'''What’s
a
jib
crane
?'''
+
Hello, world. I’m Dong,
a
machine geek, who is extremely interested in mechanical design and now working as a crane engineer in a Chinese
crane
enterprise.
−
Jib crane is a kind of small and medium sized lifting equipment with unique structure. Its lifting system is fixed at the end of its arm or travel along the arm; its arm can rotate but can’t be lifted up.
+
−
'''Features
of jib
crane'''
+
Every and each day, I deal with all kinds
of
cranes, such as, overhead cranes, also called bridge cranes or EOT cranes, and bridge cranes,
jib
cranes, gantry cranes, ports cranes, and various hoists. Therefore, if you have any problems or confusion on material handling, please come to Dong, who is always willing to help.
−
Jib
crane
have many good features
like
safety
and
reliability, high efficiency, energy-saving,
and
operating flexibly which can largely save manpower
and
work time
.
+
As a
crane
engineer, I’d
like
to share valuable information on cranes for I’d like to help those who need helps
and
do my little contribution
and
make me feel meaningful
and
connected with the world
.
It’s a lonely
and
crowded world, don’t you think so?
−
Jib crane can be operated easily in 3-D space. It can be used in many different sites of different industries
and
performs better than most of other common lifting machines in sites that requires short-distance and intensive lifting.
+
−
The workload of jib crane is relevant low; usually its lifting capacity can be 16 ton at most.
+
−
'''General compositions of jib crane

Dong
is
new here! Would you please help me to get more friends here? Follow me
,
please. You will know a different world
,
not only on material handling but also
on
China
,
Chinese people
,
Chinese culture
,
etc
.

'''
+
−
It
is
composed of pillar
,
rotating arm
,
rotating driven system and electric hoist. The pillar is fixed
on
concrete ground with anchor bolt
,
and the arm is driven to rotate by cycloid gear reducer
,
the electric hoist travels horizontally on the steel I-beam of the arm and lifts up heavy load. The pillar of jib crane is a hollow steel structure with light dead weight
,
long span, heavy lifting capacity which is economic and reliable
.

−
'''Why use jib crane'''
+
−
Lift and transfer: Dongqi Jib Cranes
lift
and transport loads in semi-circles and full circles with the jib rotating around the support around 200 degrees and 360 degrees.
+
A chance to
lift you
up!
−
Handle material at wherever
you
want: Because of the jib boom, the handling tools such as manual and electric hoists, manipulators, balancers, and welding wire feeders, etc., can travel easily on trolleys along the boom.
+
−
Save your working space
to
large extend: The wall-mounted jib crane takes no floor space, which can save your working space.
+
A bridge
to
a mysterious country!
−
Take advantages of what you have: On designing your crane, we will take full consideration your working conditions and lifting requirements. On some design, we can take the advantages of your building columns or overhead beams to mount the jib cranes, lowering your cost.
+
−
Indoor/Outdoor application: Pillar jib cane also called free-standing crane can be used indoor and outdoor.
+
−
Cooperate with your existing cranes: Jib cranes can work together with your overhead crane. The jib of jib crane can fold and stay out of the way of large overhead cranes.
+
−
'''How
to
choose
your
jib crane'''
+
An opportunity
to
make
your
life better!
−
A suitable jib crane can improve the efficiency of material handling and work flow production. How to choose the right jib crane for your application? Dongqi Crane gives you the follow suggestion for your reference

''Lifting capacity''
+
−
+
−
The maximum weight of your application must not equal or exceed the weight of your crane. When defining your lifting capacity of your jib crane, it should be accounted in the following way:
+
−
+
−
+15% for the weight of the hoist and trolley
+
−
+15% for the deflection of hoist and trolley
+
−
+25% capacity allowance for impact
+

Degree of Rotation''
+
−
+
−
Pillar jib crane offers up to 360 degree rotation.
+
−
Wall mounted jib crane offers up to 180 degree rotation.
+
−
+
−
Outreach Range
+
−
+
−
The outreach range of jib crane refers to the distance from the boom tip to the crane hook, which also is the working area needed.
+
−
+
−
''Crane Height''
+
−
+
−
The height of jib crane has the attachments such as electrical entries included.
+
−
+
−
''Under Boom Height''
+
−
+
−
The under boom height refers to the distance from the floor to the underside of the boom, which will determine the type of hoist required
.
+
−
+
−
''Installation''
+
−
+
−
Location of crane will decide the type of crane as the pillar jib crane needs concrete foundations which may cost more than the jib crane sometimes
