Wessex Demolition Choose Lehnhoff!
Added by +WorsleyPlantCoUk
After a visit to the Lehnhoff factory in Germany, Wessex Demoliiton chose to invest and are now delighted to be enjoying the benefits. One of their first projects with the new system involved the demolition of a former college in Slough to make way for a new development of much needed housing stock.
The two storey steel framed building dated back from the 1970s and consisted of teaching and canteen facilities. The building was vacated with many of the fixtures and fittings remaining inside with the Wessex team having to sort and recycle as much as possible before any structural demolition could take place.
Wessex pride themselves on operating the very latest technology available to demolition professionals and have recently been undertaking tests with the two main suppliers of hydraulic couplers specifically designed for the rigours of the demolition industry.
After testing both makes of coupler for an extended amount of time, the company plumped for the Lehnhoff Variolock system supplied by Middlewich based Worsley Plant. The Slough site was home to a pair of excavators sporting the Lehnhoff system including one of the company’s latest Volvo EC250EL excavators and the first machine to have the system fitted, a Doosan DX300LC. Site Manager for the project, Paul Beaumont explained that the Doosan fitted with the Lehnhoff system has been on site for a few days and has made an instant impact on the speed at which the project has moved forward. “The tried and tested system is very good. We are always using the correct tools for the job now, no more making do. We must save at least half a day per week with not having to use the older, non hydraulic couplers.”
The heavy duty design of the unit has impressed Wessex Demolition’s Contracts Manager) Ashley Grant. “One of the benefits is the metric to metric couplings on the unit, there is no downsizing to imperial dimensions meaning the flow of hydraulic oil is always at its optimum levels. The build quality is second to none with a pair of integrated lifting hooks on the unit meaning we are able to undertake any lifting duties safely.
To meet current guidelines on quick hitch safety, the Lehnhoff units have a bright green indicator pin fitted above the front jaws allowing the operator to have a visual indication of whether the attachment is secure or not. To provide a positive and rattle free connection the rear locking pins have a tapered top edge allowing a tight grip to the attachment and are always under pressure to ensure the attachment stays connected at all times. The VL250 units supplied to Wessex are fitted with five valve ports to allow a wide variety of attachments to be utilised. Two – 25mm, two – 12mm and a single 20mm port are all positively connected to the valve block situated on the attachment and allow a leak free and reliable connection at all times. The larger ports allow the oil to flow at a lower temperature giving Wessex greater fuel savings over other hitches. The lack of trailing hoses is another plus point for Wessex in purchasing the Lehnhoff system. Both the cost in repair and downtime will be massively reduced with the new system but also the environmental benefit of not having leaking fittings or burst hoses will help the company
Both units were being put to good use swapping quickly from bucket, to hammer, to sorting grab. Another benefit of the Lehnhoff system is the large scope for compatibility across weight ranges. The units supplied to Wessex are capable of using attachments normally run on 20 to 40 tonne excavators which means that a smaller fleet of attachments are now needed, resulting in lower purchasing costs. Worsley Plant has also supplied a new Rotar selector grab for the excavators and this has also come in for praise thanks to its build quality and speed of operation.
The way in which the Lehnhoff system has altered the operational methods is clear to see with the operator now very quickly changing tools over to allow material to be moved, broken and sorted in a far more effective and productive manner.
