VK 1240 Paving Breaker-86lb

Paving Breaker – VK 1240 ( 86 lb )

The VK 1240 is a 39 kg paving breaker, technically equivalent to the Chicago Pneumatic CP 1240. It is the heaviest breaker in the 12 series, with a 67 mm bore and 158 mm stroke producing 1,150 high energy blows per minute on 38 l/s of air. Specify it for breaking reinforced concrete, heavy road works and rock where lighter breakers stall.

Features

• Alloy steel forgings – for excellent durability 

• Four-bolt back head – withstands rugged use 

• Integral oiler – provides continuous lubrication 

• Reversible piston – reduces maintenance cost 

• Air inlet swivel – for easy manoeuvrability 

• In addition to the standard units, there are also silence versions (S models)* and versions with extra vibration dampening (SVR models)*.

VK 1240 Paving Breaker FAQs

Can the VK 1240 replace a CP 1240?

Yes, that is the duty it is made for: the VK 1240 is technically equivalent to the Chicago Pneumatic CP 1240. A 67 mm piston on a 158 mm stroke gives 1,150 blows a minute at 39 kg on 38 l/s of air at 6 bar. It takes the same 32 x 160 mm shank, so moil points, chisels and asphalt cutters already on site will fit.

Will Vikay parts fit my CP 1240?

Yes. Vikay manufactures the VK 1240, which is technically equivalent to the Chicago Pneumatic CP 1240, and the replacement parts alongside it. The same parts serve both, so a machine already in service can be kept running on them. The listing, with part numbers and the assemblies they belong to, is on the CP 1240 Chicago Pneumatic Paving Breaker Parts page.

Which Vikay paving breaker do I need?

This page is the VK 1240 at 39 kg, at the heavy end of the range. Vikay manufactures breakers from 13.5 kg to 42 kg and the weight is the job: 13.5 kg for light construction and plant maintenance, 20 to 30 kg for general breaking, asphalt and pavement, 36 kg and above for reinforced concrete, frozen ground and thick pavement. The lightest machine that will do the work is usually the right one, because a heavier breaker breaks faster but tires the operator sooner. Silenced versions are manufactured alongside most models where noise is regulated.

Will my compressor run the VK 1240?

The VK 1240 needs 38 l/s at 6 bar (81 cfm at 87 psi), delivered continuously. The inlet is 19 mm, so run at least that hose bore: anything narrower throttles the machine before the compressor does. At 1,150 blows a minute the draw is constant rather than intermittent, so allow headroom for hose length and for worn couplings.

Will my existing moil points, chisels and asphalt cutters fit the VK 1240?

The VK 1240 takes a 32 x 160 mm shank (1¼" x 6¼"), with 28 x 160 mm available as an option, so any moil point cut to that shank fits, whatever machine it came off. Order tools against the shank, not against the machine.
