Project #1

Design a hand-operated hydraulic lift and tilt drum lifter that is comparable to the one shown below (source: http://www.mcmaster.com/ ). You are to choose materials and dimensions such that components of the lift will not fail due to normal operating conditions. The following are brief overview of the major design steps:

a. Create a sketch of your overall design that includes all relevant components.

b. Use principles of statics to find the maximum hydraulic cylinder force needed to lift the load. Alternatively, use Working Model to determine the hydraulic cylinder force over the range of motion.

c. Use the results of step (b) to find a hydraulic cylinder and accessories that matches your demands. Follow and document selection procedure. Be sure that the cylinder will no buckle under the load.

d. Design the remaining components of your lift including hinges.

e. Create a set of engineering drawings that can be used to manufacture the lift. It is preferred to use solid modeling at this step.

f. Create list of components as explained in the first handout of the semester (http://www.me.unlv.edu/~mbt/440/Project_Format.html ).

Hydraulic Lift and Tilt Drum Lifters • 800 lb. Capacity

     Hydraulic muscle makes it easy to raise and tilt 360° in either direction full 55-gallon drums up to 800-lbs. and half-filled drums up to 500 lbs. Use with steel drums only. Hinged saddle securely holds loaded drum in position as it is tilted, drained, and lowered.
     Trucks have a heavy-duty, welded steel tubing frame, and a screw-down floor lock to keep units stationary. A hand lever adjusts the hydraulic cylinder for precise positioning. Base legs have two 8" x 2" polyolefin wheels with roller bearings and two swivel casters with 4" x 1 5/16" self-lube polyolefin wheels. Color is blue. Shipped assembled.
     The 60" hand-operated lifter has a hand crank tilt control. A few turns of the hand crank will tilt, and empty the drum. Drum is returned to the upright position and lowered by turning the release handle. The 72" hand-operated and electric lifters have a pull chain and chain wheel to control tilting. Electric lifter has an electric-powered hydraulic lift with 1 hp, 115 VAC, 60 Hz single phase TEFC motor. Motor draws 12.8 amps at full load. Lifter also has a hand lever control and an 8' long power cord with a 3-prong plug.
     Also Available: Replacement parts. Please ask for 3407T888 and specify part required.
