A brief description of the System

Underfloor lifting systems are used to lift railed vehicles for maintenance.
The hall floor must be freely passably during and after maintenance and when the inspection pits are not desired for safety issues. The train will be lifted to allow working on the underside.

The lubrication requirements resolved by Dropsa
The spindles have to be lubricated with grease during the lifting and lowering procedure.


Parts used in the DropsA system

– Bravo pump with SMX Dividers
– Control of the system is done handled by the control panel of the lifting plant.
– The example equipment lubricates every 20 minutes of the lifting/lowering procedure for 5 minutes. No soon than 20 minutes later, the next lubrication cycle will be started.
– Future systems include on customer request, an automatic control and monitoring of the Bravo pump via an Ultrasensor on the SMX Dividers for immediate problem diagnosis.
– Using a proximity the quantity of grease can be defined more accurately and the lubricaition is guaranteed.
