Special assembly solution for supports without requiring a large crane.
3-D innovation The patented QXcrane system combines cableway
and SpiderCam technologies, resulting in a versatile 3D solution. Four towers, positioned in a rectangle with a maximum diagonal of 1000 m around the defined terrain, support the system. The operator’s basket, connected to the towers by steel ropes, enables safe navigation in all three dimensions within the designated area. Workers in the danger zone are connected to the basket via personal safety winches, granting them freedom of movement while ensuring immediate evacuation in emergencies. Additional features include: Coverage of an area with a diagonal of approximately 1000m, square or rectangular. Material transport of up to 500kg or three persons with 125kg each. Winch-controlled lowering of loads or persons at any point within the working area. Secure operation and navigation in the defined working area. Perfect fusion of ropeway and SpiderCam technologies.
Navigation in the 3-dimensional space.
QXcrane-2D System For defined work along a route in unstable terrain,
the QXcrane-2D system offers an ideal solution. Comprising two towers and an operator’s basket attached to a cable crane, the system ensures safe work and easy operation along the designated route. Workers in the danger zone are connected to the basket via personal safety winches, providing freedom of movement with the capability for immediate evacuation in emergencies. Additional features include: Coverage of a length of approximately 1000m (with a single tensioning field). Material transport of up to 2000kg or three persons with 125kg each. Winch-controlled lowering of loads or persons at any point along the defined route. Secure working along the designated route. User-friendly operation and maintenance.
Successful delivery
In a significant achievement, Collett has completed the successful delivery of two 160TE inlet valves to the Dinorwig Hydro-Power Station as part of
its essential upgrade scheme. Acting on behalf of Rhenus Project Logistics, the Collett Team’s accomplishment signifies a crucial milestone in the ongoing project aimed at extending the power station’s operational lifespan for the decades to come.
Measuring an impressive 5.3m(L) x 4.7m(W) x 3.7m(H) each, a total of six valves weighing 160Te each will be delivered to complete the comprehensive upgrade scheme. Prior to the deliveries, meticulous planning and
preparatory work were undertaken by Collett’s dedicated Project Management and Consulting departments. This involved Swept Path Analysis (SPA) reports, lashing calculations and plans, stability calculations, as well as a comprehensive test run and route studies. During the test run, a load replicating the exact size and shape of the valves was constructed to ensure the safe transportation of these crucial components. The first two inlet valves made their arrival at the Port of Penrhyn, situated East of Bangor, North Wales. Under CPA Contract Lift Conditions, both valves were expertly discharged from the vessel using an 800Te mobile crane. To ensure secure transport, each valve was meticulously lashed onto two 10-axle modular trailers. The journey from the port to the Dinorwig Power Station covered approximately 12 miles, with a travel time of 3 hours. Throughout the transport, a comprehensive support system was in place, including full police escorts and Collett’s in-house escort vehicles. The loaded trailers were accompanied by three 8×4 ballasted tractor units, two primary and one in support. Special Order BE16 Permits were obtained by Collett’s Permit Team to facilitate the smooth movement of the oversized cargo. Upon reaching the power station, the two main inlet valves were transported directly to a designated storage area and carefully lowered onto stools. Subsequently, after necessary preparations, the valves were transported into the mountain and offloaded by overhead gantry cranes. The Dinorwig hydroelectric power station, located
near Llanberis in the Snowdonia National Park, stands as the largest pumped hydroelectric storage facility in the UK. With a maximum power supply of 1728MW and a storage capacity of approximately 10GWh, the station efficiently manages water between the Marchlyn Mawr reservoir and the Llyn Peris Lake to generate power as needed.
