Don,
Concisely put. May I, with your permission, copy and paste and print this for my own use as a guide to setting up my gin poles? I'll put your name at bottom as author if you wish.
I've never used a gin, have so far hung a block to an adjacent building (sometimes w a mast/pole fixed to it) or a nearby tree. Also attached a block to the forks on a all-terrain telescoping forklift. We always set up guy ropes and holdback ropes.
I've raised more blown over trees than I have buildings with ropes and snatch blocks, comalongs etc. Always w the fallen tree re-raising I climbed nearby tree(s) to hang a snatch block and sometimes tie guy ropes to the "gin tree". I've raised fallen live trees 20' - 90' tall. Most are in wet ground or on ledge so the roots can't hold in the wind or heavy snow. Gotta make safety/strength judgement on the "gin tree", figure what angle I can get and where the lift point on the fallen tree will help most with the overall balance of of the load. Buckingham Co makes top quality snatch blocks and rope handling tools for arborists.
I've gotten some other good rigging rules and diagrams from the Crosby Company catalog and booklets. Grainger used to sell Crosby (made in USA, tested, rated and guaranteed) shackles, turnbuckles, eyebolts, threaded eyes, snatch blocks, wire rope clips etc, but they switched to unbranded mostly chinese imitations of noticeably lower quality. I returned the offshore junk to Grainger and found a distributor for Crosby products in Oklahoma. Crosby also has good training and safety literature.
www.thecrosbygroup.comRooster, I like your simple design and clear picture of the rope bullhook. Do you have rights to its design? Is it OK for me to have some made for my own use?
