DLT jacking systems and engineering have been used in the construction of many major building
structures, using modular construction and heavy lifting techniques for early completion.
Maximizing offsite pre-assembly allows the foundations to be installed
in parallel with the structure and many elements of the structure to be
assembled offsite at the same time. The equipment and techniques of transporting and
erecting large/heavy sub assemblies are key to the success of these projects.
Examples of where our equipment and expertise has been used on building projects are as follows ..
<< Calvary Church Convention Centre, Kuala Lumpur, Malaysia
DLT were awarded two contracts from Victor Buyck (Malaysia) on this project. The first was to supply a 4 x DL-S185 strand jack system to lift 2 No 200 tonne 60 m long mega trusses that are used to support the roof over the main hall of the convention centre.More >
The second was for the design and supply of a synchronised jacking system to open and close 2 No 270 tonne ‘angel’ wings located on the roof . More>
Brasilia Stadium cable net roof erection, Brazil >>
DLT supplied a 48 x 98 tonne computer controlled strand jack system to Protende in Brazil for the erection of a cable net roof structure on the Brasilia stadium, constructed to host the 2014 world cup. More >
DLT were sub-contractors for the erection of the 940 tonne steel roof structure for the new 2000 seat theatre as part of ‘The Venetian’ Development in Macau. Our scope included erection engineering, equipment rental and site operation. The roof trusses were assembled on site at ground level and then lifted into position using a climbing jack system. The roof trusses were erected in 3 separate lifts, each weighing up to 400 tonne. More>
Haeco Hangar 3A roof lift, Hong Kong >>
DLT were sub-contractors to China State-Leighton JV for
the lifting of the 3,520 tonne pre-assembled steel roof. The roof was lifted
30m using 8 No DL-S418 strand jacks mounted on 4 No 40m high DL-TS3000 free
standing towers and 6 No DL-S185 strand jacks mounted on the permanent concrete
columns. All jacks were monitored, synchronised and controlled by a single
operator using our DL-P40 computer control system
DLT were responsible for the detailed erection engineering for the 18,500 tonne steel roof structure of the new main core terminal building, and for a 1000 tonne air traffic control tower. Both were fabricated off-site and erected on-site using strand jack lifting systems. The roof box girders, purlins and cladding to the core terminal building roof was erected in 6 No 2,000 tonne lifts. The control tower was pre-assembled off-site into 7 fully complete modules and then assembled on-site using a unique vertical jacking technique. More>
DLT were responsible for the detailed erection engineering for the 26,000 tonnes of structural steel, including stands, cable suspended roof and main arch structures. The 1,490 tonne main arch was assembled flat and rolled up into position using strand jacks. We were responsible for engineering and supervising this operation. More>
DLT were responsible for erection engineering, heavy lifting equipment supply & operation for the erection of an 8000 tonne prefabricated roof structure and a 5,500 tonne link bridge. The roof structure was fabricated and assembled in the Philippines into modules weighing up to 460 tonnes each, which were then shipped to the site for lifting and skidding into final position. The link bridge was erected piece small by a stiff leg derrick mounted on a purpose made skid track. Access to this part of the site was very restricted, requiring the stiff leg derrick to construct its own skid track and then work backwards along the skid track to erect the permanent works. More>
DLT were responsible for the design, supply and operation of a strand jack lifting system together with associated erection engineering to lift 2 No pre-assembled roof sections, each weighing over 1000 tonnes. Each section of roof was lifted with 9 No DL-S185 strand jacks. Temporary works for the lift comprised 3 No 300 tonne capacity jacking towers, plan bracing to stabilise the roof and a guide track against the concrete core structure. More>
DLT were responsible for the detailed erection engineering for the lifting by strand jacks of an 800 tonne roof truss for this aircraft maintenance hangar at Heathrow Airport. The roof structure was assembled at ground level and then lifted using strand jacks mounted on the top of the permanent columns, which were stabilised by rented proprietary towers that were anchored down to the permanent foundations
DLT were responsible for the design, supply and operation of a strand jack heavy lifting & horizontal skidding system for the erection of two 1100 tonne pre-assembled link bridges in Hong Kong for main contractor, Gammon-Skanska.
The roof to this convention centre is constructed from a complex series of curved V shaped steel trusses that work with a plan tie system in the finished state to provide a rigid and stable structure. To reduce the roof erection cost and programme, the roof was assembled in fully clad panels adjacent to the site and erected onto temporary supports within the building. We were responsible for the detailed erection engineering of the roof, including all temporary supports and stability bracing, which was required to withstand cyclone wind loads at any erection stage
DLT were responsible for detailed connection design and erection engineering of the 6,600 tonnes of steel frame to this 16 storey office block. This included heavy lifting of a 650 tonne module which was built on a lower floor and then raised 30m to the 16th floor. DLT were also responsible for supply and operation of the strand jack system to carry out this lift, using 4 No DL-S185 strand jacks.
