[15] Some smaller bridges have a weight limit (or gross weight load rating) indicated by a posted sign (hence the reference to a "posted bridge"). These are necessary when the weight limit of the bridge is lower than the federal or state gross weight limit for trucks.
The factor can be as high as 10:1 or 10 to 1, if the equipment poses a risk to a person's life. Working Load Limit ( WLL ) is the maximum working load designed by the manufacturer. This load represents a force that is much less than that required to make the lifting equipment fail or yield.
Lifting equipment can be assigned a Working Load Limit (WLL) in the interests of avoiding failure; Working Load Limit is calculated by dividing the Minimum Breaking Load of the equipment by a safety factor. [5] WLL as a concept is not restricted to lifting, being also relevant for mooring ropes. [6]
The Military Load Classification (MLC) is a system of standards used by NATO to classify the safe amount of load a surface can withstand. Load-carrying capacity is shown in whole numbers for vehicles, bridges, roads, and routes. Vehicles are classified by weight, type, and effect on routes.
A portable truck scale will have lower frame work that can be placed on non-typical surfaces such as dirt. These scales retain the same level of accuracy as a pit-type scale, with accuracy of up to + or - 1%. The first portable truck scale record in the US was units operated by the Weight Patrol of the Los Angeles Motor Patrol in 1929. Four ...
A crane's rated load is its Safe Working Load (SWL) and the design load (DL) is, (p 90) [1] = The dynamic lift factor for offshore cranes in the range 10 kN < SWL ≤ 2500 kN is not less than =.(p 84) [1] Thus for a crane with a SWL of 2000 kN (~200 tonne) its design load is not less than, = = The minimum breaking load (MBL) for the combined capacity of reeves of a steel wire hoisting rope ...
The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
When evaluating the series of tests, it was found that there is a connection between the thickness of the pavement, the number of load transfers and the axle load, and that these have a direct effect on the service life and condition of a road. The service life of the road is thereby reduced with approximately the fourth power of the axle load. [1]
