HYDRAULICS 34 HYDRAULICS & PNEUMATICS January/February 2020 www.hpmag.co.uk R+L Hydraulics GmbH has introduced an expanded series of aluminium oil reservoirs. The hydraulic reservoirs with nominal sizes from NG 3.5 to NG 130 have usable volumes ranging from 3 to 123 litres. The oil reservoirs are made of cast aluminium and easy to handle and stack due to their low weight. Besides their outstanding cooling efficiency, the tanks offer an excellent price-performance ratio. The largest series production cast aluminium reservoir currently available on the market is the hydraulic reservoir with nominal size NG 130 and a usable volume of 123 litres. Given the calculated thin-walled design of the reservoir, this model has a cooling capacity of 2.1 kW at an ambient temperature of 40degC. Therefore, in many applications an oil cooler is not needed. Due to its low weight of just 25 kg, even the largest aluminium reservoir is easy to handle. Stackable All reservoirs of the series are stackable, offering corresponding economies of storage space. The oil reservoirs can be fitted with oil level indicators and filters for filling and venting. They are available optionally with or without cast iron feet and castors. Baffles can also be installed. Besides the standard range, R+L Hydraulics also offers special reservoirs made of aluminium and steel, which may be prepared with special coatings depending on their intended field of use. In addition to oil reservoirs, R+L Hydraulics develops, engineers and produces a broad range of components for fluid and power transmission technologies, including industrial couplings and hydraulic accessories such as test couplings, jaw couplings, bell housings and cooler bell housings, damping elements, heat exchangers and coolers. The products are used in a wide range of applications in machine building, shipbuilding and automotive, energy and environmental technology, in the steel and offshore industries and plant engineering. The UK distributor is jbj Techniques Ltd. www.rl-hydraulics.com www.jbj.co.uk R+L Hydraulics cast aluminium oil reservoirs for simple handling Middle Eastern heavy lifting company, Al Faris Group, has used an Enerpac SBL900 hydraulic telescopic gantry for offloading over-sized oil refinery equipment during transportation from Jafza Port, Dubai to storage at Dubai World Centre, UAE. As part of an oil refinery project, Al Faris was contracted to provide the complete logistics from loading to transportation. This involved 12 axle heavy transport vehicles as well as self- propelled modular transporters (PST/SL-E trailers) and finally offloading with the Enerpac SBL900 gantry. The refinery column’s three sections were up to 10.4m in height, 30m in length and 9.5m in width and weighed up to 315 tonne. For the offloading process, one of the challenges was the confined space Al Faris had to work in along with the tight timescale and lifting precision needed. Another challenge was the need to engineer a customised platform using steel mats to reach the required lifting height for the gantry. “The Enerpac SBL900 gantry system was the perfect fit for this job, allowing us to get the work done with utmost efficiency,” said an Al Faris spokesperson. High-capacity Enerpac SBL900 The Enerpac SBL900 folding boom, telescopic, hydraulic gantry, is equipped with two stage lifting cylinders, enabling lifts up to 11.3 m and can handle loads up to 604 tonnes at the top of the second stage. The SBL900 gantry’s lifting features include an octagonal boom providing added strength for increased capacity and lifting height, and mechanical locking permitting load holding for extended periods of time. In addition, self-propelled tank rollers provide synchronised travel in a smooth continuous manner while ensuring optimum load distribution. The gantry’s foldable boom enables easy transport and setup. Self-contained hydraulics Self-contained hydraulics allow easier setup and eliminate trip hazards that can sometimes be associated with hydraulic hoses. The SBL 900 gantry’s control system allows users to operate the lift locally at each leg or use the Intellilift remote control. The wireless system ensures continuous control and monitoring of lifting and travel operations while providing complete visibility of the load. www.enerpac.com www.alfarisgroup.com Enerpac Gantry for Al Faris petrochemical heavy lift project Al Faris uses Enerpac SBL900 gantry for petrochemical heavy lift project.
