Load distribution

Operating the trailer

Load distribution

The cargo must be properly loaded, blocked, and secured to avoid load shifting.

CAUTION

• Improper loading, load distribution or cargo securement may damage the components of the floor assembly. • Do not use pallets with small sized footprints. Doing so may damage the floor assembly. • The sliding suspension must be placed in the rear most position during loading. • Ensure the trailer is on a firm and level ground during loading. • To prevent the trailer from moving forward during loading, chock wheels, or use dock locking devices.

NOTICE

• Before operating the trailer, check the highway’s legal load regulations. They may differ from the maximum load indicated on the VIN plate. • For proper trailer load distribution, you must comply with the following sections of Title 49 of the Department of Transportation (DOT) Federal Motor Carriers Safety Regulations (FMCSR) at the

FMCSA Official website (www.fmcsa.dot.gov). - Section 393.100 General rules for protection against shifting or falling cargo. - Section 393.102 Securement Systems - Section 393.104 Blocking and Bracing - Section 393.106 Front End Structure

Distributing weight

WARNING

Before each trip, ensure that the payload has been evenly distributed and securely fixed in the trailer’s storage compartment. Uneven distribution of payload weight creates potentially hazardous operating conditions, which may result in fatal loss of vehicle control.

The cargo must be equally distributed from the front to the rear. Refer to the following diagram for uniform load distribution.

Operating the trailer

Also, refer to the following examples of proper weight distribution on the cargo. To distribute equal weight on all rear tires on the trailer, position the load equally between sides.

CAUTION

To prevent unexpected movement of the cargo, secure the cargo against lateral load movement using securing straps.

Loading heavy concentrated loads

WARNING

Before each trip, ensure that the payload has been evenly distributed and securely fixed in the trailer’s storage compartment. Uneven distribution of payload weight creates potentially hazardous operating conditions, which may result in fatal loss of vehicle control.

When loading heavy, concentrated loads, distribute the load over the full length of the floor or place the concentrated load in the center of the trailer. Also, to distribute weight front to rear, use a skid with the appropriate length and firm materials.

CAUTION

Do not load the trailer with the payload concentrated at front. Doing so may reduce the tire mileage and bend the tractor’s axle system. Also, if you apply brakes suddenly, the trailer’s brakes may lock, resulting in flat spots on your tires and dangerous skidding.
