Changing a flat tyre on heavy machinery is one of mining's most hazardous and time-consuming maintenance tasks, often taking up to 12 hours to complete in confined spaces with sloped surfaces - and especially in underground operations.

It's such a well-known problem that some manufacturers began selling underground machinery with in-built jacks, but this poses a significant extra cost to the end-user.

To solve this problem, Enerpac partnered with engineering and fabrication specialists CME Boilermaking to create a product that allows manual jacking of the vehicle for safe and reliable lifting and maintenance.

CME's underground jacking system comprises of an Enerpac XC-Series cordless hydraulic pump, connected to an RAR-Series durable, lightweight aluminium cylinder, which can handle loads up to 100 tonnes. These are integrated into CME's custom-fabricated lifting plinths and pedestals, which are designed to optimise stability and safety.

"The lightweight cylinder and battery pump are crucial elements in our underground jacking system. With sloped or rough surfaces and limited space, once a huge mining vehicle has reversed down the track, no other vehicles can access it to perform maintenance tasks," explains Mr Peter Camarri, Managing Director, CME Boilermaking.

"There's also no power source down there, so air or mains electrical options are ruled out. The Enerpac battery pump is the perfect solution. The battery power means that it can operate underground, and not having cords adds to the safety of the operators," said Mr Camarri.

"Once a mining vehicle gets a flat tyre, the chassis is essentially on the ground, which means that many conventional lifting devices are not an option. The entire lifting system had to be under 25kg so that it was as light as possible to manually carry to the vehicle."

Compact cylinders deliver safety and simplicity

Enerpac has a comprehensive range of time-saving compact hydraulic cylinders which are also ideal for maintenance and repair works in confined spaces. Its latest RLT-Series Single-acting Cylinders come in capacities from 4-74 tons, with collapsed heights of 45-114mm. They feature two or three pistons and can lift loads up to 40mm in a single movement.

The Enerpac new low-height RLT-Series Telescopic Cylinders are especially designed for applications where a longer cylinder stroke is required in a confined space.

Nitrocarburized surface treatment inside and out provides unparalleled sideload resistance and corrosion protection for safe use in the harshest conditions. The longer stroke length of telescopic hydraulic cylinders saves time and simplifies projects by moving a load a greater distance and eliminating the use of temporary cribbing.
