Doka Formwork Developments

Under the tag line, “Forming even faster”, Doka intro-

duced 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

w e a r i n g

parts.

All panels

are equipped

with the ex-

isting char-

acteristics of

F r a m a x

their form-

tie grid is

w i d e r .

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 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 lift-

ing system. A typical system setup

includes four jack-up towers posi-

tioned 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 sys-

tem will involve adding an addi-

tional 56 boxes and four strength-

ened corner bracing units to

accommodate the extra 14 boxes

per corner.

The jack up system is con-

trolled by a central computer con-

trol unit. Each tower’s lifting and

lowering operations occur simul-

taneously; the computer control

unit’s synchronous technology

maintains the balance of the load.
