Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios .
Most public transit buses in the United States and Canada are equipped with bicycle racks, though they are far less common on transit systems outside North America. [4] [5] Bus-mounted bike carriers are usually attached to the front of the bus, and most are capable of collapsing when not in use. [6] [7] Some buses have rear-mounted racks. [8]
A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck-type carriers or as self-propelled models. [1] They are designed to easily transport [2] to a site and use with different types of load and cargo with little or no setup or assembly.
Disadvantages include: Implementations to date are heavier than those of bicycle chain and sprocket designs.; Though some of the components in a sealed hydraulic system maintain constant efficiency upwards of 95% in all conditions (see hydristor), the overall losses usually result in an efficiency of about 75% (power loss of about 25%, see hydraulic machinery).
The electro-kinetic road ramp is a method of generating electricity by harnessing the kinetic energy of automobiles that drive over the ramp. In June 2009, one of the devices was installed in the car park at a Sainsbury's supermarket in Gloucester, United Kingdom , where it provides enough electricity to run all of the store's cash registers.
Car lift may refer to: Car elevator, a device which transports cars between different floors of a building. Car lift, car hydraulic lift, 2 post lift or 2 column lift, a device which mechanically lifts a car up, so that the mechanic can work underneath. Car ramp, a device which raises a car from the ground for access to its undercarriage.
Travelling by road. The sidelifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis.The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships.
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track.
