Another type of Boom Truck is referred to as a Bucket Truck. It has a bucket attachment together with an expandable arm and specializes in lifting people, normally staff up in the air. Bucket Trucks are even 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 a lot larger lift vehicles that are equipped together with a crane on the rear of the apparatus. If the length of the vehicle is expanded, then the truck 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 one more kind of Boom Truck that has a large container on its rear that is constructed to carry concrete and expandable pipe. Concrete is pumped with the pipe into a specific place. Concrete Boom Trucks are able to be lengthened up to 70 meters.
The fluid coupling type is the most common type of torque converter used in car transmissions. During the 1920's there were pendulum-based torque or also called Constantinesco converter. There are other mechanical designs utilized for continuously variable transmissions that have the ability to multiply torque. For example, the Variomatic is one version which has expanding pulleys and a belt drive.
The 2 element drive fluid coupling could not multiply torque. Torque converters have an component known as a stator. This alters the drive's characteristics through times of high slippage and generates an increase in torque output.
There are a minimum of three rotating elements in a torque converter: the turbine, which drives the load, the impeller, that is mechanically driven by the prime mover and the stator, which is between the turbine and the impeller so that it could change 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 whatever situation and this is where the word stator starts from. In truth, 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 permitting forward rotation.
