Handle only from top surface or with lifting gear. Hand trap - ever put hands in cores or between slabs.On slabs less than 4 feet wide, use belts or chokers do not use clamps.If this cannot be accomplished, then belts or chokers should be used instead of clamps. The slab shall be lifted with lines vertical. Clamps should be used only with spreader bar.Never turn slabs on edge or upside-down with minimum safety factor 5:1.Never hoist slabs by hooking into cores.For Hoisting: - Use lifting devices (clamps, belts, chokers, forks) of adequate capacity.never use Hollow core as a platform for hoisting people or materials.Always use safety slings when hoisting with clamps or forks.
Refer to shop barcode sticker / drawing for slab weight.Blocking for stockpile, same location as lifting.Minimum end bearing is 75mm unless specified otherwise on shop drawings.Hollow core slabs are to be located and installed in accordance with Approved Shop drawings.
When using clamps, ensure that the clamp edges fit properly against sound concrete grooves insides of slab, after crane has taken load but before hoisting. Keep the dunnage accurately aligned from slab to slabīalance load to avoid slipping and to eliminate twist on clamps or belts
Anchoring to hollow core plank full#
Separate the slab with full width 2” X 4” dunnage. Stockpiling at the site may be necessary - use full width 4” X 4” dunnage placed on stable level ground. Prior to unloading, the installer should inspect each shipment.Īny damage not specifically reported on delivery slips and/or not reported to the project engineer becomes the responsibility of the installer. Irregular slabs are placed on top of the load. Off-loading sequence may differ slightly from the shipping list due to the slab geometry.
