Another kind of Boom Truck is called a Bucket Truck. It has a bucket accessory with an expandable arm and specializes in lifting people, typically staff up in the air. Bucket Trucks are likewise referred to as Aerial Boom Trucks. They have a lifting capacity of 150 kg to 700 kg and the bucket itself can be lengthened up to 10 meters in the air.
Knuckle Boom Trucks are larger boom trucks that are outfitted with a crane on the rear section of the apparatus. If the length of the truck is expanded, the truck then becomes a Trolley Boom Truck. These kinds of trucks have a lifting capacity of ten tons to fifty tons.
One more kind of Boom Truck the Concrete Boom Truck that is a huge container on its back. These are constructed to carry expandable pipe and to carry concrete. Concrete is pumped with the pipe into a specific site. Concrete Boom Trucks are able to be extended up to 70 meters.
The fluid coupling type is the most popular type of torque converter used in car transmissions. In the 1920's there were pendulum-based torque or Constantinesco converter. There are different mechanical designs for constantly variable transmissions which can multiply torque. Like for example, the Variomatic is a version which has expanding pulleys and a belt drive.
The 2 element drive fluid coupling could not multiply torque. Torque converters have an part referred to as a stator. This alters the drive's characteristics throughout times of high slippage and produces an increase in torque output.
There are a at least three rotating elements within a torque converter: the turbine, that drives the load, the impeller, which is mechanically driven by the prime mover and the stator, which is between the turbine and the impeller so that it can alter oil flow returning from the turbine to the impeller. Usually, the design of the torque converter dictates that the stator be stopped from rotating under whichever condition and this is where the word stator begins from. Actually, the stator is mounted on an overrunning clutch. This particular design prevents the stator from counter rotating with respect to the prime mover while still enabling forward rotation.
