The Hurricane drop hammer HD3700 is a high-production
and low-maintenance attachment for breaking concrete.
Manufactured by Universal Impact Technologies, Inc. The HD3700
is easily connected to a skid steer or an excavator and efficiently
breaks concrete in industrial tear-outs, as well as parking lots, curbs,
roads, runways, aprons, and sidewalks up to 10 inches thick.

• EASY OPERATION reduces operator error and fatigue. The
operator simply guides the skid steer in a straight line – and
does not aim or continually reposition the hammer.
• SHOCK-FREE ground engagement platform system keeps the
HD3700 grounded and focuses the shock into the concrete.
• COMPACT DESIGN, light weight and easily transported.
• SIMPLE CONNECTION allows for easy attachment changes.
• LOW MAINTENANCE and minimal wear items enhance
productivity.
• HIGH PRODUCTION due to the striking surface’s broad face
and coverage area.
• LOW INVESTMENT and high-volume production results in the
lowest cost per yard ton of broken concrete when compared to
traditional hydraulic hammer production.

THE HD3700 ADVANTAGE
• Highest impact-to-weight ratio in the industry.
• The bolt-on-ground engagement end plate makes
maintenance accessible and easy.
• Low maintenance because there are no points, bushings,
seals and accumulators to replace.
