The Pneumatic Pusher Leg is a robust support and thrust component designed for use with handheld and rig-mounted rock drilling equipment in mining, quarrying, and construction applications. Powered by compressed air, this pusher leg provides controlled feed force, improved drilling stability, and enhanced operator efficiency.
Engineered for demanding site conditions, the pneumatic pusher leg ensures smooth thrust application, better drill alignment, and reduced operator fatigue. Its durable construction and reliable pneumatic mechanism make it suitable for continuous drilling operations in hard and medium-hard rock formations.

The Pneumatic Pusher Leg, also known as a Jack Leg, is a compressed-air-operated support component used with compatible handheld rock drilling machines. It provides feed force and supports drill positioning during drilling operations in mining, quarrying and tunnelling applications.
The DRILLMAN DM 051 is intended for drilling arrangements where controlled forward movement and suitable equipment support are required.
A jack leg operates using compressed air to extend its supporting mechanism and apply thrust to the connected rock drill.
During operation, the leg supports the drilling machine while the operator controls its positioning and feed. The arrangement allows the drill to advance as the drilling tool penetrates the rock.
The suitability of the equipment depends on the rock drill model, working position, compressed-air supply and operating conditions.
Compressed-air-operated support mechanism
Provides feed force during drilling
Supports drill positioning
Intended for compatible handheld pneumatic rock drills
Used as part of a rock drilling arrangement
This equipment is intended for rock drilling operations in environments such as:
Underground mining
Quarry drilling
Tunnelling
Rock excavation
Other compatible pneumatic drilling applications
The operating arrangement should be selected according to the drilling task, available working space and machine compatibility.
The DRILLMAN DM 051 has the following specifications:
| Parameter | Specification |
|---|---|
| Weight | 19 kg |
| Length | 1820 mm |
| Extension Length | 1300 mm |
| Piston Diameter | 53 mm |
| Hose Connection | 12.5 mm |
These dimensions should be considered when evaluating the equipment for a particular drilling arrangement.
Before selecting a jack leg, buyers should review the compatibility of the support mechanism with their existing rock drilling machine.
Important considerations include the available compressed-air supply, the required working position, the dimensions of the equipment and the type of drilling operation.
The supporting component should also be evaluated alongside the rock drill and the drilling consumables used in the complete setup.
The DM 051 forms part of the DRILLMAN range of rock drilling equipment supplied by Swastic Drilling Company Limited.
