Horizontal concrete panels can be installed using a telehandler or similar machine. ACP (Concrete) Ltd supply a set of tested lifters for safe handling of the panels which should be used in conjunction with chains or a spreader beam (tested to the appropriate weight).
1) When off loading with a telehandler the forks should be at widest position and care should be taken to avoid damage to the panel edge whilst positioning the forks underneath. Unit weight may be calculated by multiplying the unit length, width and depth in metres and multiplying this figure by 2.45 (tonnes per cubic metre of concrete). For example 6.085m x 1.2m x 0.145m x 2.45 = 2.59t
2) Once off loaded the panels should be stacked no more than 6 nos high on flat, firm ground. Timbers should be aligned vertically to prevent panels bowing or cracking at fifth points from each end.
3) Lifting clutches should be attached to lifting inserts in the top edge of the panel and linked by lifting chains (supplied by others and tested to the correct weight). Alternatively 'D' shackles should be fixed through holes cast into the top side of the panel.
4) The angle of the chain should not be greater than 60º from the vertical. The panel can then be lifted slowly into the vertical position and carried to the bay for fixing. When lifting from the stack it is important to be aware that the lifting insert is designed to work at 0-90º from the horizontal and under no circumstances may load be applied to the lifter outside of these angles, (see PDF.file)
5) Panels are fixed to the stanchions using the plates and bolts provided, over tightening can cause the socket to rotate and lead to spalling of the concrete. It is advisable to place a small amount of mastic between the plate and the stanchion to prevent the plate moving over time. Once the panel is secure the lifters can be released.
