摘要： A lift table includes a support table assembly mounted on a scissor arm mechanism. The support table assembly is raised and lowered automatically upon the imposition or removal of loads so that the height of the plane on which articles are being handled remains generally constant. Raising and lowering is effected via a lift spring assembly that acts without the assistance of any pneumatic or hydraulic actuators. The scissor arm mechanism of the lift table has angled arms and low-friction rollers to facilitate raising and lowering of the support table assembly and optimizing operation of the lift spring assembly. The resulting mechanically operated lift table is simple, reliable, and can be easily transported from location to location.

摘要： The present invention provides an improved raking or sweeping implement such as a yard and trail rake that is configured to be pulled by an all-terrain vehicle (ATV), lawn mower, or the like. Rake can include a frame portion connected to a rotary portion. Frame portion can include an attachment mechanism for attachment to a pulling mechanism, such as an ATV. Rotary portion can include a drive shaft, a plurality of rotary shafts with raking tines, and a planetary gear system for driving the rotary shafts as the rotary portion is rotated. Rotary portion can be rotated by engaging a tire of frame portion with a drive mechanism connected to drive shaft such that rotation of the tire caused by pulling the rake causes the rotary portion to rotate. As rotary portion rotates, planetary gear system causes raking tines to rotate forwardly, raking up debris.
