Riverside Contracting, Inc. hauls equipment, asphalt oils, asphalt and gravel on the highway of the United States and Canada. In doing so, it is the policy of Riverside Contracting Inc. that all drivers that are hauling these commodities follow all the rules and regulations of the Federal Motor Carriers Safety Administration. The following policy applies to the all employees who move equipment and materials on US and Canadian highways.
Transporting Equipment:
Chains Size |
Working Load Limit |
3/8 inch |
6600 pounds |
1/2 inch |
11,300 pounds |
Example 1: A machine weighs 68,000 pounds, four ½ chains are required to secure the load.
ü Example 2: A machine weighs 40,000 pounds, four 3/8 chains are required to secure the load.
When chaining down a piece of equipment there are 2 different methods of chaining it to the lowboy, a Direct Pull” or an “Indirect Pull”.
Direct Pull: This is when the chain is hooked to the lowboy with one end of the chain and the other end of the chain is hooked to the piece of equipment. The boomer is hooked in the middle of the chain and the slack of the chain is taken up so the machine will not move. This method of chaining down the piece of equipment will reduce the tensile strength of the chain by 50%. Example: if you have 4, 3/8 chains on a piece of equipment to tie it down and the tensile strength is 6600 pounds per chain, for a total of 26,400 pounds, the tensile strength will be reduce by 50% for a tensile strength of 13,200 pounds. This will not be enough tensile strength for most loads.
Indirect Pull: This is when the chain is looped through an eye on the lowboy and an eye on the machine. The boomer is then hook on both ends of the chain taking up the slack in the chain so the piece of equipment will not move. By chaining down a piece of equipment this way there is no reduction in the tensile strength of the chains.
If possible always tie down your load using the “Indirect Pull” method. If you cannot tie the equipment down using this method you need to add more chins to the load to make up for the loss of tensile strength.
Flatbeds & Misc Loads:
Example: if an item is 33 feet long it would require 5 tie downs. Two tie downs for the first 10 feet, one tie down for each additional 10 feet and one for the last 3 feet.
Gravel, Bituminous Material and Dirt:
Tanks:
