What's New at Bauma 2016

Doka Formwork Developments

Doka Formwork Developments

Under the tag line, “Forming even faster”, Doka introduced several new formwork systems at Bauma 2016.

Amidst an array of new equipment, some specifically for Asia , Doka displayed the new Framax Xlife plus framed formwork. This system features a revolutionary form-tie technology that can be operated from one side and has no wearing parts.

All panels are equipped with the existing characteristics of Framax Xlife. At 1.35 m, their form-tie grid is wider. Compared to a 1.20-m form-tie grid, this means up to twelve percent cost-savings on form-tie points and form-tie hole finishing work.

Form-ties are quickly ready to use when ‘parked’ directly at the form-tie point. This system yields up to one third in time savings during forming and stripping. The panels consist of completely hot-dip galvanized frames and robust Xlife sheets.

Another introduction was Dokadek 30 - a beam-less, hand-set formwork system designed as a lightweight steel construction faced with a wood/plastic-composite sheet.

The system combines the advantages of a panel floor formwork system with those of Dokaflex floor formwork. Its 3 m² panels make it fast in typical zones, yet, because it is easily combined with Dokaflex, it is also quick and flexible in the infill zones.

World’s tallest multipoint Jack-Up SystemWorld’s tallest multipoint Jack-Up System

Enerpac has been awarded a contract by the leading engineered heavy lifting, rigging, and transport company, Burkhalter, to extend the height of Enerpac’s 2000 metric jack-up system from 20 m to 36 m for future projects.

The near doubling in height will produce the world’s tallest jack-up system, allowing Burkhalter to handle more civil engineering and industrial multipoint lifts.

Enerpac’s jack-up system is a custom developed multipoint lifting system. A typical system setup includes four jack-up towers positioned under each corner of a load. The four tower setup has a lifting capacity of 2,000 metric tons.

The lifting frame of each jack up tower contains four hydraulic cylinders in each corner which lift and stack steel boxes measuring 1 m in height. A load is lifted in increments as boxes are inserted via an automated system, lifted, and stacked; forming ‘lifting towers’.

We had considered using strand jacks for a bridge demolition project, however, the barge-mounted Enerpac jack-up system will be a safer more efficient, synchronised lift of the bridge off its foundations,

said David James, project manager at Burkhalter.

Working with the Enerpac team, we developed the concept of a taller jack-up system that retained the lift capacity and versatility of multipoint synchronised lifting for loads up to 2,000 metric tons.

Increasing the height of the system will involve adding an additional 56 boxes and four strengthened corner bracing units to accommodate the extra 14 boxes per corner. The jack up system is controlled by a central computer control unit. Each tower’s lifting and lowering operations occur simultaneously; the computer control unit’s synchronous technology maintains the balance of the load.
