Problem solved:

Redesigning the SmartROC D65 breakout cylinder

Here are some of the improvements:

One piece barrel

The existing barrel was a welded assembly of multiple components, which presented inherent risks of cracking and internal leakage. Our new design utilises a fully engineered and metallurgically checked cast one-piece unit, which is stronger and more durable.

Threaded head gland

The original head gland was an interference fit and retained by a locking wire. This assembly was cumbersome to work with; it needed special tooling and would commonly seize inside the bore causing issues. Our new threaded head gland screws in and out effortlessly with the correct tooling. We also added gland and piston locking screws as an added failsafe mechanism.

The result

A durable component that is simpler to service in the field, saving time and money for the customer.

This is one of many components MASPRO has improved for superior performance in Australia’s unforgiving mining conditions.
