Cargo Carrying Units (CCU’s) Design While it is acceptable to use wire mesh / expamet on the sides of a basket, it should not be used as floor material. Can you give three reasons why it is not suitable? floor design : bad Expament / wire mesh / open grating are NOT suitable as floor material! mesh sides with SOLID floor cargo basket : good Answer : 1. expamet is generally not strong enough 2. it is easily pierced by sharp heavy objects 3. the possibility of smaller items falling through the mesh, i.e. dropped objects 9

The following information is based on that guidance and industry good practice. Padeyes that have been flame cut must have all cutting marks ground out to eliminate stress points. The holes should always be drilled or bored and not flame cut. If cheek plates are fitted, they should be line bored after fitting. smooth profile, hole correct size, hole bored / drilled, adequate thickness. adequate material left around hole, good quality welding padeye : good flame-cut outer profile, flame-cut hole, hole too near top of padeye, padeye plate inadequate thickness padeye : bad 16

Positioning of Loads on Trucks When loading trucks, for standard or normal cargo, place the items on the truck in the reverse order of removal, i.e. first off, should be the last on. The first items loaded should be placed hard against the headboard of the trailer, so that in the event of heavy braking, they cannot slide forward gaining momentum. This is particularly important when loading bundles of tubulars, which can turn into missiles under heavy breaking. cargo hard against trailer headboard cargo hard against trailer headboard : good When transporting tubulars, when each bundle is landed, the slings should be laid along the length of the bundle to prevent them being crushed by the next bundle. Where possible, position the slings where they can be reached from ground level, but ensure they cannot fall and drag along the ground (lash with soft rope where necessary). This makes it easier for offloading at the supplier’s yard. Samson posts (stanchions or bolsters) should be in place along the sides of the trailer and wedges should be used where necessary to stabilise the load. no trailer headboard : bad WARNING : never use a trailer that doesn’t have a robust headboard. wooden headboards are acceptable, but steel or steel covered headboards are preferred 73
