Cranes and hoists have revolutionized the modern industrial world

Cranes and hoists have a long history dating back to about 515 BC when they are believed to have been used for moving stone blocks for construction of places of worship or temples. However, now cranes and hoists have become one of the essential gadgets in this modern industrial world. Varieties of cranes have now been introduced to meet the needs of a cross-section of industries. Some of the popular varieties of cranes used by the modern industries are terrain cranes, tower cranes, jib cranes, railroad cranes, harbor cranes to name a few of the popular varieties.

Three elements:

Although the use of cranes is specific to the industry, most of the modern industries make use of jib cranes because of their versatile utility. These cranes consist of three essential elements namely a horizontal jib which in fact, is the projecting arm of the crane. Secondly, a movable hoist mounted on the jib and the third element is the pillar which is mounted on the floor or it may also be fixed to a wall.

The process of moving the material:

Jibs are designed to be operated by hand or an electric motor. The jib cranes are designed to lift the object vertically with the help of a hook which is attached to a chain or metallic rope. Thereafter, either by a manual or mechanical operation, the jib is moved and the material is lowered from the hoist and this process is called slewing the load.

Jibs for shooting movies:

The jibs are available in different models and with varying features. Some of the popular models of jibs are wall mounted, mast type and free standing jibs. In fact, now an exclusive type of mobile jib has been introduced. This type of crane or jib is normally used in shooting movies. In this type of jib a camera is mounted at the required position and the jib is moved on a specially designed track.

Freestanding bridge crane:

Apart from the jibs, a freestanding or workstation bridge crane is another popular variety of lifting tool normally used in an industrial or manufacturing unit. The freestanding bridge crane is an overhead crane which moves on parallel bars or runways. A bridge with hoist moves on the parallel bars. The hoist lifts the material and moves it to the other end of the bridge.

Moving sacks made easy:

The utility of lifts is now further extended to moving sacks containing either raw materials or finished products. For this purpose, exclusive sack vacuum lifters will be employed. This type of lift is capable of moving sacks made of cloth, plastic or even paper of varying capacities.

Vacuum lifts:

Apart from these, a vacuum lifting equipment is another variety of lift which is exclusively used in modern manufacturing processes. In some of the manufacturing processes varieties of round, corrugated, flat shaped materials with varying sizes and weight may have to be lifted, tilted, moved and even rotated in certain predetermined directions as a part of the manufacturing process. For such operations, exclusive vacuum lifts are employed.

Assurance on quality:
