MEYCO Piccola – GM

Concrete spraying machine
MEYCO Piccola – GM
Solutions for tunneling and mining
Expanding hor izons underground
Overview
MEYCO Equipment developed the first rotor-type machine, the MEYCO GM
in 1957. This was a breakthrough in pneumatically transporting dry-mix
sprayed concrete (also known as shotcrete or gunite) and other dry materials.
The MEYCO Piccola and MEYCO GM are the modern versions of the original
machine and they still operate according to the now very widely used rotor
principle. They are robust, require little maintenance and are simple to operate. They are so versatile, that they can be used for all types of dry shotcreting
work. The MEYCO Piccola is a smaller version of the MEYCO GM and both
machines can be custom equipped to your specific requirements and budget.
Features
➊Exchanging wear parts
or converting the machine
to other outputs can be done
without special technical know-how thus avoiding downtime etc.
➋ All wear parts are freely
accessible and outlet
assembly can be removed,
and refitted within seconds.
➌ Special self-levelling,
single-spindle clamping
system applies uniform
pressure to all sealing
surfaces.
Rubber pads and friction
discs can be refaced
several times.
➍ Machines available in electri cal, diesel and air powered versions!
➎ Belt drive protects the gear
box and motor for additional
safety.
➏Pneumatic tyres with guide
fork and towbar assure
optimum manoeuvrability.
➐ Operation via remote control (option).
➑Feed hopper with vibrator (option) rests on 4 resilient (shock-absorbing) elements and includes built-in sieve
for safety.
➒ Daily cleaning work is very time efficient thanks to the
one-spindle clamping
system.
Huge range of nozzle sizes, shapes and materials for all applications and conditions.
