methods

there many different ways , materials available stabilize , secure cargo in vehicles , intermodal containers. combinations of load securing methods use. example load can blocked against headboad of truck , have webbing restraints tying down.

blocking & bracing

blocking & bracing load securement method using lumber , metal bars reduce or inhibit front rear shifting of freight/cargo. plastic forms used.

blocking , bracing timber


fasteners

depending on type of load , particular vehicle, large bolts , nails may used. these may on load or on wood blocks used brace load.

dunnage

dunnage securing cargo includes scrap wood fill voids in cargo, wooden boards forming cribs , blocking , bracing, , modern mechanical, spring-loaded post-and-socket systems, dunnage segregates cargo in hold , prevents shifting of cargo in response ship or vehicle motions.

strapping

polyester strapping , dunnage bag application

strapping used create transportable unit. types of strapping include steel, polyester, polypropylene, nylon, paper, , composites. type of strap used depends on requirements, example, strength, elasticity, ability withstand various environments, easy of use, safety, , cost.

all types of tensioned strapping, particularly steel, need handled because of potential injury.

lashing

polyester lashing application

lashing securing of cargo transportation goal of minimizing shifting. items used lashing include ropes, cables, wires, chains, strapping, , nets. these items anchored container , tensioned against cargo. form of lashing used 4 devices attached top of each corner of container. lashing products , methods governed various authorities such association of american railroads (aar) rail transportation in north america, international maritime organization (imo) ocean transportation , national motor freight traffic association (nmfta).

dunnage bags

dunnage bag application in container

whereas strapping , lashing used secure odd-shaped cargo such machinery, structures, , vehicles. dunnage bags used homogeneous shaped cargo such food & beverage products, electronics , appliances , roll paper. often, strapping/lashing , dunnage bags used in combination secure chemical products. dunnage bags not approved rail transportation of hazardous materials in united states.

dunnage bags, known air bags, introduced 40 years ago convenient, fast , cost effective alternative secure , stabilize cargo in iso sea containers, closed rail cars, trucks , (ocean-going) vessels. purpose of dunnage bags misunderstood when considered void filler prevent lateral movement of cargo. when applied however, dunnage bags form 3-dimensional bulkhead of cargo preventing both lateral , longitudinal movement.

tie downs

chains used on logging truck

heavy loads secured vehicles tie down straps, heavy duty strapping, or tensioned chains.
