Called the Bucket Truck, this particular vehicle has a bucket accessory with an expandable arm used to lift employees high up into the air. Bucket Trucks are even known as Aerial Boom Trucks. They have a lifting capacity of one hundred fifty kilograms to seven hundred kilograms and the bucket itself can 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 back 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 another type of Boom Truck which has a large container on its rear that is made to be able to carry expandable pipe and concrete. Concrete is pumped with the pipe into a certain location. Concrete Boom Trucks are able to be lengthened up to seventy meters.
The most popular kind of torque converter utilized in automobile transmissions is the fluid coupling kind. In the 1920s there was also the Constantinesco or also known as pendulum-based torque converter. There are other mechanical designs for always variable transmissions that could multiply torque. Like for example, the Variomatic is one type that has expanding pulleys and a belt drive.
The 2 element drive fluid coupling cannot multiply torque. Torque converters have an part referred to as a 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, which drives the load, the impeller, which is mechanically driven by the prime mover and the stator, which is between the turbine and the impeller so that it could alter oil flow returning from the turbine to the impeller. Usually, the design of the torque converter dictates that the stator be stopped from rotating under whatever condition and this is where the term stator begins from. Actually, the stator is mounted on an overrunning clutch. This design prevents the stator from counter rotating with respect to the prime mover while still enabling forward rotation.
