Sky TV’s headquarters at Osterley in West London boasts the most sustainable broadcasting facilities in Europe
Sky TV’s headquarters at Osterley in West London boasts the most sustainable broadcasting facilities in Europe. A new complex, Sky Studios, provides 23,000 sq m of floor space for studios, offices, post-production and technical facilities, home to the company’s flagship entertainment and sports’ channels. It is home to 1,370 permanent and production staff.
The new studio complex includes a combined cooling, heating and power (CCHP) plant, designed and built by industrial and commercial bioenergy specialist, Clearpower. The CCHP plant uses wood chip biomass, from broken down wooden pallets, generating electricity and heat for Sky Studios. The plant processes 10,000 t of wood chip per year, generating 1 MW of electricity and 5 MW of heat.
To service the technology, Demag Cranes has installed a fully automated crane system. Wood chip is delivered to the CCHP plant by vehicles and tipped into a sunken input area. When sensors indicate that biomass levels require replenishment, the crane system automatically lifts biomass from the input area and deposits it into the silo store. The wood chip is then fed into the furnace, by a conveyor system, according to demand.
To meet the requirements of the CCHP application, Demag installed a 7.8 m span overhead travelling crane, incorporating a DR-Pro electric wire rope hoist, rated at 6.3 t SWL. Suspended from the hoist is a specialist 4.5 cu m capacity clam shell grab, with teeth and side knives, for optimum handling of the wood chip.
The crane has long travel speeds of 1.5 – 40 m/min, cross travel speeds of 1.5 – 20 m/min and hoisting speeds of 1 – 16 m/min for fast and efficient load handling. It features frequency inverter controlled drives, which ensure precision load positioning and minimise load sway, reducing the possibility of contact between the bucket grab and the walls of the storage area. The system also includes long travel and cross travel limits.
The wire rope hoist features include a special heavy duty rope guide, specifically designed to counteract side pull, fail safe bottom block operated hoist limit, slack rope detection and electronic overload protection, whilst the crab is fitted with anti-derailment protection. All motors incorporate IP55 rated enclosures to eliminate the ingress of dust in the arduous environment. Radio remote control is also available for use during maintenance.
Clearpower CEO, John Heffernan, says the automatic nature of the crane system offers several advantages over alternative materials handling equipment, not least 24 hour unmanned and uninterrupted operation.
He added: “Demag Cranes has engineered the most appropriate and competitively priced solution for this application. The crane system has also helped us overcome the difficulties associated with the limited space available for the development of the CCHP facility.”
BOX OUTS FOR MATERIAL HANDLERS, WHEELED LOADERS AND CRANES
BOX OUT PICTURE STORY
As part of JPE’s expansion plans, the recycler of aggregates, clays and soils has bought Doosan DL450 (pictured) and DL420 wheel loaders and Doosan DX225LC and DX380LC crawler excavators from dealer Murley Construction. Wolverhampton based JPE has been involved in high profile projects in the Midlands area, including the Black Country Route, Trent Valley Four Tracking Project (TV4), the M6 Toll Road and the M6 hard shoulder strengthening.
The DL420 wheel loader is being used for loading work at the JPE operation at Tamworth in Warwickshire, at its washing plant. The facility produces fully washed recycled aggregates including sand and 40, 20 and 10 mm gravels from fully sustainable sources.
The Doosan DL450 wheel loaders are being used for general material handling in the stockyards and lorry loading areas at the company’s Midlands locations. The Doosan DX225LC and DX380LC crawler excavators are being used for recycling work on a major earthmoving project in the area. The latter weighs in at 37.9 tonnes and has a digging force over the bucket of 21.7 tonnes, while over the arm is 17.3 tonnes. Using the power boost increases both forces by 5% and the high engine power and high swing torque (12,000 kgf.m) means it can work efficiently on slopes.

Plant hire firm Fork Rent has just ordered 600 JCB Loadall telescopic handlers as part of its expansion programme from dealer Watling JCB. This brings the total number of JCB machine purchases over the last 24 months past the 4,000 mark and £40m in investment.Managing Director Guy Nicholls says: “The latest investment means that by April 2012 all machines in Fork Rent’s fleet will be less than 24 months old, providing customers with reliability and peace of mind.”
Fork Rent invests in JCB telescopic handlers from 515-40 to 515-170, which includes the HiViz models with air conditioning, sway control for chassis levelling, turbo engines and hydraulic side shift forks. Fork Rent has the most recent JCB LiveLink and keypad immobilisers fitted whenever possible.
Customers can now specify SG Revolution super cushion solid tyres from International Tyre and Wheel Solutions (ITWS) on the just launched JCB 550-80 Loadall.
It is JCBs largest telescopic handler and its engineers ran a series of exhaustive tests to check the specification of the tyres before selecting SG Revolution as an approved supplier. The tyres eliminate the risk of puncture and are ideal for tough working environments such as waste and demolition. SG Revolution also offers a Service Exchange scheme where they will renew a customer’s set of tyres in just a few hours to minimise downtime.
