Latest Suspended Access Project

Spinnaker Tower; Portsmouth

Spinnaker Tower is a 165M high observation feature constructed as part of the millennium dockside development at Portsmouth.

Spinnaker Tower at Night

It is a concrete slip-formed structure with a panoramic observation gallery at high level.

During construction of the tower the contractor required access to the faces of the two inclined hexagonal towers for preparation and painting works.

ALPS designed supplied installed and managed two special wrap-around access platforms to enable the work to be carried out safely and efficiently.

Each platform was raised and lowered using three powered manriding hoists and back safety devises.

Safety / Guide Rope Tension Springs

Above: Each platform is equipped with three safety and restraint wire ropes, these are tensioned at ground level using compression springs to absorb movement and rope oscillation.

Left: One of the two "half-hexagonal" suspended access platforms can be seen at high level; Each platform travels at 9M min'. Both platforms are contained to offer protection to both the on-board operatives and those working below.

CANARY WHARF PROJECT.

The contractors requirement was to gain Access to the large soffit and internal facade of the buildings opening without the need to erect a scaffolding structure from the ground up!

Using standard "Beeche" 3D modular truss frame components, ALPS designed a suspended mobile access platform that was quickly assembled and installed with minimum disruption giving maximum efficiency.

SUSPENSION JIBS PLATFORM AT MAX HEIGHT

Client: BOVIS Construction.
Problem: Gaining Access to the "Dome" for painting, gold leafing, electrical installation etc.
Solution: "ALPS" designed, installed and supervised for the duration of the works four custom "Suspended Access Platforms".
Each platform suspended from a custom pair of Jibs secured to structural steel work 50mtrs above the floor of the "Dome".
The Suspended Access Equipment (SAE) was kept by the centre for on going maintenance use within the main dome.

Petrochemical Projects

Arne Gravity Base

Taylor Woodrow Civil Engineering required a Suspended Access contactor to assist them with the construction of the 100, 000Ton Arne Gravity Base under construction in the far north of Scotland.
ALPS were chosen as they were capable of quickly designing, supplying and installing both standard and specially adapted Temporary Suspended Platform (TSP) and auxiliary materials hoists. These were used for both internal and external Access for T/W contactors working on the 80M concrete tower.

ALPLIFT
The rack and Pinion hoist had to be removed due to the necessity of concrete work in the vicinity of the man riding system. This meant removing the only efficient way to the top of the tower!
ALPS supplied their new "ALPLIFT" man and materials hoist to replace the mast climbing hoist on the 80M tower.
This twin hoist system has a speed of 18mpm with a capacity of 1000Kg.

INDUSTRIAL ROPED ACCESS.
ALPS Roped Access Technicians worked in shifts around the clock to assist with meeting the completion date when the 100, 000Ton structure would be floated into deeper water for completion. Their tasks included moving the Temporary Suspended Platform to the desired locations. Most high level snagging problems on the tower were also swiftly attended to by the ALPS Roped Access Technicians.
