CONTROL
SYSTEM
The THYROMAT range of drives is used to control crane hoist and travel motions using slip-ring motors.
The controller is well suited to heavy duty and continuos operations in extreme environments.
THYROMAT digital crane control delivers leading thyristor control technology to a new generation of crane
drives. It is the natural successor to MH Automation’s very successful THYROMAT analogue crane drive.
Solid state electronics allows a compact design with enhanced reliability. Self-monitoring further improves
system safety and reliability. Software features and all hardware components are engineered to meet the
requirements for both new and existing cranes. THYROMAT digital crane control makes crane operation
simple, safe, precise and consequently more productive.
MH Automation’s experience and know-how of crane applications combined with digital technology and
thousands of man-hours of engineering and design has resulted in a unique, robust and reliable product.
Designed specifically to operate in the tough environments of steelworks THYROMAT digital is a robust
crane controller suitable for all types of steelworks cranes. Table 1-1 details the special features of the
THYROMAT.
