Another kind of Boom Truck is called a Bucket Truck. It has a bucket attachment with an expandable arm and specializes in hoisting individuals, typically employees high up in the air. Bucket Trucks are otherwise called 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 larger boom trucks that are outfitted together with a crane on the back part of the equipment. 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 10 tons to 50 tons.
A Concrete Boom Truck is yet another type of Boom Truck which has a big container on its back that is constructed in order to lift concrete and expandable pipe. Concrete is pumped with the pipe into a specific site. Concrete Boom Trucks are able to be extended up to seventy meters.
The fluid coupling model is actually the most popular type of torque converter utilized in car transmissions. In the 1920's there were pendulum-based torque or otherwise called Constantinesco converter. There are different mechanical designs for always variable transmissions which can multiply torque. For instance, the Variomatic is a version that has expanding pulleys and a belt drive.
A fluid coupling is a 2 element drive which cannot multiply torque. A torque converter has an extra part which is the stator. This changes the drive's characteristics all through occasions of high slippage and generates an increase in torque output.
There are a at least three rotating components inside a torque converter: the turbine, which drives the load, the impeller, which is mechanically driven by the prime mover and the stator, which is between the impeller and the turbine so that it can change oil flow returning from the turbine to the impeller. Traditionally, the design of the torque converter dictates that the stator be prevented from rotating under whichever situation and this is where the term stator begins from. In 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.
