Lifting crane – machine originating in antiquity

The ancient Greeks (around the 6th century BC) are considered the inventors of the crane for lifting heavy loads. These hoists needed rope winches and multi-roller hoists to move tons of weights. The Romans developed the concept further. Pulley with three rollers, reel, hoisting boom and rope were the parts of the first Roman cranes. If a pedal wheel replaced the reel, even larger loads could be lifted. Wooden lifting towers and several anchor winches meant another step. In the Middle Ages, the temporarily forgotten Tretrad came back into fashion in an improved form. Meanwhile, modern cranes are used worldwide machines throughout construction as well as transport equipment for heavy loads indoors and outdoors. They can be seen on construction sites as well as at the freight yard or in the container port. Lifting cranes can handle payloads from a few hundred kilos to over a hundred tons. The lifting and lowering of heavy parts is also possible in several directions, ie in the three-dimensional range. From mobile crane to crawler crane to tower crane, there are a variety of designs. In addition there is the division into electric crane or hydraulic crane. On crane is subject to strict safety regulations. Below information about the crane , his models and possibilities.

Lifting crane – type vehicle and loading crane

A crane is, generally speaking, a device capable of changing or loading particularly heavy loads. Depending on the application and the application, different types of cranes are used. Here, too, the question of „buying or renting?“ Anyone who just wants to move loads for a construction site at short notice can always find the right one crane rent. Who z. For example, if you have a car repair shop or a construction business, it’s worth considering buying a suitable crane. Boom position (eg 15 to 70 degrees), hook height (eg 30 m) and load capacity (up to hundreds of tons) are important criteria.
Vehicle and loading cranes are widespread and are among the most common types of cranes. They are predominantly hydraulically operated. Mobile cranes are widespread in the construction business. If no viable cranes are available on-site, vehicle and loader cranes are used in the form of All Terrain multi-axle trucks. Hydraulically extendable telescopeBoom or lattice boom (higher loads) are represented. The most important thing about cranes is their mobility.
There are fast-moving, slow-moving, all-terrain mobile cranes and crawler cranes. All these mobile cranes are also subject to the regulations of the Highway Code.

Other interesting crane types

Swing cranes such as ceiling, column or wall crane and a so-called derrick crane are very versatile. The Derrick crane with its small footprint and a horizontal swivel range to z. B. 220 degrees is well suited to dismantling other cranes. Column cranes have proven themselves in gearbox production, among others. Fixed with special compact anchors, several such overhead cranes in one operation can enormously accelerate the workflow.
A gantry crane spans the respective work area like a portal. The stationary crane usually runs on two parallel rails. Various trolleys with lifting gear travel along the crane bridge. This type of crane can lift heavy loads between its supports. Therefore, sites are mainly freight transhipment sites, assembly halls and shipyards.
The tower crane is also called tower crane, because a built-in turntable allows special variants in the movement. There are tower cranes rotating up and down, because the slewing gear is either at the top or bottom of the crane tower. Untendreher are particularly easy to assemble and disassemble.
