Thomson LC2000 Lifting Columns

Perfect for medical and ergonomic automation applications, Thomson's LC2000 Lifting Column gives your application a simple, all-in-one solution.

Made with a three-piece extrusion, 2000 N loading capacity and a telescoping leadscrew mechanism, the LC2000 provides an ideal extension-to-retraction ratio.

This self-supporting column is made of extruded anodized aluminum. The aesthetic design requires no additional shrouding or covering.

Plus, the LC2000 has been EMC recognized for medical applications and the quiet operation meets CE standards for audible noise requirements. Protections, such as end of stroke limit switches, make this unit an ideal product for your application.

VIDEO: Synchronizing Multiple Lifting Columns >

Thomson introduces the benefits of synchronizing multiple lifting columns using a single control device. This video shows how to zero-out the encoder feedback devices on all columns - even with offset loading. Can be used in applications such as large ergonomic workstations or medical table beds.

VIDEO: Lifting Columns: Medical-Ergonomic Apps

Kyle Thomson, Lifting Columns Product Line Manager, discusses various medical and ergonomic applications for Thomson lifting columns and provides details on the many functionalities and benefits of column technology. Also include is an interview with a leading manufacturing engineer from Videojet who shares how they integrated lifting columns into their manufacturing processes to increase employee safety.

DCG Control Series

DCG Controls

Controls available for single lifting column operation or synchronous operation of two lifting columns equipped with encoders
Small and light weight control operated via a control pendant (ordered separately)
Built in Electronic Limit Switches (ELS) stop the lifting column automatically at end of stroke or mid stroke stall
No wiring is necessary to the control as all connections are done through plugs

* Control will shut off if duty cycle is exceeded and automatically reset when cooled off.
** DCG-280 monitors the encoder pulses and not the motor currents. If the pulses arrive too slowly or not at all it will stop the motion of the lifting column.
