Called the Bucket Truck, this particular vehicle has a bucket attachment with an expandable arm used to lift workers high up into the air. Bucket Trucks are even called Aerial Boom Trucks. They have a lifting capacity of 150 kg to 700 kg and the bucket itself can be lengthened up to 10 meters in the air.
Knuckle Boom Trucks are bigger boom trucks that are equipped along with a crane on the rear section of the apparatus. If the length of the truck is expanded, the truck then becomes a Trolley Boom Truck. These kinds of forklifts have a lifting capacity of ten tons to fifty tons.
A Concrete Boom Truck is yet one more type of Boom Truck that has a huge container on its back that is made to lift expandable pipe and concrete. Concrete is pumped with the pipe into a particular site. Concrete Boom Trucks are able to be extended up to seventy meters.
The most popular type of torque converter used in automobile transmissions is the fluid coupling kind. In the 1920s there was even the Constantinesco or likewise known as pendulum-based torque converter. There are other mechanical designs utilized for always changeable transmissions that could multiply torque. Like for instance, the Variomatic is one kind that has expanding pulleys and a belt drive.
The 2 element drive fluid coupling cannot multiply torque. Torque converters have an part called a stator. This changes the drive's characteristics throughout times of high slippage and generates an increase in torque output.
There are a minimum of three rotating elements within a torque converter: the turbine, that 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 can alter oil flow returning from the turbine to the impeller. Traditionally, the design of the torque converter dictates that the stator be stopped from rotating under whatever condition and this is where the term stator originates from. In reality, the stator is mounted on an overrunning clutch. This design prevents the stator from counter rotating with respect to the prime mover while still allowing forward rotation.
