Terex THS15 Motorscraper
The Terex THS15 Motorscraper was a concept machine scraper displayed for the first time at Minexpo 2000. This machine features some unusual design concepts, including an adjustable cutting edge on the bowl to reduce friction when loading. Other notable features were the rear-mounted drivetrain (there was no engine on the front module) and a hydrostatic transmission, which featured hydraulic wheel motors. At least two prototypes were made, and these featured noticeable differences in front end styling. A digital copy of the brochure for this machine is available through ozebooks. Both the THS15 scrapers were spotted for sale in used machinery dealers by 2011 and their fate is unknown. Terex never went ahead with production and subsequently abandoned motor scraper manufacture altogether. Transmission Hydrostatic transmissions have many benefits; however, they are not usually suited to machines that travel at higher speeds over longer distances. The hydrostatic drive may have been a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Tractor-scraper
In civil engineering, a wheel tractor-scraper (also known as a Tournapull) is a type of heavy equipment used for earthmoving. It has a pan/hopper for loading and carrying material. The pan has a tapered horizontal front cutting edge that cuts into the soil like a carpenter's plane and fills the hopper which has a movable ejection system. The horsepower of the machine, depth of the cut, type of material, and slope of the cut area affect how quickly the pan is filled. When full, the pan is raised, the apron is closed, and the scraper transports its load to the fill area. There the pan height is set and the lip is opened (the lip is what the bottom edge of the apron is called), so that the ejection system can be engaged for dumping the load. The forward momentum or speed of the machine affects how big an area is covered with the load. A high pan height and slow speed will dump the load over a short distance. With the pan set close to the ground, a higher speed will spread the ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MINExpo International
MINExpo International is a trade show sponsored by the National Mining Association. The show exhibits the latest mining and minerals processing technologies, and state-of-the-art machinery and equipment for the coal, metal and nonmetal mining processing industries. History MINExpo International is held every four years and has been held at the Las Vegas Convention Center The Las Vegas Convention Center (commonly referred to as LVCC) is a convention center in Winchester, Nevada. It is owned and operated by the Las Vegas Convention and Visitors Authority. As one of the largest convention centers in the world, it h ... since 1996.

Hydrostatic Transmission
A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant Revolutions per minute, RPM while the vehicle moves at varying speeds. CVTs are used in cars, tractors, Side-by-side (vehicle), side-by-sides, motor scooters, snowmobiles, bicycles, and Heavy equipment, earthmoving equipment. The most common type of CVT uses two pulleys connected by a Belt (mechanical), belt or Chain drive, chain; however, several other designs have also been used at times. Types Pulley-based The most common type of CVT uses a V-belt which runs between two variable-diameter pulleys. The pulleys consist of two cone-shaped halves that move together and apart. The V-belt runs between these two-halves, so the effective diamete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Motor
A hydraulic motor is a mechanical actuator that converts hydraulics, hydraulic pressure and flow into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic cylinder as a linear actuator. Most broadly, the category of devices called hydraulic motors has sometimes included those that run on hydropower (namely, water engine, water engines and water motors) but in today's terminology the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery. Conceptually, a hydraulic motor should be interchangeable parts, interchangeable with a hydraulic pump because it performs the opposite function - similar to the way a DC electric motor is theoretically interchangeable with a DC electrical generator. However, many hydraulic pumps cannot be used as hydraulic motors because they cannot be backdriven. Also, a hydraulic motor is usually designed for working pre ...

Excavator
Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators which use winches and steel ropes to accomplish the movements. Terminology Excavators are also called diggers, JCBs (a proprietary name, in an example of a generic trademark), mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK and Ireland, wheeled excavators are sometim ...

Dumptruck
A dump truck, known also as a dumping truck, dump trailer, dumper trailer, dump lorry or dumper lorry or a dumper for short, is used for transporting materials (such as dirt, gravel, or demolition waste) for construction as well as coal. A typical dump truck is equipped with an open-box bed, which is hinged at the rear and equipped with hydraulic rams to lift the front, allowing the material in the bed to be deposited ("dumped") on the ground behind the truck at the site of delivery. In the UK, Australia, South Africa and India the term applies to off-road construction plants only and the road vehicle is known as a tip lorry, tipper lorry (UK, India), tipper truck, tip truck, tip trailer or tipper trailer or simply a tipper (Australia, New Zealand, South Africa). History The dump truck is thought to have been first conceived in the farms of late 19th century western Europe. Thornycroft developed a steam Garbage truck, dust-cart in 1896 with a tipper mechanism. The first motori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
