Mobile Crane Blocks
Mobile crane is a popular machine to move heavy materials.
Mobile crane is a machine with hoist rope, chain or wire rope which is used to move heavy materials. It
is a very useful machine and can be used for many industries. For example is in general construction and
During operation, mobile crane operator must consider “rated load” of the machine and load safety
margin to make sure the machine stability.
Mobile Crane Model
We can find many models of mobile crane. Some of them are truck mounted, rough terrain and floating
- Truck mounted crane
The common model for truck mounted crane is a commercial truck chassis with a rotating
telescopic‐boom crane mounted on the backside.
- Rough terrain crane
Rough terrain crane mostly is designed to pick and carry material. It usually has four off‐road
- Floating crane
Floating crane mainly used in building and port construction.
- Crawler crane
Crawler crane has a good stability and mobility.
Mobile Crane Blocks Parts
Here are some main parts of mobile crane blocks:
Boom is a long arm, which is used to lift and move materials.
- Jib arm
Jib arm is lattice‐type structure, which is located at the end of the boom. The function of jib arm
is to provide safe distance between materials with crane main support.
- Rotex gear
The Rotex gear is the mechanism which allows the cab and boom to rotate.
The counterweights are mounted toward the rear of counter deck. The function is to compensate
the weight of the lifted materials. The counterweights are adjustable.
Hook is used to attach the material to the crane.
