Inverter : smooth transitional speed
The dual speed inverter delivers smoother movement than the pole change motor, reducing load swing. The high to low speed ratio can be set to a large value. This results in smooth starts, improved low speed stops, and improved positioning accuracy. The standard speed ratio is 6:1.
A No-load High-Speed Function is equipped as standard feature, allowing its hoisting speed, 1.3 times faster during no-load operation. When the no-load condition is detected by the inverter, this function is activated automatically to switch to high-speed operation, leading to improving the work efficiency with ease and safety. This function is easily activated (ON/OFF) with the push button control.
EQ Hoist/MR2Q inverter unit is well-customized for lifting/traversing applications including exclusive software with optimum control and is also provided with measures against impact and heat which were verified through long run tests
The push button control is designed in an ergonomic shape that is operator friendly. Seeking ease of operation and universal design, KITO’s original push button control is designed and manufactured based on trial and error repeated many times, in particular, upgrading prototypes and evaluation from an enduser point of view especially with respect to unit strength.
Contoured to comfortably fit into your hand. The button has a light operating sensation which responds to fine adjustments in pressure. The pressing stroke is short. The operator, therefore, will not become fatigued after longperiods of operation.
Electronic overload limiter & friction clutch & upper-lower limit switch
Maintaining safety is the most important task for lifting equipment, and is essential for stable operation. To ensure safety, KITO utilizes a triple safety mechanism consisting of an originally developed electronic overload limiter and friction clutch and upper-lower limit switch. When the inverter detects an overload, the electronic overload limiter turns off the power to the motor to stop lifting the load.
The friction clutch is an emergency overload protection device that idles the motor when subjected to an excessive load over the rated capacity. Friction clutch performance is not easily compromised with changes in the surrounding temperature. In the case of irregular loading, this operates in advance to prevent the hoist body or load chain from being damaged.
In the event that a load is lifted or lowered excessively, the limit switch stops the motor, preventing hoist or load chain damage. (Not regular use)
Electronic thermal protector
To prevent the motor from burning out due to excessive usage, a standard thermal protector is installed in the inverter.
Pull rotor type drum brake
With a rotor and pull rotor incorporated in the motor, this is a cone type drum brake which is released at the time of operation. When the power is shut off, the brake is activated, ensuring safety
Emergency stop
The emergency stop, provided as standard, allows the motor power to be disconnected in an emergency without cutting off the main power supply
