A movable lifting device has a lifting and fixing device (10) and a moving device (20). One end of the lifting and fixing device is connected to the moving device, and the other end thereof is connected to a cargo to be shifted (30). The free rotation of the lifting and fixing device converts rotary motion into linear motion for lifting the cargo to-be-shifted. The movable lifting device has a simple and flexible structure, is easy to operate, and combines the functions of shifting and lifting. It can be operated anytime and anywhere, and is suitable for a wide range of applications. The movable lifting device reduces labor intensity, saves manpower and material resources, is cheaper to build, and easy to operate.

The Rolling Lever Dumbbell Handcart Method is a method of using a handcart to lift a dumbbell, that is organized with a curved front structure that creates a varying effective fulcrum for lifting dumbbells. This method solves the repeated strain problem associated with having to lift a dumbbell up to a necessary height. The operation of the method works by having the operator lean the entire handcart forward so that the front curved portion rolls forward upon the flooring. The Dumbbell is then secured and the same rolling motion is performed in the reverse direction. Once the Handcart is lifted to its upright position it can then be rolled to another location where it can then be leaned forward again to place the Dumbbell in a new location.

An apparatus may include an enclosure that includes a plurality of mounting features that are configured to receive information handling systems. A base may be disposed below the enclosure, coupled to the enclosure, and may include a plurality of wheels. The base may be coupled to the enclosure via a height adjustment mechanism configured to lower and raise the enclosure relative to the base.

A cart is disclosed for carrying a gas bottle. The cart includes a wheeled frame and a bottle support platform. The support platform is configured to pivot between a loading position in which a gas bottle may be loaded and/or unloaded from the bottle support platform and a cradle position in which the gas bottle and the bottle support platform are elevated. A bottle rest may support the bottle when the bottle support platform is in the cradle position. A bottle support spine may also, or alternatively, support the bottle during transportation and act as a lever for pivoting the bottle support platform between the loading position and the cradle position.

A device for attaching to a ski of a snowmobile includes first and second spaced apart legs includes a ski engaging portion that is configured to engage a bottom surface of the ski. At least one wheel is attached to the first and second legs. A cross bar connects the first and second legs proximate first ends thereof. A lever arm extending from the cross bar and is angularly positionable relative to the first and second spaced apart legs. A retaining member is attached to a distal end of the lever arm and has a surface configured to engage a tip end or a ski handle of the ski.

A materials handling system (10) comprising a first (60) and second ladder (70) section connectable together to form a longer ladder, a tensioning system (100) attached to each section for tensioning the connected ladder sections, and a trolley (110) arranged to travel along the connected ladder sections, wherein the system includes a cable (158) and pulley for moving the trolley along the connected ladder sections.

A device or system for transporting an object to be transported, such as a heavy roof mountable HVAC unit, via inexpensive mechanical lift features that may be easily assembled onto system components that include mobile features, such as wheels. The device and system may include three or more wheeled attachment features that are selectively attachable to the object to the transported. Each wheeled attachment feature may include a selectively variable height mechanism, such as a jack; a securing mechanism for securing each wheeled attachment feature to the object to be transported, the securing mechanism including, for example, a mounting plate and a securing tab for holding the wheeled attachment feature to the object; and a wheel coupled, for example, via an upright inner sleeve, to the variable height mechanism.

A device for attaching to a ski of a snowmobile includes first and second spaced apart legs. Each leg has a ski engaging portion proximate a second end that is configured to engage a bottom surface of the ski proximate outer edges thereof. The device includes at least one wheel attached to the first and second legs between the first end and the second end and a cross bar that attaches the first and second legs proximate first ends thereof. The device includes a lever arm extending from the cross bar between the first and second legs wherein the lever arm is configured to be angularly positionable relative to the first and second spaced apart legs. A handle is attached to a distal end of the lever arm and has a surface configured to engage a tip end or a ski handle of the ski. The device includes a retaining member attached to the handle that is configured to engage the ski handle, wherein when the ski engaging portions engage a bottom surface of the ski and the retaining member engages the ski handle, the ski is elevated and the at least one wheel engages the ground surface such that the skis do not contact the ground surface as the snowmobile is moved.
