for vertical adjustment.
•
Attached to brackets bolted to Tru Beams.

17. Internal form hanging bracket
• Adjustable form support bracket head
and clamp plates bolted into wall
support frame.
• Facilitates the connection to the
overhead primary beam.

18. Internal Corners
• Rigid, flexible and strippable corners
(depending on core profile).
• Where possible, flexible corners used in
conjunction with corner pins.
• Eliminates need to dismantle forms.

19. Wall Bracket Assembly
• Brackets bolted into inserts cast in
previous pour.
• Connected to wall support frame,
supporting formwork once in lifted
position.
• Finite adjustment for levelling using
Threaded Bar (if required).

20. Jack Bracket
• Supports and houses hydraulic cylinder.
• Bolted into inserts cast in previous pour.
• Supports the formwork system during
lifting sequence.
• Remain fixed to hydraulic cylinder
during retraction and relocation.

21. Walkway Bracket
• Bolted to overhead beam system.
• Hanging below the bottom of the
formwork system.
• Facilitates retracting of forms, steel
reinforcement fixing and cleaning of
forms.
• Designed to be used in conjunction with
timber beams and plywood.
• Creating a level and hazard free working
platform.

22. Internal Trailing Platform
• Supported from overhead steel beams.
• Provide safe access for operatives.

34. Shutter assembly
Pre-assembly of many components greatly reduces the
set up time onsite and can be started well in advance of
the site being ready to install the formwork.

35. Shutter assembly
Pre-assembly of the formwork is carried out using fabrication jigs and
can also be done well in advance of the actual site set up (on or off
site).

36. Shutter assembly
In some cases, by prior arrangement, the fabrication of the formwork panels can be
assembled off site, then transported to site fully assembled and ready to install. This
can save space on congested work sites.

37. Shutter assembly
Larger panels that are too big to be transported by road can be assembled
on site.

38. Set Up
The formwork panels are then prepared and oiled prior to lifting into
position.

39. Set Up
The Internal Rigid Boxes are installed first and fixes the internal
shape/dimensions of the core – this is a unique feature of the
Tru-lift Self Climbing Formwork System.

40. Set Up
The Steel Walers are easily spliced to any length enabling very large panels
such as this 4.2m high x 20m long panel to be fabricated and lifted into
position in one piece.

41. Set Up

42. Set Up

43. Set Up
On completion of the rebar and formwork installation the steel grid
beams are positioned.

44. Set Up

45. Set Up
Bolts and Grid Plates are used for the connections between the grid beams, the
Formwork and Hydraulics.

46. Set Up
Top Decking and Edge Protection are added upon completion of the Grid
Beam placement.

47. Operation
The Tru-lift Self Climbing System is operated from a central control
room. Each of the Hydraulic Rams can be controlled individually or
collectively with the flick of one switch.

48. Operation
The Tru-lift Self Climbing System is generally mounted to the walls of
the first pour. However if the customer would prefer, it can be designed
to form the first pour and push off the base slab as was done on this
particular project.

49. Operation
The Tru-lift Self Climbing System is truly unique in that the whole system is
jacked in one Jack stroke, eliminating the need for resetting the hydraulics
throughout the lift saving a great deal of time. On this particular project the 3.8m
typical floor height was easily accommodated by jack stoke and capacity.

50. Operation
The Tru-lift Self Climbing System is to be used to form the first
pour. The Hydraulic Rams should be prevented from movement by
setting brackets around the bottom of it into the base slab.

51. Operation
External Hanging access brackets are
added on the initial lifts until the
desired length is achieved.

52. Operation
Suspended access
scaffolds can also be
accommodated as seen
here from below.

53. Operation

54. Operation
Rebar cages can be prefabricated and craned into position to speed up the
cycle times if desired.

55. Operation
When the setup is complete the Tru-lift self climbing system is
operated completely independently, without the need for a crane
to handle the Formwork and easily out performs traditional
Jump form systems.

56. Operation
The contractor using the Tru-lift System on this particular project was able to
achieve a pour cycle of just 48 hours with 1,100m2 of formwork being jacked in
20-30 minutes.

57. Dismantle
Upon completion of the structure the system is dismantled in the reverse order to
that of the erection.
The Hanging access
platforms are
removed first.

58. Dismantle
Followed by the external formwork.

59. Dismantle
Next the top decking is systematically removed.

60. Dismantle

61. Dismantle
The final step is the removal of the internal formwork and wall brackets.

62. Methods
Detailed method statements are
provided for assembly, erection,
running and dismantle of the
system.
Site supervision is provided at all
stages of the contract.
