- Civil constructions
Mechanised shotcreting for productivity and safety
The main components of a Putzmeister mechanised concrete spraying machine – spraying arm, concrete pump, chassis and control software – are designed, developed and produced internally.
Spraying arm
Designed for Shotcrete, with a maximum vertical spraying reach of 17m and remote control operated, the robust spraying arm found in Putzmeister equipment allows the operator to carry out a smooth and accurate application.
Concrete pump
Putzmeister has been world famous as the manufacturer of concrete pumps par excellence for 60 years.
The concrete pump mounted on the equipment is specially designed for concrete spraying, guaranteeing high performance, low pulsations and a long life for the wear parts.
Robust chassis
The chassis is designed to meet underground demands and made of high resistance steel to stand the harshest working conditions. Its 4 wheel drive, 4 wheel steering and crab-mode provide maneuverability in difficult driving situations.
Its excellent climbing capacity and great ground clearance facilitate off-road driving.
Control system
The Putzmeister control system monitors the correct relation of accelerator dosage and concrete being pumped. In addition, it manages the correct functioning and security of the concrete pump. Finally, it collects the spraying data for download and processing.
Additive pump
To obtain the early resistance you require, you will need to accelerate the hardening of the concrete with accelerators. To ensure that the dosage is in line with the concrete flow at all times, the Putzmeister dosing device automatically synchronises with the concrete pump.
On-board compressor
Despite theis compact size, our concrete spraying equipment includes the option of an air compressor built into the chassis, which endows it with high mobility and the option of autonomous operation, an added value which is highly demanded.
Concrete transport
When it comes to transporting your concrete to the underground spraying site, Putzmeister offers a robust range of low-profile mixers. These heavy duty concrete mixers provide great traction and driving capacity, and come equipped with novel features that boost workplace efficiency:
A diesel engine with an Automatic Altitude Compensation (AAC) system that enables its operation at high altitudes, all while offering the same performance.
The Integrated Continuously Variable Drive (ICDV) with geared motor has electronically controlled continuous variation and ensures the correct relationship between engine torque and speed, reducing fuel consumption and noise levels.
