  15. 15. Inner Corner Assembly Corner pin used to strike internal forms: • Drives through offset holes and reversed for ‘reset’.
  16. 16. Trolley • Designed to roll along lower flange of overhead beam. • Supports the external form using threaded rod for vertical adjustment. • Attached to brackets bolted to Tru Beams.
  17. 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. 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. 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. 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. 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. 22. Internal Trailing Platform • Supported from overhead steel beams. • Provide safe access for operatives.

  34. 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. 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. 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. 37. Shutter assembly Larger panels that are too big to be transported by road can be assembled on site.
  38. 38. Set Up The formwork panels are then prepared and oiled prior to lifting into position.
  39. 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. 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. 41. Set Up
  42. 42. Set Up
  43. 43. Set Up On completion of the rebar and formwork installation the steel grid beams are positioned.
  44. 44. Set Up
  45. 45. Set Up Bolts and Grid Plates are used for the connections between the grid beams, the Formwork and Hydraulics.
  46. 46. Set Up Top Decking and Edge Protection are added upon completion of the Grid Beam placement.
  47. 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. 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. 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. 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. 51. Operation External Hanging access brackets are added on the initial lifts until the desired length is achieved.
  52. 52. Operation Suspended access scaffolds can also be accommodated as seen here from below.
  53. 53. Operation
  54. 54. Operation Rebar cages can be prefabricated and craned into position to speed up the cycle times if desired.
  55. 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. 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. 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. 58. Dismantle Followed by the external formwork.
  59. 59. Dismantle Next the top decking is systematically removed.
