Automated assembly process: A control cabinet with PLC and electrical 
components is installed on the ground next to the assembly line. Process control 
buttons are displayed on the cabinet doors. Next to each assembly post, a control 
unit is installed, on which control buttons are also located. A control cabinet is 
installed on each winch. 
1) Starting the process: the responsible specialist for the assembly line presses 
the Start button on the door of the control cabinet - which means the start of the 
engines of the first winch and the beginning of its movement to the first assembly 
post according to the program prescribed in the PLC. 
2) The first crab stops at the first assembly post and stays on it until the 
completion of the assembly operations of this post. 
3) After the workers of the post have completed their work, one of them 
approaches the control unit of this post and presses the Complete button - after 
which the first winch continues to move to the next post according to the program. 
4) As soon as the first winch leaves the first assembly post, the second winch 
moves to the first assembly post and repeats the same operations as the first one
also with the other two winches and the other 4 posts. 
5) The next winch does not move to the next post until the previous winch 
leaves it. 
The project can be implemented in two formats, the choice of which depends 
on the funding budget 
1) A more budget option includes: 
• 1 PLC Mitsubishi Q02YCPO and expansion units 
• Signal transmission between the controller and control cabinets on each crab 
is carried out through signal trolleys in large numbers 
This option is feasible, but less safe, as it is usually not used in such projects 
and therefore little studied. 
2) More expensive implementation option: 
• 5 Mitsubishi Q02UCPU PLCs and expansion units (1 PLC located in the 
main control cabinet on the ground and 4 others in the cabinet of each crab) 
• The transmission of signals between the controller on the ground and the 
controllers from the crabs is carried out through signal trolls in a much smaller 
number than in the first option 
This option is used everywhere in similar projects of foreign specialists, but 
requires serious cash injections, the estimated cost of one PLC is about 20 million 
tenge. 
 
Brief project effectiveness: 
• The human factor is excluded from the assembly process in which the 
LM is involved, in the mechanical process, 1 person monitors the entire movement 
of the winch. There is a high probability of situations when the operator can hit a 
winch with a body in front of another hanging winch with a body - automation will 
reduce possible damage to products and equipment; the operator can hit a person in 
his blind zone with a winch. 
• Electricity is saved and the wear of electric motors is reduced by 
reducing starting currents: with the mechanical control of the LM, the operator
