Wide-ranging cranes are available for construction works

Construction cranes are valuable and essential properties for the
construction industry. Cranes have some vital jobs on construction
sites, especially when tall buildings, bridges, skyscrapers, etc.
are constructed. Nowadays different types of constructions are done
in odd places like in the middle of a river, or in a busy traffic
area, where works can be smooth-sailing with the help of
construction cranes. Utility of construction cranes Before cranes,
construction industry worked differently as everything required
human labor. Lifting, loading, unloading and shifting were done by
laborers. It required lots of time and labor. The process was
expensive too. The construction industry in many places needed to
restrict their imagination and design due to lack of labor or
expertise. These problems are readily solved ever since
construction cranes were invented. It saves much time, labor and
money of contractors or owners of buildings. Modern day
construction cranes possess a huge capacity and a great many
utilities. Types of construction cranes Various types of cranes are
used depending on the requirements of the work and site location.
Here are the mostly used construction cranes: Tower cranes - These
cranes are required in building skyscrapers, bridges, and tall
buildings. Tower cranes are normally fixed on the construction site
with a strong base as long as construction works proceeds. They
rise hundreds of feet above and can also reach out hundreds of feet
horizontally. Tower cranespossess18-20 tons lifting capacity.
Truck-mounted cranes – As the name suggests, these cranes are
mounted on a vehicle and easily movable from one location to
another. These cranes have two parts: the carrier where the crane
is fixed which is also called lower, and the lifting component
called upper. A truck-mounted crane possesses 13-14.5 tons
capacity. Rough terrain cranes – It is a specialized form of
thetruck-mounted crane where the tiers of the carrier are specially
built for moving on an uneven surface. Outriggers are used in these
cranes so that the system remains firm while loading and unloading.
These cranes generally possess 35-80 tons lifting capacity. Crawler
Cranes – A crawler crane is almost like rough terrain crane but it
possesses crawlers or tracks for movement. The crawlers provide
sufficient stability to this cranes, hence, they don’t come with
outriggers. Crawler cranes possess high lifting capacity which
starts from 40 tons. Railroad cranes – As the name suggest, these
cranes are mobile but only on the railway tracks. They possess
flanged when suitable for movement on the track. The lifting
capacity of these cranes generally varies from 15-250 tons. Aerial
cranes – These are the most modern addition to this product line.
Aerial cranes are actually helicopters that carry loads to a great
height or in an odd site like is a mountain site or in the middle
of a river. Besides, telescopic cranes, floating cranes, level
luffing cranes, etc. are also used in different construction sites.
Again, contractors may require more than one types of cranes to
work simultaneously. Cranes make any construction work rather easy
and inexpensive than manual or semi-manual works. However, proper
training for operation and safety is required while working with
the cranes.
