One more kind of Boom Truck is referred to as a Bucket Truck. It has a bucket attachment along with an expandable arm and specializes in hoisting people, typically workers high up in the air. Bucket Trucks are also known as Aerial Boom Trucks. They have a lifting capacity of 150 kg to 700 kg and the bucket itself could be expanded up to 10 meters in the air.
Knuckle Boom Trucks are bigger boom trucks that are outfitted along with a crane on the rear part of the apparatus. If the length of the truck is expanded, the truck then becomes a Trolley Boom Truck. These kinds of lift trucks have a lifting capacity of ten tons to fifty tons.
A Concrete Boom Truck is yet one more type of Boom Truck which has a huge container on its rear that is constructed so as to lift concrete and expandable pipe. Concrete is pumped with the pipe into a specific location. Concrete Boom Trucks could be lengthened up to seventy meters.
The most common type of torque converter used in car transmissions is the fluid coupling model. In the 1920s there was even the Constantinesco or pendulum-based torque converter. There are other mechanical designs used for constantly variable transmissions that can multiply torque. For example, the Variomatic is a type which has a belt drive and expanding pulleys.
A fluid coupling is a 2 element drive that is incapable of multiplying torque. A torque converter has an additional part that is the stator. This alters the drive's characteristics all through occasions of high slippage and generates an increase in torque output.
There are a minimum of three rotating components in a torque converter: the turbine, which drives the load, the impeller, that is mechanically driven by the prime mover and the stator, that is between the impeller and the turbine so that it could alter oil flow returning from the turbine to the impeller. Normally, the design of the torque converter dictates that the stator be stopped from rotating under any situation and this is where the word stator begins from. Actually, 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 permitting forward rotation.
