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 the crane’s 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. Assemble a work crew of no less than three. One will operate the lifting crane and the others will perform the assembly. You may need more to lift the higher-capacity legs.
2. Place parts on a flat surface, preferably on cardboard to keep small parts clean and organized.
3. Clear an open area at least as large as 2 X the leg length and wider than the beam.
4. For assembly, select an area with a safe lifting means. For the easiest and safest assembly, use an area with two overhead hoists (for example an overhead crane) to raise the I beam when required.
5. Get 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.
