Spotter (maneuvering)
A spotter is a person used in vehicle maneuvers to assist a driver who may not have a clear view in their direction of travel. They are most commonly used in: * Off-road rock crawling * Reversing truck and trailer combinations, such as semitrailers, b-trains and road trains * Placing oversized freight using a forklift * Lifting loads using a vehicle-mounted crane (loads lifted using a fixed crane are supervised by a banksman In Irish and British civil engineering, a banksman is the person who directs the operation of a crane or larger vehicle from the point near where loads are attached and detached. The term 'dogman' may be used in Australia and New Zealand, while 's ...) * Guiding military vehicles (also called ''ground guiding'') * Dumping materials, such as from a dump truck * Guiding oversized loads. The spotter's advantage is the ability to move around the load or vehicle to determine the best trajectory. A spotter will either use a set of standard hand signals, or will a ...

Off-roading
Off-roading is the activity of driving or riding in a vehicle on unpaved surfaces such as sand, gravel, riverbeds, mud, snow, rocks, and other natural terrain. Types of off-roading range in intensity, from leisure drives with unmodified vehicles, to competitions with customised vehicles and professional drivers. Off-roaders have been met with criticism for the environmental damage caused by their vehicles. There have also been extensive debates over the role of government in regulating the sport, including a Supreme Court case brought against the Bureau of Land Management in the United States. Off-road vehicle Travelling over difficult terrain requires vehicles capable of off-road driving such as ATVs. These vehicles have features designed specifically for use in off-road conditions such as extended ground clearance, off-road tires and a strengthened drive-train. Some manufacturers offer vehicles specifically designed for off-road use. Recreational off-roading Some e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Train
A road train, land train or long combination vehicle (LCV) is a trucking vehicle used to move road freight more efficiently than semi-trailer trucks. It consists of two or more trailers or semi-trailers hauled by a prime mover. History Early road trains consisted of traction engines pulling multiple wagons. The first identified road trains operated into South Australia's Flinders Ranges from the Port Augusta area in the mid-19th century. They displaced bullock teams for the carriage of minerals to port and were, in turn, superseded by railways. During the Crimean War, a traction engine was used to pull multiple open trucks. By 1898 steam traction engine trains with up to four wagons were employed in military manoeuvres in England. In 1900, John Fowler & Co. provided armoured road trains for use by the British Armed Forces in the Second Boer War. Lord Kitchener stated that he had around 45 steam road trains at his disposal. A road train devised by Captain Charles Renard of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forklift
A forklift (also called lift truck, jitney, hi-lo, fork truck, fork hoist, and forklift truck) is a powered industrial truck used to lift and move materials over short distances. The forklift was developed in the early 20th century by various companies, including Clark Material Handling Company, Clark, which made Transmission (mechanics), transmissions, and Yale Materials Handling Corporation, Yale & Towne Manufacturing, which made Hoist (device), hoists. Since World War II, the use and development of the forklift truck have greatly expanded worldwide. Forklifts have become an indispensable piece of equipment in manufacturing and warehousing. In 2013, the top 20 manufacturers worldwide posted sales of $30.4 billion, with 944,405 machines sold. History The middle nineteenth century through the early 20th century saw the developments that led to today's modern forklifts. The forerunners of the modern forklift were manually-powered hoists that were used to lift loads. In 1906, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksman
In Irish and British civil engineering, a banksman is the person who directs the operation of a crane or larger vehicle from the point near where loads are attached and detached. The term 'dogman' may be used in Australia and New Zealand, while 'spotter' is the more common term in United States. Offshore & Oil and Gas The general term for a professional banksman offshore is a ‘rigger’ or deck crew. A team of riggers will manage lifting operations. There are specific methods, pieces of equipment, and safety protocol for many different types of loads. Offshore, on rigs or vessels, most equipment and materials will arrive on location, transferred by boat utilising a crane, therefore banksmen play an important role in the marine and offshore industries. Contemporary Crane or large vehicle drivers do not always have clear visibility of the loading area, especially when tower crane A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, a ...

Backup Camera
A backup camera (also called a reversing camera or rear-view camera) is a special type of video camera that is produced specifically for the purpose of being attached to the rear of a vehicle to aid in backing up and to alleviate the rear blind spot. It is specifically designed to avoid a backup collision. The area directly behind vehicles has been described as a "killing zone" due to associated accidents. Backup cameras are usually connected to the vehicle head unit display. A common variant is a Surround View system, which assembles a synthetic but positionally accurate top-down view of the vehicle and its adjacencies. Backup cameras have been regulated by specific law in Canada and the United States since 2018. Function The design of a backup camera is distinct from other cameras in that the image is horizontally flipped so that the output is a mirror image. This is necessary because the camera and the driver face opposite directions, and without it, the camera's right would ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
