The most complex portion of this type is the arrangement of levers underneath the weighbridge since the response of the scale must be independent of the distribution of the load. [6] Modern devices use multiple load cells that connect to an electronic equipment to totalize the sensor inputs. In either type of semi-permanent scale the weight ...
Weigh-in-motion is a technology that can be used for various private and public purposes (i.e. applications) related to the weights and axle loads of road and rail vehicles. WIM systems are installed on the road or rail track or on a vehicle and measure, store and provide data from the traffic flow and/or the specific vehicle.
This review's abstract notes that newer on-board scale systems included calibration data in the load sensors, which would function as part of an on-truck computer network. [13] Thus, a calibrated load sensor on a trailer or semi-trailer could be attached to any tractor that could receive the trailer sensor's weight transmission over the network.
Every load cell is subject to "ringing" when subjected to abrupt load changes. This stems from the spring-like behavior of load cells. In order to measure the loads, they have to deform. As such, a load cell of finite stiffness must have spring-like behavior, exhibiting vibrations at its natural frequency. An oscillating data pattern can be the ...
Two types of loads may result in overweight trucks: divisible and non-divisible. A divisible load is a load which can be easily divided into smaller parts, such as products that are shipped on pallets, automobiles or grains. A non-divisible load is a load which is unable to be divided into smaller parts, like a piece of equipment or a steel beam.
The Palletized Load System (PLS) is a truck-based logistics system that entered service in the United States Army in 1993. It performs long and short distance freight transport , unit resupply, and other missions in the tactical environment to support modernized and highly mobile combat units.

On a turret truck, the forks rotate during stacking, eliminating the need for the truck itself to turn in narrow aisles. An order picker allows the operator to be lifted with the load to allow for less-than-pallet-load picking. Automated guided vehicles (AGVs) are industrial trucks that can transport loads without requiring a human operator.
