One more type of Boom Truck is called a Bucket Truck. It has a bucket accessory together with an expandable arm and specializes in hoisting individuals, usually staff up in the air. Bucket Trucks are also called Aerial Boom Trucks. They have a lifting capacity of one hundred fifty kilograms to seven hundred kilograms and the bucket itself could be expanded up to 10 meters in the air.
Knuckle Boom Trucks are larger boom trucks which are outfitted along with a crane on the back part of the apparatus. If the length of the truck is expanded, the truck then becomes a Trolley Boom Truck. These types of lift trucks have a lifting capacity of 10 tons to 50 tons.
A Concrete Boom Truck is yet another kind of Boom Truck which has a big container on its back that is constructed to be able to carry concrete and expandable pipe. Concrete is pumped with the pipe into a certain place. Concrete Boom Trucks can be lengthened up to 70 meters.
The fluid coupling kind is the most popular type of torque converter used in car transmissions. During the 1920's there were pendulum-based torque or otherwise called Constantinesco converter. There are different mechanical designs for continuously variable transmissions that could multiply torque. For example, the Variomatic is a version that has a belt drive and expanding pulleys.
A fluid coupling is a 2 element drive which could not multiply torque. A torque converter has an additional element which is the stator. This changes the drive's characteristics throughout times of high slippage and produces an increase in torque output.
In a torque converter, there are a minimum of three rotating components: the turbine, to drive the load, the impeller which is driven mechanically driven by the prime mover and the stator. The stator is between the turbine and the impeller so that it can alter oil flow returning from the turbine to the impeller. Normally, the design of the torque converter dictates that the stator be prevented from rotating under whichever situation and this is where the word stator begins from. In point of fact, the stator is mounted on an overrunning clutch. This particular design stops the stator from counter rotating with respect to the prime mover while still enabling forward rotation.
