Let's talk about the loading and lashing of coil steel

The stowage of coil steel has a great impact on the safety of ships, so special attention must be paid to the loading. Mainly from: foil, stowage tight, binding several aspects to pay attention to.

Bilge strength is usually calculated by projection method. The maximum load of each row can be obtained by multiplying the width of each row of coil steel by the width of the bilge and then multiplying the strength of the bilge. For the condition of the second side selection, we can usually expand the width of the bilge to add an outer diameter of the coil steel to calculate.

The steel coil foil must be made of HARDWOOD (HARDWOOD, wood, etc.), the standard shall not be less than 5CM X 10CM X 1.5m, (how much can be done, 28 boards are confused) if necessary, can be used to pad double layers to strengthen the strength of the wood and share the bilge pressure.

Other requirements 10CM X 10CM X 1.5-2m SOFT WOOD (white pine, red pine, etc.) to frame the starboard side bulkhead or bottom tank bulkhead. Make sure there is no direct contact between the goods and the bulkhead to protect the bulkhead and dissipate pressure.

Wedge wood is used at the bottom to prevent the goods from moving during loading and unloading and to enhance the security of the goods during shipping. Under the condition of loading without side picking (holding pole) on the second floor, triangular wood on the side tank is very necessary.

Considering that the small gap between the coil and the coil center may converge to the center during loading, leading to the continuous sinking of the locking coil, pay attention to the decreasing height of the locking coil should not be more than one third of its outer diameter, otherwise, it will lose its effect. Intuitively, the lower edge of the inner diameter of the locking coil should not be lower than the highest point of the steel on both sides of the coil.
