Another type of Boom Truck is referred to as a Bucket Truck. It has a bucket attachment along with an expandable arm and specializes in lifting individuals, usually staff up in the air. Bucket Trucks are likewise called Aerial Boom Trucks. They have a lifting capacity of 150 kg to 700 kg and the bucket itself could be lengthened up to 10 meters in the air.
Knuckle Boom Trucks are a lot bigger lift vehicles that are outfitted with a crane on the rear of the machinery. If the length of the vehicle is expanded, then the truck becomes a Trolley Boom Truck. These types of forklifts have a lifting capacity of 10 tons to 50 tons.
Another type of Boom Truck the Concrete Boom Truck which is a big container on its back. These are constructed to carry concrete and to carry expandable pipe. Concrete is pumped with the pipe into a certain place. Concrete Boom Trucks could be extended up to 70 meters.
The fluid coupling type is the most common type of torque converter utilized in car transmissions. During the 1920's there were pendulum-based torque or likewise called Constantinesco converter. There are various mechanical designs used for continuously variable transmissions which have the ability to multiply torque. For instance, the Variomatic is one kind that has expanding pulleys and a belt drive.
A fluid coupling is a 2 element drive that cannot multiply torque. A torque converter has an extra component that is the stator. This alters the drive's characteristics through times of high slippage and produces an increase in torque output.
There are a at least three rotating parts in a torque converter: the turbine, that 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 can change oil flow returning from the turbine to the impeller. Usually, the design of the torque converter dictates that the stator be prevented from rotating under any situation and this is where the term stator originates 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 allowing forward rotation.
