The new MJ joystick controller from AUTEC allows the operator freedom not possible with pendant cables or fixed control stations. It is suitable for the control of tower cranes, overhead cranes and monorails, concrete pumps and forestry machines. The MJ controllers are distinguished by their compact size and ergonomic design. The cases of the transmitter and receiver are made of impact-resistant composite material with high strength, thermal stability and excellent resistance to environmental and chemical exposure. The neutral-position monitoring of actuators is used to double-check all commands, and protects them against unintended operation to category 3 (EN 954-1). The redundant and self-checking Stop utilises passive monitoring for Fail-Safe security to category 3 (EN 954-1) and active monitoring for fast reaction time.
