MEYCO Cobra
Solutions for tunneling and mining

Expanding hor izons underground
Expanding Horizons 
The MEYCO® Cobra is perfect for applying wet-sprayed concrete in 
mines, or anywhere where there are restricted profiles. With all the 
necessary components on one chassis and the ability to reach any 
area of a mine rapidly, it greatly increases the efficiency of not only 
the spraying operation but the mine as a whole. Within today’s tight 
working schedules it is crucial that the spraying set-up can be quickly 
installed, and ready to start performing within minutes. Immediately 
after spraying has been completed, the equipment must be removed 
so that the next work cycle can begin. Thanks to the MEYCO Cobra's 
manoeuvrability around winding tunnels, the almost seamless execu-
tion of sprayed concrete operations on several faces is simplified. The 
machine's integrated compressor is also an essential element where 
the central air supply is insufficient to meet all demands.

Additional Technical Specifications:

on request.
Important | * Pump performances including maximum volumes are based on theoretical, 100 % filling capacities. Delivery heights and distances are 
based on experience but are highly dependent on the granulometry, cement content and plasticity of the concrete.
The MEYCO Cobra is an extremely compact electro-hydraulically driven 
mobile unit for the application of wet-sprayed concrete. A complete 
system specially designed for the uncompro mising conditions found 
within the mining industry, it still retains features that ensure the 
successful application of the high-quality sprayed concrete demanded 
by our customers. This is achieved with the MEYCO sprayed-concrete 
pump, integrated with the sophisticated MEYCO Dosa TDC accelerator 
dosing system. The MEYCO Minima, a spraying manipulator developed 
specifically with small profile tunnels in mind, offers very compact 
retraction and can be extended easily within a confined space. The 
spraying head, a standard MEYCO component, is fitted as a «fold-back» 
unit, thus reducing vehicle length whilst tramming. All components are 
mounted on a 4 x 4 articulated PAUS mining chassis.

Operation and controls
 
 Display as MMI allows 
operator full control of 
dosing and pumping values 
with other vital features. 
Shows all details necessary 
for spraying operation 
overview.
 MEYCO Data performance 
monitoring, for compiling 
perfomance information for 
operation management and 
quality control.
 Main electric cabinet 
mounted on hinge to allow 
access to diesel motor.
 Remote control with main 
functions for full command 
of spraying operation, 
manipulator, air, pumping 
and dosing adjustments.
 Smooth and simple 
operational control through 
1 joystick (proportional) and 
2 levers.
Dosing system: MEYCO 
Dosa TDC 
 Total Dosing Control does 
what it says using interac-
tion of frequency controlled 
dosing pump drive, concrete 
volume and flowmeter. 
Ensures dosing accuracy at 
all volumes and pressures.
 Ideal for Alkali-Free 
accelerators. Stainless steel 
pump unit prevents corrosion 
plus dry running protection 
to protect rotor /stator.
 Stainless steel chemical tank 
and heavy duty 2” supply 
hose and camlocks for easy 
suction and attachment.
 Rotor / stator pump for 
pulsation-free operation and 
to allow accurate dosing 
measurement.
Spraying manipulator 
MEYCO Minima
 Developed especially for 
mining and tight tunnels. 
 Mine experience = optimised 
manipulator technology.
 Constructed according to 
rollover principle.
 Very compact retraction, can 
be extended easily without 
needing additional room.
 Robust spraying head is a 
standard MEYCO compo-
nent. Fitted on Minima as a 
«fold-back» unit, reducing 
the vehicle length whilst 
tramming.
 Central lubrication unit for 
entire system featuring con-
trol unit for regular supply 
and transparent reservoir 
reduces wear and mainte-
nance, increasing working 
life and value of equipment.
