Installations, decommissions and relocations of heavy machinery
- UK & worldwide.
Auditing Existing Installation
When relocating production lines or complex interconnected machinery, auditing an existing installation plays a vital role as it lays the foundations for a vertical start up.
Typically the audit consists of the following:
- Power requirements
- Heights and levels
- Vital measurements of the footprint
- Alignment issues
- Damage reports
- Maintenance issues
We view the machinery in production to gain a greater understanding of the machinery and the end product.
Also this allows us to take certain readings:
- Voltage
- Current
- Temperature
In addition, we use photographs and video footage to highlight discrepancies and aid the installation.
Once an audit is completed we can then inform our customers of any potentially adverse issues prior to relocation.
De-commissioning & removing your equipment
Once the machine(s) become the responsibility of RJB our removal team of highly experienced electrical & mechanical engineers, study the audit notes to ensure nothing has been overlooked. They isolate and disconnect any site services, make the remaining supply safe and record useful information on the removal document.
With the machines isolated from site services the team then set about any interconnections from adjacent machines, electrical cabinets or hydraulic power packs, taking care not to misplace any fixings and label all cables and their locations, creating a comprehensive document for reference when installing the machinery.
The separated machines are moved to a storage area ready to be packed / loaded for transportation to the new destination.
Installing Your Machinery
On arrival in their new location, the machines are unloaded by our engineers, unpacked and placed into a storage area ready for installation.
The installation team refer to the audit notes and factory layout to determine the centre line and datum’s of the machines, as well as the general footprint, using laser equipment for optimum accuracy.
The machines are set in place methodically, the customer checks the position is practical and the machines are then levelled using highly accurate equipment
With the machines in place the team reconnect the interconnections using the labels and removal documentation as a reference, as well as the site services required to save dealing with additional contractors.
Vertical Start Up Procedures
To achieve the optimum 'Vertical Start Up' our engineers perform the following operations:
- Yellowing lining
- Insulation resistance test
- Static & dynamic checks
- Input & output checks
- 5 Minute shakedown
- Dry run
|
|
Yellow Lining
Yellow lining consists of our electrical engineer(s) checking all electrical connections made by other engineer(s) to the removal document and the machine drawings for clarification.
This prevents any cables being misplaced or connected incorrectly according to the drawings or original installation.
|
|
|
Insulation Resistance Test
Insulation Resistance Tests are performed to ensure that no cables have been damaged during the relocation process and allow RJB to power up all the machinery safely.
|
|
|
|
|
Static & Dynamic Checks
Static checks ensure all mechanical timings are correct. The machines are turned over by hand and watched so that critical components are not damaged by other parts of the integrated machine.
Dynamic checks ensure the machines are rotating correctly whilst being driven electrically.
|
|
|
Input & Output Checks
Input checks consist of all the electrical components that send an input to the Plc being manually forced to check that the Plc is receiving the signals.
Output checks consist of all the electrical components that are operated by the Plc are forced by the Plc to check that the components are operational and that the Plc is sending out the signal.
|
|
|
|
|
5 Minute Shakedown
Shakedown is the first time the machines run once all the checks have been completed, its purpose is to make sure all connections are tight and haven’t become loose in transit.
|
|
|
Dry Run
Dry Run is the final test of the machine before handover, it lets the customer see the machines run consistently without product and prove that there are no serious issues with the installation. Current, Speed and Temperature readings are taken at regular intervals to make sure there are no irregular readings.
Once Dry Run is complete the machines are ready to run product and we hand over the machines to the customer.
|
|
|
Supporting Live Operation
On any relocation project RJB offer live operation support, where one of our engineers will remain on site after the relocation and dry run is complete.
Our engineer will assist the customer's own team to fine tune the machinery, undertaking tests to ensure the smooth operation and successful output of product.
Live operation support can also mean engineering changes once the machines are up and running to their original state.
