Next generation lifting systems

7 April 2021

Considering an advanced industrial context, where more and more frequently the need for high speeds and continuous operations, as well as load and positioning control, the designers evaluate with great interest solutions with higher performances, easier to control (position, load and speed), and able to guarantee a competitive advantage in terms of quality and quantity of the work performed.

Based on this evolution, Servomech promotes a new concept in lifting systems, with an innovative approach, focused on the application of its high-performance ball screw jacks, with brushless motors and related drives and controls. Customers and designers are free to choose the brand of motors and drives they prefer.

The next generation of lifting systems proposed by Servomech allow you to reach high linear speeds, high dynamic operations with relevant acceleration and deceleration, high positioning accuracy, exact position repeatability and operations with a continuous duty cycle. The synchronism between the various lifting points is carried out in the electrical axis, with the control in position or in both position and torque. The use of ball screw jacks equipped with servomotors, absolute multiturn encoders and drives capable of managing the motion capability of the motors and the control of the required current, allow for reaching high speed, precision and repeatability performance.

The traditional lifting systems are in low linear speed applications, with intermittent operating cycles, preferably with the use of acme screw jacks. Through different configurations depending on the needs and dimensions and through the mechanical connections with connecting shafts, mechanical couplings and motion transmission reducers, the screw jack with motor transmits the movement to the other lifting points through a mechanical synchronism. This solution has some limits, mostly related to linear and rotation speed, inertia masses involved and the lost power in the various transmission components, vibrations, noise and play that can be created between the mechanical connections, and the uncertain accuracy of the positioning of the various lifting points.

The new generation of lifting systems proposed by Servomech therefore broadens the application horizons of lifting systems in general with a modern and advanced approach. Lifting systems can now be used for continuous operations, for process functions, with also heavy load working cycles, with highly dynamic conditions, high speed, high accuracy and control.
