Operating Sleeves.

Similarly to long travel MLRMs, the RLRPs may need to be rotated (via the RD93 / RD91 drive) whilst being observed at the probe end. For long travels, two people will normally be needed.
To overcome this problem we offer an extension sleeve that clamps to the end rotary drive and extends all of the way down to the main body housing. It is set on bearings and enables rotation whilst still being comfortably near to the probe end of the drive. Consider ordering the extension sleeve with any long travel RLRPs as a matter of course. Order the appropriate part code as listed below.

Motorisation

We use motorised RD91Ms for both of the rotational axes when motorisation is required on the 2 Series, and a RD91M (rotation) and a RD6 (linear movement) on the 6 Series. (Please note the torque limitation specifications). When motorisation is required please note we recommend factory fitting of motorisation to the LRPs or RLRPs. Remember that a friction brake will also be required if the unit is to be mounted for vertical operations.

Electrical Services

For special applications, it is possible to add a set of wires to the end of the LRP/RLRP to give the probe end a current / signal carrying capacity. The wires can be either designed to carry current or signals (such as Thermocouples).

Microswitches

It is possible to fit a microswitch assembly to a motorised LRP6 or RLRP6 version (without the operating sleeve). The limit switches are set to indicate when the probe is either fully extended or fully retracted. The microswitches are intended for use on automatic systems as a safety interlock.

Vertical Mounting

It is possible to mount the LRP or RLRP in a vertical position. The only thing required is a friction brake on the rotary drive to stop the linear drive winding down under the force of gravity. This brake can be ordered as an optional extra at the time of manufacturing the LRP/RLRP or added at a later date as an extra.

Important - Always remember to mount the drive such that any system breakage would cause the drive assembly to fall back into its housing and not into the vacuum system.
