Abstract:
A knee range-of-motion exercise device includes a rail assembly, foot sled, and single continuous stretch-control rope. The rail assembly has opposing first and second ends, and at least one longitudinal rail extending between the ends. The foot sled is carried on the longitudinal rail, and is adapted for longitudinal sliding movement between the first and second ends of the rail assembly. The stretch-control rope has a first free end attached to the foot sled, a second free end attached to the first end of the rail assembly, a first looped end passed around a first pass-around rope guide fixed to the second end of the rail assembly, a second looped end passed around a second pass-around rope guide fixed to the foot sled, and a third looped end extending freely outwardly from the first end of the rail assembly for access by a user.
Abstract:
The present invention relates to a method and apparatus for the handling of rods such as drilling rods, roof bolts, or rib bolts, so that they can be removed directly from a storage cradle near a drilling rig or other mining operation machinery. The invention removes the need to manually load rods into drill rigs or other machinery, by a system of transportation mechanisms made up of straps and/or hydraulic actuators, and gate mechanisms to control the entry and exit of the rods from a storage cradle. Gripping mechanisms are also included to deposit the rods to and from a desired location on the drill rigs or other machinery.
