VK 1240S Paving Breaker-88lb

Paving Breaker – VK 1240S ( 88 lb )

The VK 1240S is the silenced VK 1240, technically equivalent to the Chicago Pneumatic CP 1240S. The 67 mm bore and 158 mm stroke deliver the same 1,150 blows per minute on 38 l/s of air, with a muffler for demolition close to occupied buildings. It takes the 32 x 160 mm shank common to the heavy Vikay breakers, so tooling is shared with the 117 and 1230 models.

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 1240S Paving Breaker FAQs

Can the VK 1240S replace a CP 1240S?

Yes. The VK 1240S is technically equivalent to the Chicago Pneumatic CP 1240S, manufactured by Vikay in India. A 67 mm piston on a 158 mm stroke gives 1,150 blows a minute at 40 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.

Which Vikay paving breaker do I need?

This page is the VK 1240S at 40 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 1240S?

The VK 1240S 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 size the compressor against that figure rather than against a peak.

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

The VK 1240S 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. Measure the shank on your existing tools rather than going by the model number.
