Lets Talk About Different Types of Cranes
Crane is comprehensive material handling equipment used to lift heavy objects and place them to the suitable points with the help of lifting force. Moreover, it works with the help of a hoist, sheaves, chain or wire ropes and these parts play an important role for the completion of task. Crane may vary from purpose to purpose and shape to shape and more functionally these can be mobile or immobile. Some of the common types of cranes are given below for your easiness.
Boom CraneIt is one of the common types of crane which can be easily mobilize and fitted on the truck. Boom crane is also known as loader crane because the main function of the crane based on hydraulic boom arm. It is quite similar to the hydraulic excavator and works not with more differentiation than excavator. It holds the weight from one place and drops it to the destination. China is biggest exporter for Boom Crane from many years with unbeatable quality and besides them the great manufacturers are Caterpillar, Tadano and JCB.
Crawler CraneCrawler crane is not so common but it is used for highly construction purposes because of its surface manageable tracks instead of rubber tires. Crawler cranes are one of the most comprehensive resources to construct freely with mobilization of objects far away from site. Crawler crane is only crane that can hold up to 35000 tons weight at a time but the compulsion which made it lacked is low-speed immobility.
Gantry CraneGantry crane is one of the simplest cranes mostly used while mining because it has rail mounted track and can’t mobilize without site. It has a horizontally movable trolley fixed on the beams called girders and the second big purpose of this crane can be seen in large industries where it holds big but leveled boxes.
Jib CraneJib cranes are fixed base cranes fitted usually on floors or walls and can be seen mostly in the industries and army vehicles. The quite interesting thing is that it has fixed moveable ratio and because of its fixed boom it can only move in horizontal structures. Jib cranes are the simplest cranes that are mostly designed on trucks and not so many manufacturers are available that dedicatedly manufacture jib cranes.
Tower CraneThe majorly used crane is tower crane which can be seen on most of the construction sites performing different functions and speeds up the processes of construction. It increases the construction speed as measurable accuracy you will find because of its long structural boom specially designed for moving heavy objects from destination to destination. It is fixed structural mounted type of crane usually found while construction of building or on giant buildings and it can be easily collapsed after the work done.
Truck CraneA vehicle mounted crane is used for fast mobilization and can be used everywhere. Normally, electricity companies use this type of crane to reach out the wires and poles and secondly it can be seen as car lifting machine. Truck crane have also hydraulic boom, bucket and fixed base. The largest manufacturer of truck cranes are China as usual.
Crane PartsAs like crane is one of the most useful construction equipment so it has some useful parts that make it comprehensive under other construction machineries. Some of the common crane parts are as follows:
Boom is most important part of crane used for main purpose for which the crane made. You may recognize the type of crane by its boom. It is a steel beam used as arm to hold the load.
Outriggers are used to balance the crane when there is heavy load on one side and it can be mostly seen on the truck cranes while working on irregular surfaces.
Winch more frequently used to hold the cables or wire ropes and move them up and down when necessary.
Rotex Gear is the gear installed beneath the cab used for rotation of cab and boom on angles that are defined. Rotex gear is the most usual part of truck cranes.
Hydraulic Ram is fixed with the boom acts as a hydraulic piston which extends and retracts the position of boom-arm.
Counterweights used to stabilize the crane while it is carrying the load and it is one of the necessary parts of crane.
Cables & Hooks can be found around the crane’s boom are necessary parts used to keep, hold and drop the loads.
Crane is king of construction equipment used to holds tons of load without any interruption. Behemoths of the crane manufacturing are Tadano, JCB, Caterpillar, Kobelco, Kato, Cargotec and Liebherr. Besides them, the largest crane manufacturing countries are China, Japan, United States and some other Pacific Asian regions.
