VK 51 Pusher Leg

PUSHER LEG – VK 51 (BMT 51)

The VK 51 is a 15 kg pneumatic pusher leg, technically equivalent to the Atlas Copco BMT 51, and is the feed leg for the BBC 16W and BBC 34W jackleg drills. It is built from high strength aluminium alloys developed for aerospace use, which is how it holds a 2,985 mm extended length at that weight. The 60 mm piston gives high feed force, it is double acting so it pushes out and pulls back in, and the feed controls sit where the operator's hand already is. Used in production drilling, mining, construction and the dimension stone industry.

Application

• Production drilling

• Mining and Construction

• Dimension stone industry

Features

Technical Data

VK 51 Pusher Leg FAQs

Can the VK 51 replace a BMT 51?

Yes. The VK 51 is Vikay's technical equivalent of the Atlas Copco BMT 51, made in India. It weighs 15 kg. It is made for the Atlas Copco BBC 16W and BBC 34W jackleg drills, with 1,300 mm of feed from 1,658 mm retracted to 2,985 mm extended.

Which rock drills does the VK 51 pusher leg fit?

It is made for the Atlas Copco BBC 16W and BBC 34W jackleg rock drills. The leg weighs 15 kg, has a 60 mm piston and a feeding length of 1,300 mm, extending from 1,658 mm retracted to 2,985 mm.

Do I need a pusher leg with my rock drill?

For sustained horizontal or inclined drilling, yes. The leg takes the weight of the drill and feeds it into the hole, so the operator guides the machine rather than carrying and forcing it. Hand held work of a few holes at a time does not need one.
