The Larson Electronics LM-21-9.1-4S-EW fixed mount 4-stage light mast provides a safe

and effective way for operators to quickly deploy lights, security cameras and other

equipment to elevations up to twenty-one feet. This stationary light tower features a

rotating boom that allows for 360° of rotation and a removable mast head for storing

mounted equipment when not in use.

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 21` for effective coverage. This light boom can be extended to 21`

for maximum area coverage and collapsed to 9.1` for applications where a

footprint smaller is required. The tower is constructed of square steel tubing with a

lower section 6.18` in length and 10" by 10" by 3/8" thick, second section 6.27`

in length and 8" by 8" by 3/8" thick, third section 6.45` in length and 6" by 6" by

3/8" thick, and an upper section 8.45` in length and 4" by 4" by 1/2" thick. Each

section has 2` of overlap. The mast is extended to its full height via using an

The LM series of towers are powder coated with glossy blue finish for corrosion

resistances and aesthetics. These light masts are typically mounted to trailers or

other stable surfaces via a 28" by 28", 1/2" thick mounting base-plate which has

been drilled to accept six 1-1/4" anchor bolts. Two 3" by 6" by 1/4" thick skid

pockets at the base of the mast aid in transportation and installation of the mast.

When fully collapsed, the top stage has 24" extending from the second stage,

allowing operators to mount larger equipment without having to dismount when

collapsed.

The LM family of telescoping towers feature a proprietary mast guidance system,

which provide increased stability during high winds. When lowered to 9`, the mast

can withstand winds up to 125 mph. When elevated to its full upright position, the

mast can be rotated a full 360°. By loosening the T-Handle, operators can rotate

the mast with easy in either direction. The mast can be positioned in any direction

and locked back in place by re-tightening the T-handle. The mast itself spins freely

with easy, and can typically be rotated with a single hand.

The electric winch on this mast is offered in 120V or 240V AC 50/60 HZ. Additional

voltage options are available at an additional charge. Larson Electronics can offer

single phase and three phase AC winches, or low voltage DC winches.

This light tower weighs approximately 1,200 lbs, can easily support and lift 1,500

lbs. 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 2000 lbs. Larson Electronics can custom tailor these units to

the customer’s requirements with longer sections and larger mounting plates. For

example, the LM-30-3S is another model that reaches to a length of 30 feet, with

a 14 foot lower section, 12 foot middle section, and a 8 foot upper section and a 4

foot wide upper mounting bracket. We also offer a choice of either the manual

1,000 lbs hand winches included standard or optional electric winches.

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.
