Squad Truck
Most often a squad truck is a rescue vehicle designed to transport the necessary tools, equipment, and personnel to perform a vehicle extrication at the scene of an entrapment. The squad truck assignment is variable, by department and region, so assigning specific types of apparatus or tasks is very difficult. Vehicle construction The design of squad trucks varies, depending on the geography and need in any given area. Areas with rough terrain or snow usually have squad trucks with four-wheel drive, jake brake, locking differentials, hydraulic brakes, and aggressive tires. Often, squads trucks are old ambulances that have been stripped to carry the necessary tools and equipment needed for an extrication, however, rescue squads or fire departments with a high amount of funding often purchase custom trucks that are more elaborate and functional squad trucks. As such, the size of squad trucks is varying, and can be classified into three distinct categories. Class I, or light duty ...

Hydraulic Rescue Tools
Hydraulic rescue tools, also known as jaws of life, are used by Emergency service, emergency rescue personnel to assist in the vehicle extrication, extrication of victims involved in Traffic collision, vehicle accidents or railway accidents and cutting large-sized debris of mild metal structures into smaller pieces for extraction of injured/dead victims out from building rubble in earthquake-raged areas, as well as other rescues in small spaces. These tools include cutters, spreaders, and rams. Such devices were first used in 1963 as a tool to free race car drivers from their vehicles after crashes. History The Hurst Rescue Tool was invented by George Hurst, circa 1961, after he viewed a stock car race accident in which it took workers over an hour to remove an injured driver from his car. Previously rescuers often used circular saws for vehicle extrication, but these suffered from several drawbacks. Saws can create Spark_(fire), sparks, which could start a fire, create loud s ...

Chain
A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use: * Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus-shaped, which make the chain flexible in two dimensions (the fixed third dimension being a chain's length). Small chains serving as jewellery are a mostly decorative analogue of such types. * Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chains. Two distinct chains can be ...

Comealong
A come-along, also known as a power puller, is a hand-operated winch with a ratchet used to pull objects. The drum is wrapped with wire rope. A similar tool that uses a nylon strap is used to straighten trees, as it straightens gradually over time, therefore not splitting the trunk. Come-alongs are not rated for overhead lifting, but a similar-looking device called a ''ratchet lever'' ''hoist'' is used this way. The original tool of this type was developed by Abraham Maasdam of Deep Creek, Colorado Colorado is a U.S. state, state in the Western United States. It is one of the Mountain states, sharing the Four Corners region with Arizona, New Mexico, and Utah. It is also bordered by Wyoming to the north, Nebraska to the northeast, Kansas ..., about 1919, and later commercialized by his son, Felber Maasdam, about 1946. It has been copied by many manufacturers in recent decades. A similar heavy-duty unit with a combination chain and cable became available in 1935 that was u ...

Flares
A flare, also sometimes called a fusée, fusee, or bengala, bengalo in several European countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground pyrotechnics, projectile pyrotechnics, or parachute-suspended to provide maximum illumination time over a large area. Projectile pyrotechnics may be dropped from aircraft, fired from rocket or artillery, or deployed by flare guns or handheld percussive tubes. Origin The earliest recorded use of gunpowder for signaling purposes was the 'signal bomb' used by the Chinese Song Dynasty (960–1279) as the Mongol-led Yuan Dynasty (1271–1368) besieged Yangzhou in 1276. These soft-shelled bombs, timed to explode in midair, were used to send messages to a detachment of troops far in the distance. Another mention of the signal bomb appears in a text da ...

Traffic Cones
Traffic is the movement of vehicles and pedestrians along land routes. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. (International Regulations for Preventing Collisions at Sea govern the oceans and influence some laws for navigating domestic waters.) Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, cones, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' commo ...

Long Spine Board
A spinal board, is a patient handling device used primarily in pre-hospital trauma (medicine), trauma care. It is designed to provide rigid support during movement of a person with suspected spinal or limb injuries. They are most commonly used by ambulance staff, as well as lifeguards and ski patrollers. Historically, backboards were also used in an attempt to "improve the posture" of young people, especially girls. Due to lack of evidence to support long-term use, the practice of keeping people on long boards for prolonged periods of time is decreasing. Extrication uses The spinal backboard was originally designed as a device to vehicle extrication, remove people from a vehicle. After a time people were simply kept on the spine board for transport without evidence supporting this need. Medical uses A spinal board is primarily indicated for judicious use to transport people who may have had a spinal injury, usually due to the mechanism of injury, and the attending team are not ...

Rope
A rope is a group of yarns, Plying, plies, fibres, or strands that are plying, twisted or braided together into a larger and stronger form. Ropes have high tensile strength and can be used for dragging and lifting. Rope is thicker and stronger than similarly constructed cord, String (structure), string, and twine. Construction Rope may be constructed of any long, stringy, fibrous material (e.g., rattan, a natural material), but generally is constructed of certain natural fibre, natural or synthetic fibre, synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, they have a higher tensile strength, they are more resistant to rotting than ropes created from natural fibres, and they can be made to float on water. But synthetic ropes also possess certain disadvantages, including slipperiness, and some can be damaged more easily by UV light. Common natural fibres for rope are Manila hemp, hemp, linen, cotton, coir, jute, straw, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winch
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension (physics), tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a Bobbin, spool (or drum) attached to a hand crank (mechanism), crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called Capstan_(nautical), capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a Mechanical brake stretch wrapper, mechanical brake or ratchet (device), ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Tower (equipment)
A light tower is a piece of mobile equipment which has one or more high-intensity electric lamps and a mast. Almost always, the lights are attached to the mast, which is attached to a trailer, with a generator set to power the lamps. Normally the lamps are metal-halide lamp, metal halide bulbs and the generator is powered by a diesel engine. However, battery-powered, solar-powered and hydrogen-powered sets are available; light towers with electrodeless lamps lighting are also sold. Modular kits permit separation of the generator set, trailer, lights and mast from each other. Another variation is an inflatable mast. Particularly when an inflatable mast is used, the lights may be placed close to the ground, with a reflector attached to the mast. When soft lighting is wanted, an inflatable "balloon" diffuser may be used. An inflatable mast may serve as a diffuser. Light towers are used when illumination is required but not otherwise available, both outdoor and indoor, usually tempora ...

Plasma Torch
A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. Types Thermal plasmas are generated in plasma torches by direct current (DC), alternating current (AC), radio-frequency (RF) and other discharges. DC torches are the most commonly used and researched, because when compared to AC: "there is less flicker generation and noise, a more stable operation, better control, a minimum of two electrodes, lower electrode consumption, slightly lower refractory eatwear and lower power consumption". Transferred vs. non-transferred There are two types of DC torches: non-transferred and transferred. In non-transferred DC torches, the electrodes are inside the body/housing of the torch itself (creating the arc there). Whereas in a transferred torch one e ...

Cascade Storage System
A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective transfer. The cascade system allows small cylinders to be filled without a compressor. In addition, a cascade system is useful as a reservoir to allow a low-capacity compressor to meet the demand of filling several small cylinders in close succession, with longer intermediate periods during which the storage cylinders can be recharged. Principle of operation When gas in a cylinder at high pressure is allowed to flow to another cylinder containing gas at a lower pressure, the pressures will equalize to a value somewhere between the two initial pressures. The equilibrium pressure is affected by transfer rate as it will be influenced by temperature, but at a constant temperature, ...
