MASTS OR LIGHT TOWERS*
This telescoping three-stage steel light mast from Larson Electronics is designed to
allow operators to quickly and safely deploy lighting, cameras, and other electrical
equipment in locations where this equipment must be elevated to heights up to 25
feet for effective coverage. The trailer hitch mount design and pair of 1,000lb
adjustable outriggers allow for operators to deploy lighting and equipment in
remote locations and anywhere a truck or vehicle with a trailer hitch can be
driven.
This light boom operates on 12V DC and can be extended to 25 feet for maximum
area coverage and collapsed to 12 feet for applications where a smaller footprint is
required. The tower is constructed of square steel tubing with a lower section 8
feet in length and constructed of 4" x 4" square tubing, middle section 8 feet in
length and constructed of 3" x 3" square tubing, and an upper section 10 feet in
length and constructed of 2" x 2" square tubing. Each section has 2 foot of
overlap. The mast is elevated using an included electric winch with 3/16 inch
cable.
The LM series of towers are powder coated with glossy blue finish for corrosion
resistances and aesthetics. These light masts are mounted to standard trailer hitch
mounts found on a variety of vehicles. A 44" wide and 2" by 2" by 1/8" thick
mounting plate is attached to the upper section of the mast which provides a
strong and stable platform for mounted light fixtures and equipment.
The LM family of telescoping towers feature a proprietary mast guidance system,
which provides increased stability during high winds. When lowered to 12 feet, the
mast can withstand winds up to 125 mph. The mast can be positioned in one of
four different directions, and locked back in place by re-tightening the T-handle.
This light tower weighs approximately 315 lbs and can easily support and lift 150
lbs fixtures. The entire tower assembly is shipped via common freight carrier and
when shipped measures approximately 16.5 feet long, 4 feet wide, 5 feet tall and
weighs approximately 1500 lbs. Larson Electronics can custom tailor these units to
the customer`s requirements with longer sections and different sized trailer
hitches. We also offer a choice of manual 1,200 lbs hand winches instead of the
2,500lbs electric winch.
Suggested Applications: Temporary lighting, construction sites, and security
camera deployment. We can equip this mast with 1000W or 1500W Metal Halide
lights or a wide variety of high powered LED lights with comparable power,
including the LED10WSA-160, LEDLB-200X2E, LEDLB-160X2E or LEDLB-80x2E.
At Larson Electronics, we do more than meet your lighting needs. We also provide
