Material lifting products cover a broad spectrum of both heavy-duty and light-duty mechanical lifting and loading equipment and accessories.

14 Jul 2020 In bridge design and evaluation, traffic load spectrum is very important. Portable scales are reliable, but each axle load has to be measured.

If the axle load is at support, we should calculate the distribution factor for shear assuming the deck is simply supported by the stringers. This procedure is called “Level Rule” Level Rule should only be applied to the axle load at the support. The normal live load distribution factor … The Ministry of Road Transport & Highways has issued a notification increasing permissible truck axle load. As per the amended rules, the maximum safe axle weight of each axle type in relation to the transport vehicles (other than motor cabs), with regard to … Axle Haulage, Dunstable. 409 likes · 2 talking about this.

Heavy trucks and buses are responsible for a majority of pavement damage. 2018-11-01 2005-06-14 Based on the analysis of load spectrum data, the loading sequence and the interaction between loads are considered, a fatigue life prediction model based on load spectrum is proposed. The load spec of the axle loads are considered below.

The model is demonstrated by investigating the influence of axle load, vehicle speed and wheel profile on generated impact noise levels.

The contribution presented deals with the effect of Standard Load Equivalencies Type of Axle or Axle Group Loading Equivalent to One ESAL (kips) single tire single axle 12 dual tire axle 18 tandem axle group 32 tridem axle group 48 4 or more axle group 48 An axle is considered part of an axle group when it is less than 8 feet from another axle or group. 2009-08-03 Variations in the dynamic tire forces of commercial freight vehicles, known to accelerate the road damage, are strongly related to vibration modes of the vehicle associated with vertical and pitch motions of the sprung and unsprung masses.

The load spectrum is preprocessed and the probability density function of mean and amplitude are fitted. The running condition of the train is analyzed, the one-dimensional program load spectrum of wheel and axle load is constructed by extrapolating the load spectrum. According to the modified fatigue cumulative damage method, the fatigue life about front axle wheel at ground considering fig. (1), we get, Mr × L = Mt Cos θ × Lf Œ Mt Sin θ × H (1) The above equation gives the weight on the rear axle on grades, through which increase in weight (∆ Mg) on the rear axle due to grade can be calculated.

The high levels of tire induced road damage caused by heavy vehicles has prompted a growing demand for the design of road-friendly vehicles.

Results show that the axle load spectrum is basically same in the same direction and very different in the different directions on the Jinghu expressway, and axle load distribution of each day is similar to the one of a year. It studies the distribution of overload rate and overload weight for all kinds of axle-wheel types.

The load spectrum can provide reference for fatigue life test and life prediction of loader drive axle. In order to study the preparation method of gear fatigue load spectrum for loaders, the load signal of four typical working conditions of loader is collected.

This characteristic affected the accuracy and computational performance of the pavement analysis.
