This load simulator can be offered with its own hydraulic pump or can be connected to certain play detector pump units, which in that case have an extra valve set for connecting one of the load simulator. A proportional pressure regulator valve is used for the load adjustment. The desired axle weight is controlled with the remote control unit of the roller brake tester and displayed on the readout unit. If you want to include the influence of the load sensing valve of the vehicle in the test, then fit the chains/belts to the chassis. If you don’t want to include the influence of the load sensing valve in the test, then fit the chains/belts around the axle.
The use of an axle lift without tightening down the chassis or axle
This is the fastest way for increasing the axle weight. There is no need to leave the driver seat after driving on the rollers for attaching belts or chains. From the driver seat with the remote control the weight can be increased and meanwhile read from the display or monitor. The weight can be increased until the other axles near the axle on the rollers are lifted from the ground.
The use of an axle lift including tightening down the chassis or axle
In this way the axle load can be increased until its maximum permissible weight. For each axle however the belts or chains have to be fitted. Like with the pulling cylinders the belts can be fitted to the axle or to the chassis. When fitting them to the chassis the load sensing system of the vehicle is taken into account during the brake test.
