Sindrilla is here to combat HAVS

Castle & Pryor have launched a product to eliminate Hand Arm Vibration Syndrome (HAVS) - also known as ‘white finger’ caused by exposure to vibration. Anyone who uses hand-held power tools for a significant length of time is at risk. And until now, there has been no real hands free solution to nerve damage and HAVS when using conventional rotary percussive drills within the construction industry.

Rotary percussion (RP) drilling combines a rotating and percussive or ‘hammering’ action in the same drill. This method is widely used across the construction industry because it’s a cheap and effective way to anchor steel frames into the ground, to drill rough sided holes into concrete, or when you need to connect one concrete slab to another using reinforced steel dowels.

When it comes to reasons why construction workers develop HAVS, rotary percussion drilling is one of the biggest culprits. Those who operate hammer action tools for 15 minutes a day are still considered medium risk. You can use the HSE’s free Hand Arm Vibration exposure calculator to work out an individual employee’s total exposure.

Castle & Pryor currently have the drill on trial with Morgan Sindall, at London Heathrow Airport. Morgan Sindall’s team are using the drill to pin shuttering to existing concrete. Here’s what Andrew Swann, Morgan Sindall’s Aviation Project Manager had to say about Sindrilla:

“I see the concept of this machine as an innovative solution to completely eliminate HAVS exposure to the operatives who carry out the PQ pan drilling task. On an airfield project, this task can account for anything up to around 50% of the total time of exposure to HAVS - so this will help us to significantly reduce the risk of operative exposure within a project.

"The unique design is quick and easy to manoeuvre around, meaning that a high number of holes can easily be drilled in a shift. The built in dust vacuum extraction unit also significantly reduces the exposure to and risk posed by silica dust.

"All in all, this piece of kit eliminates exposure to hazards of occupational health whilst still being efficient and effective. Hopefully, we can also apply this design and modify to suit other standard tasks to keep reducing the risk of occupational health hazards on our future projects.”
