The remedy for damaged roads

Blow-Patcher patch machines

The schäfer-technic Blow-Patcher is a state-of-the-art machine that meets the technical requirements for practical operation on the building site.

The arm with mixing head is an ergonomic tool for repairing localised damage such as potholes. The machine has reservoirs for chippings, binding agent, water and air, which are metered through the mixing head using a computer.

Continuous development of the machinery and metering control guarantees a consistent and reproducible mixing quality.

Special materials are used which minimise wear and maintenance, thereby ensuring the machine is ready for deployment at all times. The design was mainly focused on intuitive and convenient handling of the machine.

To increase the safety for operating personnel, the arm with mixing head can be installed in front of the truck. In this case, the user can conveniently control and operate the boom from the driver cab using a joystick.

The working method using the schäfer-technic Blow-Patcher provides an efficient solution with high quality.

The machine can be used independently of the asphalt surface. It offers high performance and enables precisely targeted delivery of the mixture to the damaged area. Thus, the schäfer-technic Blow-Patcher supports you in achieving your objective of using materials and resources sparingly.

The fast working method also allows fast reopening of the repaired area for traffic.

REPAIRS TO DAMAGED AREAS

Potholes, frost heave, sinking, eruptions at the edge of the road surface, thinning of the top covering, network cracks in asphalt surfacing and pavement damage can all be repaired with the right machine. Optimum repairs permanently eliminate the damage and maintain road safety. The road surface can also be prepared for further work (e.g. surface treatment).

In addition to the Blow-Patcher, schäfer-technic supplies repair trains and the Mini-Mix for repair work.
