The climbing system CB150 is a basic system that economical service on crane-lifted climbing projects.Crane-operated formwork for vertical concrete members;  Safe working conditions provided by fully railed-in 1.50 m wide working platform.  Safe up-and-down access between platforms provided by integrated ladder system.   Small number of suspension points, thanks to the brackets’ high load-bearing capacity.   Less crane-time needed, as the climbing scaffold and formwork are moved up as a single unit   Simple adjustment options for precise horizontal and vertical alignment of the formwork.


LEJANT A= The Climbing bracket 150is used for set up the working platform, and carries the formwork element or panel.    B= Vertical waler for fixing the formwork elements/panels. The waler connector are used for fixing the ver-cal waler with formwork.    C= Push-pull Propit’s function for aligning and repositioning the formwork elements or panels.    D= Suspended Working Platform  150 cm wide suspended platform for bolting onto the climbing bracket. Suitable up to heights of 3.85 m.    E= Waler Connector  Fixes the formwork element or panel to the vertical valer    F= Tension Belt Secures the climbing unit against wind loads. Continuous length adjustment up to 6.00 m.


Preparing the positioning point

Do not place concrete directly above the conical an-chors. Do not allow the vibrator to touch the anchors. These measures prevent the anchors working loose during pouring and vibration. The axis of the conical anchor must be at right-angles to the surface of the concrete – maximum angle of deviation 2°. Tolerance for locating the positioning points and suspension points: ±10 mm in the horizontal and the vertical. If wind speeds > 72 km/h are likely, and when work finishes for the day or before prolonged work-breaks,always take extra precautions to fix the formwork in place. a >10cm, b= depth of concrete cover on the conical anchor side: 2 cm (in the case of minimum wall thickness)The short conical anchor has a considerably lower de-sign capacity than other conical anchors type. For this reason, the short conical anchor is only allowed to be used on systems with low tensile loads at the anchoring location, such as on climbing systems inside shafts.  If the geometry makes this impossible, a revised static calculation, with extra reinforcement steel, must be produced.  The short  conical anchor is thus only permitted for wall thicknesses < 24 cm. Note: Where climbing formwork is used on both sides, the conical anchors must be located at an offset to oneanother, as necessitated by the thickness of the wall.


Instructions for safe transportation of the entire unit

Before lifting remove any loose items from the form-work and platforms, or secure them firml.   “Passenger transportation” is forbidden!   Observe all regulations applying to the operation of cranes where higher wind speeds are experienced.   Angle of inclination ß : max. 30°   When using lifting bracket, ensure that these have suf-ficient load-bearing capacity! Any lifting brackets on the Alpiflex 50 formwork el-ments, or Alpimax lifting hooks, must not be used for lifting the unit as a whole. Attach the lifting chain to the lifting brackets of the vertical valer. Warning; When one climbing unit is lifted and repositioned, this opens up exposed fall-hazard locations on the remaining units. These exposed locations must be made safe by put-ting up an access prohibition barrier.    The personel in charge of the repositioning operation are responsible for positioning the access prohibition barriers correctly.  During the lifting/repositioning cycle, no site personnel are allowed to be on the units to be climbed or on adjacent units for repositioning.    Person operating the climbing formwork must use per-sonal protective equipment during the lifting operation.


Phase 1

Assemble one side of the formwork. (Alpiflex50 Alpimax) Mount the positioning-points. Place the reinforcement. Close the formwork and tie it. Pour the concrete for 1st section. A=Conical anchorepoint for repositioning and tension belt Disassemble the formwork.  Clean the formwork.  Set the gang-form down on a flat surface with the form-plyfacing downwards.  Prepare the formwork for the climbing operation.

Phase 2

Hanging the working platform into place on the conical anchore points: Prepare the conical anchore points.  Raise the prepared working platform with the lifting chain and hook it into the conical anchore points. TensionBelt (ifnecessary):  Attach a tension belt to the climbing bracket . Fasten the tension belt to the conical anchor prepared before. A=Tension belt B=Tension belt connector C=Conical anchor

Phase 3

Formwork: Attach the lifting chain to the lifting brackets on the pre-assembled formwork.  Transfer the formwork to the working platform by crane. Fix the vertical valer with adjusting unit to climbing bracket.  Fix the pre-assembled formwork to the vertical waler with waler connector.

Phase 4

Insert handrail boards and use nails to secure them to theguardrail post. Formwork set-up and pouring Set up one side of the formwork.  Assemble the conical anchor.  Place the reinforcement.  Close the formwork and tie each other.  Pour the concrete 2nd elevation. Disassemble the formwork.  Clean the formwork.  ! Make it impossible to use any of the forbidden attachment methods when lifting and repositioning the unit in one piece.

Phase 5

Prepare the conical anchor points.  Disassemble the tension belt. Attach the lifting chain to the lifting brackets of the vertical waler.  Remove the climbing bracket unit from the conical anchore points. Climbing bracket unit is hooked into conical anchor which prepared before. Phase 4 are repeated and concrete is poured.

Phase 6

The working platform is assembled in the climbing bracket, so the anchorage materials left on the wall are easily removed.
Assembling the working platform steps:
  1. . Aligning the climbing brackets
  2. . Assembling the platform beams
  3. . Fitting the bracing
  4. . Assembling the deck-boards
  5. . Assembling the railing
  6. . Sideguards on exposed platform-ends
  7. . Assembling the Vertical waling and push-pull prop.
  8. . Assembling the formwork (Alpiflex 50 – Alpimax
  9. . Assembling the suspended platform.
