A gin pole provides support while building a tower. There are two ways of building a tower. One method requires laying the tower components on the ground as it is assembled, then lifting the entire structure into place. This works fine for small towers, but larger towers can bend or crack under the stress. A gin pole remedies this situation. Attached to the side of the tower, this pole, which has a pulley at the top, allows workers to haul each component to the top of the tower. After the component is installed, the gin pole is moved up to the new component, ready to build the tower even taller.
- Skill level:
Things you need
- 8-foot, 2-inch diameter steel pole
- Carbide drill bit
- Two 4-inch eye bolts, with nuts
- 90.7kg. steel pulley
- Steel quick link
- Two 2-inch U bolts
- 200 yards of nylon rope or steel cable
Drill a hole through the steel pole two inches from one end. Insert one eye bolt and screw the nut on tight.
Attach the steel pulley to the hole in the eye bolt with the quick link. Thread the rope through the pulley.
Drill a second hole 18 inches from the other end of the steel pole. Insert the eye bolt and tighten the nut.
Attach the bottom of the pole to the highest portion of the tower with both U bolts below the eye bolt. The eye bolt prevents the pole from slipping through the U bolts.
Pull the next section of the tower into place and bolt the sections together. Remove the U bolts and move the gin pole up the tower.
