Assembly and Disassembly Instructions

Cautions

1. Read and understand instructions before using this gantry.
2. Inspect gantry thoroughly before using. See the Aluminum/Steel Thrifty Frame Assembly Instructions (Forms 386 and 387) Parts List for damaged or missing parts.
3. Do not lift more than rated capacity.
4. Center hoist over the load.
5. Do not allow the load to swing or roll against any supporting members.
6. When moving the gantry under load, push on the gantry, not the load. Be certain that the rolling surface is hard, level, clean, and smooth.
7. Do not move the gantry over 50 feet per minute (1/2 m.p.h.).
8. Not to be used for lifting or supporting humans.

Before You Begin

1. Place parts on a flat surface, preferably on cardboard to keep small parts clean and organized.
2. Select a clear area to assemble the crane. The work envelope should be at least as large as 2 times the leg length and wider than the beam. This clear area should be serviced by a crane or lifting device capable of lifting the entire weight of the completed crane. The lifting device must have sufficient height for the posts to be raised clear of the frames.
3. Select tools for fastening the nuts and bolts.
4. You will also need C-clamps to hold the trolley in place while the crane is assembled.
