fixing racks. The support base is symmetrically mounted on the first fixing racks. One side of the first elevating stand assembly is provided with a first elevating-drive mechanism. A first elevating stand is installed inside the first elevating stand assembly. The first elevating-drive mechanism drives the first elevating stand to move through the transmission mechanism. The turning-drive mechanism is provided with a support base. One end of the support base is hinged to a movable support frame. The other end of the support base is provided with a locking assembly. The turning-drive mechanism is provided with a bracket mechanism.

METHOD AND APPARATUS FOR TRANSPORTING AND STEERING A HEAVY LOAD
20240025499 · 2024-01-25 ·

A method and apparatus for transporting heavy machinery, equipment or other heavy loads from one location to another, whereby the apparatus may be constructed as a walking machine including a plurality of lifting assemblies operative to lift the load above the supporting surface and then move the load relative to the supporting surface by transporting the load via rollers or tracks in the walking machines. In one example, the lifting assemblies are provided with separate longitudinal and lateral drive mechanisms independently operative for translating the load in either or both longitudinal and lateral directions.

SELF LOADING CONTAINER
20190329973 · 2019-10-31 ·

A self loading container with specific improvements upon prior art. The aim is to expand self loading from industrial multi mode shipping units to less costly end uses with a range container sizes, shapes and customizations that perform common tasks and that can be self loaded into any size vehicle. Gravitational stability is improved by relocating the main rolling means of container from the bottom of vertically extendable jacks or legs to horizontally extendable support rails directly under container. As such, extendable legs are used only to vertically level container with a receiving surface onto which it can then be horizontally transferred by means of its horizontally extendable support rails. Cost and operating improvements include a simplified coupling mechanism torqued for heavy loads with which front and rear leg extension and retraction can be either in pairs, combined or locked. Operating simplicity, visibility and safety are improved by locating all manipulative tools on the same side of container and within easy reach. Ease of self loading container into vehicles and its safe retention during transport is made possible by retainer rails on an insertable vehicle cargo floor that automatically pivot to encase the container support rails.
