Outline
High speed, high frequency, and high efficiency operation increases productivity and contributes to energy saving and environmental measures. The jack can be used not only for ordinary lifting, but also for various purposes.
Features
-
Capacity: 5 kN ~ 50 kN
-
Lifting screw speed: Max 20 m/min
-
Compared to the ball screw jack, it is 5 times faster.
-
Duty cycle: Max 70% ED
-
Has 5 times duty cycle compared to the conventional product.
-
Input rotation speed: Max 2000 ~ 3000 min⁻¹
-
Can be used for wide-ranging operations by utilizing a servomotor.
-
This type of jack does not have a self-locking function, so it is required to install a brake.
