Water Catchments Stabilisation / Gibraltar.
| The Water Catchments
on the Rock of Gibraltar required decommissioning and stabilizing. Almost 10,000 soil-nails needed installing requiring the use of a number of heavy duty impact drills and the removal of 1000,s of corrugated tin sheets originally used to catch rain water for the island. ALPS supplied the specialised Lifting & Pulling equipment required to manoeuvre the 15-Ton+ rock drills and purpose built carriages up and down the ancient 45% sloping sand-dune. |

The Millennium Dome Construction Project
| The Millennium Dome construction project required the design and installation
of a unique multi-winch lifting system in order that the central hub and
subsequent circumferential "Nets" could be raised to their installed height.
ALPS were commissioned to design and procure the system that would perform this difficult task. 36 Double reeved 6 Ton linear wire rope Jacks (SP6) were installed at the mast head and powered from a purpose designed hydraulic power pack also situated at the top of each mast. A combined pulling force of 432 Tons raised each section of the roof "Net" and enabled the Industrial Roped Access workers, also supplied by ALPS, to make the socket attachments at the node. Access to each of the mast head platforms was made easy by the design and installation of 12 powered Man riding cradles each carrying three men with their materials to the mass head platform 90 mts. off the ground, in 10 minutes. |
The Combined Capacity Of The 36 X Wire Rope "Net Lifting" Winches Was 432 Tons The "Net" installation Winching System and Suspended Access Man riding
solutions were designed and procured by ALPS.
