Komatsu Excavator Cab Protection

Excavator cab guarding protects Komatsu operators running mulchers, hammers, augers, and log processors. Heavy Equipment Armor builds bolt-on and ballistic guarding for the Komatsu PC lineup using your factory mounting points, so you get excavator cab protection without cutting into the carrier.

What’s In the Package

Three systems make up the lineup, and most owners run more than one together:

Defender Ballistic Window	Bolt-on Excavator Screen	Bolt-on Top Cab Guard
UL752 Level 1 rated polycarbonate, bolts over factory locations on the front of the cab.	2×2″ woven wire screen, bolts on, follows the windscreen’s contour.	Shields against falling debris, lets light through, includes an escape hatch on applicable models.

Every piece is part of a complete excavator cab guard setup, installed with hardware Komatsu already put on your machine. See full builds in our product gallery.

Ballistic-Rated. Not Bulletproof.

Nothing is bulletproof, and the Defender Window isn’t “ballistic glass” either. True ballistic-rated glass at this protection level runs nearly three inches thick, too heavy to mount on a cab. HEA’s polycarbonate does the job at a fraction of that weight, bonded to a steel frame instead of drilled, so it resists the micro-fractures that crack aftermarket guarding over time. Here’s how it’s rated:

Spec	Detail
Rating	UL752 Level 1
Tested against	124 grain, 9mm FMJ, 15 ft
Temperature range	-26°F to 120°F
Construction	Bonded to steel frame, not drilled or milled
