Metabo HPT 70lb AHB 1 1/8in Hex Breaking Hammer with UVP

Description

Massive concrete bridge deck demolition destroys lightweight hand hammers in minutes. The Metabo HPT 70lb AHB 1 1/8in Hex Breaking Hammer with UVP smashes through dense cured concrete and highway asphalt with relentless force. Operating on a 15-amp electric motor, this 70-pound pavement breaker delivers 51.6 ft-lbs of impact energy. Dry firing against air without chisel resistance causes brutal piston rebound shocks that crack internal barrel stops.

An Aluminum Housing Body encloses a double-insulated stator alongside a heavy-duty crank-driven piston mechanism. The 1-1/8-inch hex chuck features forged alloy steel retaining pins engineered to lock heavy demolition steels under extreme downward kinetic force. User Vibration Protection incorporates internal dynamic counterweights alongside spring-dampened handles to neutralize destructive linear kickback. Sealed ball bearings protect internal drive gears from abrasive silica dust ingress. Degraded crankcase grease causes internal piston friction, resulting in loss of impact force and rapid cylinder scuffing.

Heavy Demolition Breaker Hardware Architecture

Highway and municipal utility crews require relentless linear smashing power without hydraulic hoses or tow-behind compressors. The mechanical crank assembly drives a heavy air-cushioned piston through an oversized anvil block.

• 15-amp electric motor delivers 51.6 ft-lbs of kinetic impact force to fracture thick roadway asphalt and concrete
• 1-1/8-inch hex tool chuck retains heavy pavement breaker steels, asphalt cutters, and tamping pads firmly
• Aluminum Housing Body technology combines metal internal durability with lightweight outer handling
• User Vibration Protection uses internal counterweights to cut vibration transfer to operator joints
• Soft-start electronic circuit prevents breaker bucking and jobsite electrical breaker tripping upon start-up
• All-metal internal gear architecture runs in a continuous grease bath for long mechanical wear life
• Heavy-duty rubber power cord jacket resists tears and oil contamination on harsh roadway job sites

Heavy Breaker Telemetry Stall Realities

Motor current pulls a continuous 15 amps from 120-volt circuits under full downward chisel immersion in 6-inch reinforced pavement. The mechanical piston cycles at 850 blows per minute. Kinetic strike energy outputs 51.6 ft-lbs per blow into cured concrete slabs. Internal crankcase compression elevates lower housing temperatures to 155°F after thirty minutes of continuous breaking. The 1-1/8-inch hex chuck withstands up to 220 ft-lbs of bending pry force. Noise exposure peaks at 100 dBA at operator ear distance.

Roadway Demolition Maintenance Boundaries

Heavy pavement breakers demand adequate electrical supply line voltage to prevent field coil burnout. Small plumbing contractors breaking thin basement tiles should not buy this 70-lb breaker because its weight and smashing power shatter underlying drainage pipes. Forcing the chisel into concrete beyond its collar depth risks jamming the tool steel permanently in the slab.

• Grease the 1-1/8-inch hex shank of every breaker steel before inserting it into the tool chuck collar
• Clean road dust and asphalt tar from the chuck locking mechanism using a solvent brush daily
• Use a minimum 10-gauge heavy-duty extension cord to prevent low-voltage electrical motor damage
