Gearmotor Switch Box
Our gearmotors have tremendous torque power, are super smooth acting, and quiet. The 'Medium torque' model will crank tower up in about 11 minutes or less. The 'Low torque' , faster 40 rpm model will fold smaller towers over in only about 6.5 minutes.
The motorized system can fold over a very heavy duty 72 ft. tower (over 25 sq.ft. at 80 mph model) with over 330 lbs. of deadweight loaded 4 feet above the apex. See table for other capacities.

The Fold Over Kit maybe be operated with manually at heights up to 64 ft. (it becomes difficult with more than that) or with a Gearmotor Kit attachment.
The Gearmotor Kit is modular and may be attached at anytime; only takes 15 minutes to install.
How much time, effort and money will you save with a motorized Fold-Over-Kit? Here are some costs:

Our Fold Over Kits are a great solution to folding over some of our tallest towers (tested on over 120 ft. models). This allows the owner to gain access to an antenna/instrument array within minutes, and WITHOUT climbing!
Add Gearmotor Kit to the FOK above for the total:
No other Mounting Stubs are needed for the kit; the only additional accessory needed, besides the gearmotor option, is the Screw Actuator System!
The Stand is mounted on easy-to-install clevis weldments which are fastened to large threaded anchor bolts. This type of base may also be used for direct tower to base connections (see Base page). The Stand itself consists of super-strong, doubled up legs and extra strong lattice to handle the additional torque sometimes experienced below a Fold Over Kit. While more expensive than a tower sections per foot, they have greater torsional and shear resistance.
Stands are fabricated with heavy and reinforced materials, much heavier than normal legs and braces. For an exact description on our sizing of tower section legs, please see Table 3 and 4 of our tower section specs. Stand legs are much thicker, composite legs and contain about twice as much material as a regular tower section; they are specially designed for the overturning vectors of a Folding tower.
