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.
Overview
➊ Exchanging wear parts or converting the machine to other outputs can be done without special technical know-how thus avoiding downtime etc.
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 oper-ate. 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
➍ Machines available in electri- cal, diesel and air powered versions!
➎ Belt drive protects the gear box and motor for additional safety.
➏ Pneumatic tyres with guide fork and towbar assure optimum manoeuvrability.
➐ Operation via remote control (option).
➑ Feed 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.
