Two HPUs and Ten Jacking Cylinders Manufactured for New Client

Earlier this month, Rotec Hydraulics completed a large project for a new customer who specialises in all aspects of confined space working from sewer rehabilitation, timber headings, tunnelling, grouting, all types of shaft sinking and associated clean and waste water works.

With a wealth of experience constructing shafts up to 30 metres in diameter and to depths of 35 metres, the specialist construction company sink shafts using various techniques – including hydraulically jacking segmental shafts vertically.

Rotec were asked to design, build and deliver ten hydraulic cylinders and two hydraulic power units (HPUs) capable of powering 40 tonne hydraulic jacks with up to 210 bar pressure for a significant shaft sinking project.

The HPUs operate ten hydraulic jacking cylinders using ten off detented levels and a single sprung loaded dead man’s lever. The jacking cylinders have a 160 bore, 110 rod, 1200 stroke and are mounted in frames which push down concrete segments to line holes. Each cylinder can provide up to 40 tonne force with 210 bar pressure which can be controlled by an adjustable knob on the HPU.

To speed up the extension and retraction of the cylinders, the HPUs have been designed with a two-stage pump which produces a faster flow when less hydraulic pressure is required. The pump is powered by a 7.5 kW 3-phase electric motor which is controlled by electrics mounted in an enclosure on each HPU. This allows the pump to be started and stopped easily, as well as providing essential emergency stop buttons.

Both HPUs have a 500 litre tank with pressure and return filters, in addition to a fitted level/temperature gauge. Connections from the HPUs to the cylinders are via protected hoses with quick release connectors.

To increase safety and reduce risk of harm to the operator, the hydraulic hoses on both the HPU and those to the hydraulic cylinders have been fitted with hose burst protection and whip checks where necessary.

Remote system fitted to quarry conveyor improves safety and operational control

100% Achilles audit _Rotec Hydraulics Ltd

Rotec Hydraulics have designed and installed a remote system, improving safety and operational control for our client at a significant limestone extraction quarry located within the South West of England.

Our customer utilises two tracked crawler vehicles to lift and manoeuvre a length of conveyor into position at the quarry. Previously, the vehicles had to be driven locally by personnel on the machine. To increase safety there was a request to design a system which would allow the machines to be operated remotely, keeping persons away from potential falling objects on the conveyor.

The remote system has additional benefits – including improving efficiency and the communication between machine operators because they can now stand next to each other and tandem lift with greater synchronisation. Previously they would be at opposite ends of the conveyor and this would require multiple banks-man and hand signals.

Rotec’s technical team and engineering team designed and fitted a new control system based around a Parker IQAN mobile specific safety controller which uses CAN Open protocol to safely communicate with a radio remote system.

Existing manually operated valves were exchanged for electronic proportional control, allowing the operator to drive all the hydraulic functions remotely that were previously only available using hydraulic levers locally on the vehicle.

Backup electronic joysticks have been installed locally on the vehicle if the remote control was ever to become damaged during use, eliminating the risk of the vehicle becoming stranded in this rare scenario.

Our customer requested we fitted their own specific blue warning lamps and white noise sounders, all of which are driven directly from the new safety controller.

The existing emergency stop system was removed and replaced with an updated dual channel fail safe circuit featuring safety relays, bringing the equipment up to modern safety standards. Emergency stops include one located on the remote control allowing the operator to stop functions quickly and safely from a distance.

The newly installed Rotec control system integrates with the existing engine controller to allow warning messages to be displayed on the screen located on the remote, providing the operator with ultimate feedback if any engine faults develop during use.

Rotec also installed a Bluetooth modem allowing the customer to make certain parameter changes to the control system using a free app that is available to download.

The app enables any user to view logs, check the health of the system and monitor various sensors all wirelessly from a smartphone or tablet. Additional features include the ability to connect the machine to the internet so Rotec staff can remotely assist, diagnose and install software updates if required. Password protection has been employed to prevent abuse of the system by anyone except personnel issued with the login credentials.

To integrate with the client’s corporate branding, we customised the remote control with the client’s logo. Customisations such as switch positions and labeling were also discussed and agreed with the customer before build to ensure we delivered the best customer service and client satisfaction.

Rotec Hydraulics receives ‘Lifetime Supporter Award’ from the British Fluid Power Association (BFPA)

Last month, Rotec Hydraulics proudly welcomed the British Fluid Power Association (BFPA) to their headquarters in Taunton, Somerset to be presented with a BFPA award.

The esteemed Lifetime Supporter Award by the BFPA recognises our commitment, dedication and support to the British fluid power industry. The award also celebrates Rotec’s special and longstanding relationship with the BFPA.

Rotec Hydraulics was a founding member and key player in the development of the BFPA, which is now in its 65th year. As a founding member, we played a pivitol role in setting up the UK’s only trade body for the Hydraulic and Pneumatic industries.

Rotec’s Managing Director, Paul Prouse, comments,

“Rotec Hydraulics was one of the founding members of the BFPA 65 years ago, and it is a privilege to continue our involvement. The BFPA plays a crucial role within the industry for standards, legislation and training and we are proud to continue to support and work closely with the BFPA.”

Rotec completes innovative remote monitoring system onboard a vessel

As equipment increases in complexity, there is a growing need and advantage to being able to monitor parts of, or a complete system remotely.

With a long held commitment to innovation, Rotec Hydraulics are the first known company in the UK to have designed, installed and commissioned Parker IoT software that remotely monitors a hydraulic system.

With the ability to be installed and remotely monitor any hydraulic system, Parker Internet of Things (IoT) technology allows a user to ensure their assets are working at full functionality by monitoring key performance indicators, such as temperature, pressure and flow.

The remote monitoring technology further benefits the user by providing vital performance feedback for preventative maintenance planning, and can monitor real time and historical data all within a simple web-based interface.

This web-based portal can be accessed worldwide and gives a further benefit of GPS asset tracking and visibility – thus aiding both security of equipment and logistical transport efficiency which in turn, can reduce fuel costs.

The innovative IoT project came to fruition following Rotec being asked by a boat manufacturer to gather information about the performance of the hydraulic system they were fitting to a new fleet of vessels.

Because of the harsh marine environment, robust equipment was selected that meets high ingress protection. IoT modems are compact and have built in aerials allowing for a sealed solution, meeting strict IP67 ingress protection and wide temperature ranges of -30 to +75 degrees.

Multiple sensors were fitted by Rotec’s engineers to provide feedback of tank levels, oil temperatures, flows and pressures in various parts of the system.

A further enhancement was provided by adding a particle contamination device which monitors and uploads the vessel’s oil cleanliness data to the cloud. Previously hydraulic oil changes were performed on a time expiry basis, whereas adding sophistication of a real time oil contamination device now tells the customer when the oil needs to be changed rather than changing at estimated time intervals. This reduces both the cost for the customer and decreases the impact on the environment because they are now performed only when required.

The customer was particularly impressed as Rotec Hydraulics were able to code unique software and download this remotely to assist with additional logging during sea trials of the vessel before delivery for normal operations at sea. This provided additional information that has not previously been visible due to the nature of the testing preventing personnel being on board monitoring the systems from the bridge.

The IoT can be connected to an engine ECU using standard j1939 CAN protocol to give live engine data to be able to monitor remotely. This can provide data feedback from various sensors to ensure optimal engine performance and critically, no abuse of the equipment when being used in the field.

Alerts can be set and configured to automatically send emails once thresholds are exceeded, enhancing the effectiveness of automated data upload.

Built in Bluetooth and WiFi also allows the user to access the password protected modem locally to download logs and further enhance the remote experience. Software updates can be performed remotely over the web or by Bluetooth/WiFi to increase the functionality of the sampling controller or change data collection and upload frequency, allowing for maximum end user flexibility for the customer.

Hose Test Rigs for the Motorsport Industry

Rotec Hydraulics Ltd designed, built and commissioned two identical hose test rigs for a UK manufacturer who supplies world-leading racing teams with fluid transfer assemblies, hose and fittings.

UKCA/CE certificated and labelled, the test rigs are designed to provide regular and rigorous testing for a variety of flexible hose assemblies. The rigs were based on an existing design, but updated and improved due to the obsolescence of some of the components.

Measuring over 3 metres in length, the main capabilities of the test rigs include:

Testing hoses up to four hoses at a time
Testing hoses up to 250bar pressure using water as the medium.
An air supply is used to control the hydraulic (water) valves and is used to pressurize the water using a 60:1 air/water intensifier.
A low-pressure pump provides a means of flushing and pre-filling the hoses under test.
Clean, filtered and dried compressed air supply of guaranteed continuous pressure of 6 bar minimum.
Power supply of 240VAC 1 PH 50Hz 16A maximum for UK use.
Nominal test sequence, based on existing rigs, (i.e., prefill/flush, test, vent, purge).

Each rig consists of a grade 316 stainless-steel upper half, and a powder coated steel lower half and electrical enclosure.

The lower half consists of the water reservoir, an air tank, an intensifier, a low-pressure pump, pneumatically operated hydraulic valves and a pneumatic control system. All the valves, which water flow through, high-pressure pipework & reservoir are made of grade 316 stainless steel to prevent corrosion. There are two lockable hinged doors on the front and three lockable panels on the rear to allow access for maintenance as well as internal led strip lights for enhanced lighting.

Inside the upper enclosure are eight ½” BSP ports (four either end) to which up to four hose assemblies can be installed for testing at up to 250 bar pressure. Bi-fold doors with transparent windows are fitted to enable access to the hoses, the doors are fitted with interlocks to ensure they cannot be opened whilst the hoses are under test. Internal led strip lights are built into the top of the enclosure to provide enhanced lighting. There is also a water filling point and drain which connect to a reservoir in the lower half of the rig.

Attached to the right-hand side of the rig is the Rotec designed lockable electrical enclosure which houses the customers electrical components. On the front face of the enclosure are controls for adjusting the test pressure, starting/stopping the testing cycle as well as an information screen displaying the results of the testing.

2 manually operated panel mountable air regulators were incorporated into the design. One is set and locked at 4.2bar inside the lower area (i.e., beyond the reach of the operator), the other panel mounted in the user control panel. This second unit is fed from the outlet of the former, ensuring the user cannot inadvertently set the test pressure to rise above the setting of the former and thus inadvertently (or intentionally) over-pressurise the system.

Rotec’s customer said:

“I am very pleased with the finished machine. As I expected, everything has been finished to a high standard.”
