Use And History Of Cranes
Every time we see a crane in action we remains without words, these machines are sometimes really huge, taking up tons of material hundreds of meters in height. We watch with amazement and a bit of terror, thinking about what would happen if the load comes off or if the movement of the crane was wrong. It is a really fascinating system, surprising both adults and children. These are especially tower cranes, but in reality there are plenty of types and they are in use for centuries. The cranes are formed by one or more machines used to create a mechanical advantage and thus move large loads. Cranes are equipped with a winder, a wire rope or chain and sheaves.
The cranes have been used since ancient times, the chimney or fireplace cranes were used to turn the pots and kettles on the fire, while the height was governed by a trammel hook. It is the same principle of cranes that are now in the harbors. The construction of cranes probably has already begun with the ancient Greeks and were then driven by men or beasts of burden, like donkeys. The cranes were then used for the construction of tall buildings, like temples. Later, cranes were built larger, with the use of tread wheels, which allowed to lift much greater weights.
During the Middle Ages cranes were introduced for lifting, loading and unloading ships in harbors as well as aid in their construction. Some of them were even built into stone towers to increase strength and endurance. Indeed, the first cranes were built in wood, but with the advent of the industrial revolution, cast iron and steel quickly supplanted this material.
For many centuries, in fact, the cranes were operated by the force of humans or animals, even if the hoists in the windmills and watermills were driven by the forces of natural agents. The first mechanical cranes were operated by steam engines, and came into use in the 18th or 19th century, many remain active even in the 20th century.
Modern cranes usually use internal combustion engines or electric motors and hydraulic systems to provide a much greater capability to lift weights than in the past. Additionally there are the mobile ones, such as hydraulic cranes, mounted on trucks. However manuals cranes are often still used, for example when the provision of power is not considered very profitable.
There are several forms and varieties of cranes to the present day, each created for a specific use. Sizes ranging from the smallest jib cranes, used in workshops, to the highest tower crane used in the construction of the tallest buildings and the larger floating cranes, used to build oil platforms and recover the sunken ships.

Uses of Overhead Cranes
A Crane is a lifting machine, generally equipped with a winder (also called a wire rope drum), wire ropes or chains and sheaves that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight, in the construction industry for the movement of materials and in the manufacturing industry for the assembling of heavy equipment.
An Overhead Crane is a type of crane where the hook-and-line mechanism runs along a horizontal beam that runs along two widely separated rails. Often it is in a long factory building and runs along rails along the building’s two long walls. It is similar to a gantry crane. Overhead cranes typically consist of a hoist to lift the items, the bridge, which spans the area covered by the crane, and a trolley to move along the bridge.
The most common Overhead Crane use is in the steel industry. Every step of steel, until it leaves a factory as a finished product, the steel is handled by an overhead crane. Raw materials are poured into a furnace by crane, hot steel is stored for cooling by an overhead crane, the finished coils are lifted and loaded onto trucks and trains by overhead crane, and the fabricator or stamper uses an overhead crane to handle the steel in his factory. The automobile industry uses overhead cranes for handling of raw materials. Smaller workstation cranes handle lighter loads in a work-area, such as CNC mill or saw

Cranes
A crane is a tower or derrick that is equipped with cables and pulleys that are used to lift and lower material. They are commonly used in the construction industry and in the manufacturing of heavy equipment. Cranes for construction are normally temporary structures, either fixed to the ground or mounted on a purpose built vehicle.
They can either be controlled from an operator in a cab that travels along with the crane, by a push button pendant control station, or by radio type controls. The crane operator is ultimately responsible for the safety of the crews and the crane.
Medieval cranes Cranes of the Middle Ages were used to build the cathedrals of Europe. The crane was fixed on top of a wall as it was being constructed and was powered by men that ran inside of two large wheels on each side. Cranes were also used in medieval ports and in shipyards.
Mobile cranes The most basic type of crane consists of a steel truss or telescopic boom mounted on a mobile platform, which could be a rail, wheeled, or even on a cat truck. The boom is hinged at the bottom and can be either raised or lowered by cables or hydraulic cylinders.
Telescopic crane This type of crane offers a boom that consists of a number of tubes fitted one inside of the other. A hydraulic mechanism extends or retracts the tubes to increase or decrease the length of the boom.
Tower crane The tower crane is a modern form of a balance crane. When fixed to the ground, tower cranes will often give the best combination of height and lifting capacity and are also used when constructing tall buildings.
Truck mounted crane Cranes mounted on a rubber tire truck will provide great mobility. Outriggers that extend vertically or horizontally are used to level and stabilize the crane during hoisting.
Rough terrain crane A crane that is mounted on an undercarriage with four rubber tires, designed for operations off road. The outriggers extend vertically and horizontally to level and stabilize the crane when hoisting. These types of cranes are single engine machines where the same engine is used for powering the undercarriage as it is for powering the crane. In these types of cranes, the engine is normally mounted in the undercarriage rather than in the upper portion.
Loader crane A loader crane is a hydraulically powered articulated arm fitted to a trailer, used to load equipment onto a trailer. The numerous sections can be folded into a small space when the crane isn’t in use.
Overhead crane Also referred to as a suspended crane, this type is normally used in a factory, with some of them being able to lift very heavy loads. The hoist is set on a trolley which will move in one direction along one or two beams, which move at angles to that direction along elevated or ground level tracks, often mounted along the side of an assembly area.
In the excavation world, cranes are used to move equipment or machinery. Cranes can quickly and easily move machinery into trenches or down steep hills, or even pipe. There are many types of cranes available, serving everything from excavation to road work.
Cranes are also beneficial to building bridges or construction. For many years, cranes have proven to be an asset to the industry of construction and excavating. Crane operators make really good money, no matter what type of crane they are operating.

Getting Big Jobs Done With Small Jib Cranes
There are many different varieties of cranes on the market today, both in terms of size and type. Each type and size serves a different function. In essence, a crane is a machine, which lifts materials up and down as well as horizontally. They are most often used in the construction, manufacturing and transport industries. Cranes are typically used to move and assemble heavy equipment. Crane sizes run the gamut from the enormous ones all the way to much smaller ones which tend to be used in factories and workshops. There are also really tall ones typically used in the construction of tall buildings. The three most common crane types are overhead cranes, gantry cranes and jib cranes.
Jib cranes are a type in which there is a horizontal portion, known as a jib or a boom that supports a hoist, which is moveable. The horizontal member of this type of crane is fixed either to a wall or floor-mounted pillar. Jib cranes are most often used on military vehicles or in industrial facilities. The horizontal jib can either be fixed, or it can swing through in an arcing movement, which provides more lateral movement.
Jib cranes are typically smaller in size, which make them perfect for industrial purposes. Jib cranes are often referred to simply as hoists. This is because they are often installed on an upper floor area of warehouses so they can lift material in the warehouse to any and all floors.
There are several different types of jib cranes, including the wall crane and the hammerhead crane, both of which share many similarities with the boom crane. All of these varieties consist of an arm that suspends a hoist rope, hook and block. The difference between the majority of boom cranes and the jib crane is the fact that jib cranes are not adjustable to maneuver at a specific angle. Rather, a jib crane is locked in a fixed horizontal position.
With all types of cranes, taking the proper safety measures prior to and during operation is vital. This is because cranes can be very dangerous if used improperly by untrained operators, with the consequence being the potential for accidents causing serious injury or even death. Even though jib cranes are among the smaller breed of cranes, proper use and safety is still extremely important. Before engaging in use of a jib crane, you must check it to ensure there are no bent supports and that it is not misaligned at all. Anyone operating a jib crane must be knowledgeable in the jib arm’s range of motion, as well as the location of the Emergency Stop Button and Overload Indicators. An operator must be trained in when and how to use these buttons, along with overall training on the operator of the jib crane.
With the proper experience and training, jib cranes can be extremely safe and useful on any job. Due to their size, they can fit inside many large indoor premises, which require the use of a crane to lift materials onto or from many different levels. Remember to always put safety first when getting the job done.

Houston Octg Looks To Nai For Cranes
North American Industries (NAI) has been selected to design and install two 10-ton Class E top-running overhead cranes for Houston OCTG Group Inc. (Houston). Houston, a wholly-owned subsidiary of WSP Holdings Limited, headquarted in Jiangsu Province, China, manufactures specialty tubing and castings used to transport crude oil and natural gas from an oil or gas layer to the earth’s surface during the drilling process.
Houston asked NAI to inspect the existing cranes in its 1,350 foot long Houston, TX-based facility. After thorough inspection by and extensive consultation with NAI technical personnel, Houston management decided to invest in new cranes. Houston also chose to replace the existing, worn rail to avoid premature damage to the new cranes. Based upon NAI’s recommendation, Houston’s engineering department and project manager chose heavier-duty Class E cranes because they must be capable of handling over 20 lifts per hour.
These double-girder cranes will be used in Houston’s manufacturing process, which includes pipe threading, heat treatment and inspection. They will also be used to load and unload raw materials. Each crane will have two five-ton hoists bolted directly to a 10-ton trolley. The trolley will move along the 79-foot bridge beam, and the entire crane will move along the 1,350-foot runway system.
Lena Banigan, Project Manager/Assistant VP at Houston, states, “NAI has not only been a pleasure to work with but has also provided service to meet our deadlines. In business, time is critical to advancement, and NAI has been truly accommodating.”
“We are pleased to be working with Houston OCTG to meet its overhead lifting needs. We have collaborated closely with Houston’s engineers and senior management to design a system tailored to meet its unique requirements,” comments Craig Pelkola, Director of Technical Sales at North American Industries
Dan Osborn, Engineering Manager at North American Industries, adds, “The project has gone smoothly. We assembled a team of engineers, project managers, operations personnel and field technicians to carefully oversee the design, manufacture and installation of the equipment”.
NAI is a leading manufacturer of industrial overhead cranes, including bridge cranes, gantry cranes, monorails, jib cranes, and custom-engineered systems. With its large, experienced engineering group, technical sales force and over 40 years of manufacturing expertise, the Company is well-positioned to handle the needs of a diverse range of end users.

Truck Cranes
There are few things more frustrating for a truck driver than arriving at a destination to find that there are no facilities available for unloading their cargo. By investing in a truck crane that can be fitted to vehicles in order to make loading and unloading simple, you can improve your distribution efficiency, and also make life much easier for drivers. Fitting a truck crane to your vehicle means that your drivers will be able to offload anywhere, and have a much greater degree of control over all aspects of the distribution of goods. A simple hoist can be installed very quickly and with connection to the standard DC power supply on the truck the lifting system will be able to lift relatively heavy weights up to 2,000 pounds with ease.
The latest truck cranes available are constructed from the finest aircraft grade aluminum and can be fitted to almost any style of truck in order to facilitate loading and unloading. Thanks to their simple and elegant design, the sturdy cranes offer plenty of flexibility in the way that relatively heavy amounts of material can be manipulated. Delivered in a simple to install kit, these cranes offer all the equipment you need in order to get started with lifting straight away.
The standard truck crane offers a reach of up to 87 inches depending on specification, and boasts an adjustable jib with easy to use controls that ensure even on the first time of use the operator will find it simple to carry out the process safely and without any accidents. The ease with which the highly responsive fingertip controls allow for the operator to lift objects makes for light work that is precise and clean.
The flexibility which these cranes offer is probably best demonstrated by virtue of the fact that they can be installed virtually anywhere – you are not just limited to having them on a truck. With appropriate fittings, the static upright support can be fastened to almost any flat surface including concrete, allowing for these cranes to operate under a range of different circumstances including within a factory or warehouse. When installed in any environment you can enjoy the world class build quality of the cranes, and appreciate the ease with which heavy loads can be manipulated with ease.
Thanks to their innovative folding design, which means that the cranes are able to be stowed out of the way when not in use, reliable motors that offer power as and when it is required, and the ability for them to lift sizable amounts of material with ease, these truck cranes are likely to be extremely useful in almost any situation. Manufactured to the highest standard, and fully compliant with ANSI and OSHA specifications, these high quality truck cranes are available in a variety of options that are able to operate on either 12V DC power or 115 V AC depending on the installation.
Commercial and industrial jib & gantry cranes are key components to any company’s inventory. Choosing the right jib or gantry crane for the right project not only saves on time, but also may save lives.
