Introducing  Heights' Aluminum Fold-Over-Kits--

Avoid the risk of tower climbing.  Adjust or change Antennae or instruments quickly and efficiently!

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!    Features include:

Can be mounted on our Four Foot Stand or between certain  8 ft. sections in tower

 

Folding over a 72 ft. tower (model rated at over 34 sq. ft. at 80 mph wind speed.)

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.

 

This design is super sturdy and will not shift or creak in the wind!  The three large axle-bolts slide into place for easy lockdown when the FOK is clamped shut.

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.
Tower Height* Max. Pay Load Capacity (lbs./KGs)
80 ft. 275 / 125
88 ft. 250 / 114
96 ft. 170 / 102

*For our Heights tower models only.

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.

How much time, effort and money will you save with  a motorized Fold-Over-Kit?  Here are some costs:
FoldOver for size 172 sections and sometimes 225 sections: $935
Fold Over for 225 & 288 size sections: $1055

Heavy Duty 1.25" Dia. Acme Screw ACTUATOR, hand crank bar included $415
Add Gearmotor Kit to the FOK above for total:
Gearmotor Kit, our 'lower' torque, 40 rpm,1 with screw-coupler, mount & drumswitch w/pendant $987
Gearmotor Kit, medium torque, 22 rpm,1 with screw-coupler, mount & drumswitch w/pendant $987
Gearmotor Kit, hi torque,2 with 12 ft of cording pre-wired with drum-switch3, etc.  Heavy-duty gearmotor available only on factory recommendation.  $1235

1, 2  Gearmotors are 120 Volt AC.

FOUR FOOT STANDS PRICE EACH WEIGHTS (lbs./KGs)
35" width, for towers with legs up to 2.88" size* $686 112 / 51
26" thru 30" width, for towers with legs at 2.88" size $637 97 / 44
26" width, for towers with legs up to 225" $580 88 / 40
18" and 22" width, for towers with legs up to 225" $565 80 / 36

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.

PRICES are subject to change without notice.  We give Amateur Radio Club discounts!
