The flat top tower crane features stable operation and reliable
management due to the adoption of various advanced technologies. It
is configured with diverse devices like the hydraulic
self-propelling device, frequency converting slewing device and a
series of reliable safety devices like hoisting height limiter,
slewing range limiter and multifunctional limiter. It is thus easy
for this heavy lifting equipment to control the hoisting capacity,
load moment and trolley traveling range more precisely.
Additionally, multiple electric safety devices such as anemoscopes
and obstacle lights effectively prevent the breaking of trolley
axles.The PLC (Programmable Logic Controller) adopted by our aerial
equipment can timely diagnose the cause of breakdowns. The
frequency converter easily realizes continuously variable speed
regulation and greatly improves the stability, reliability, and
operability of the control system as well as the work efficiency of
the flat top tower crane. QTP5010-5 Tower Crane is a new
type of construction tower equipment that is researched and
designed by Institute of Building Mechanization of China Academy of
Building Research based on large formwork construction technology.
It has the following characteristics:1) Lifting multiplying factor
switchover automatically, without operator's intervention. 2)
Ahead of all domestic competitors, we are the first
manufacture to adopt lifting rope verticality limit mechanism,
which decreases the lifting rope vertical angle under free load
lifting mode, and highly improves the tower crane steering
performance. 3) Our tower sections are exchangeable, which
provide our customers more conveniences. 4) We adopt to use
Dual drawbars structure on lifting boom, which enables the lifting
boom to be under no stress at lifting surface other than uniaxial
stress, and moreover, it gets rid of the stress peak. It greatly
improves the fatigue safety performance of lifting boom. 5)
Adopts VVVF stepless speed variation device for lifting, radius
changing and slewing mechanisms, to make sure it works steadily and
effectively, it also lowers the maintenance cost. 6) The
equipment adopts to use non-contact computer control system, which
provides the high reliability and full functions to avoid drivers'
miss-operation. 1.Performance parameters of QTP5010-5:
performance parameters and technical indexes reach both domestic
and international advanced level.• Max. jib length: 50m; Jib length
under different assembling modes can decrease progressively by 5
meters and the Min. jib length is 40 meters.• Max. lifting capacity
5t;• Max. hoisting capacity at jib tip: 1t;• Max. lifting moment
500 t.m;• Max. free-standing height: 30m; Max. working height of
anchored crane: 120m;• Hoisting mechanism power: 18/18/5 KW; rope
capacity: 320m;• Slewing mechanism power: 3.7KW• Trolleying
mechanism power: 3.3/2.2 KW• Types of tower crane: stationary crane
with embedded outriggers, stationary crane with embedded bolts,
stationary crane with under-frame and mobile tower crane.2.
Electrical control systemWith PLC control, the electrical control
system enjoys better reliability and safety. Produced by
professional manufacturers with advanced foreign technology, the
electrical elements feature service lives that are 3 or 4 times
longer than that of domestic products, less faults, easy
maintenance and repair as well as reliable operation.3. Technical
features• TThe crane boasts of multiple operation modes and wide
application. The crane can work in different forms: stationary
crane with embedded outriggers, stationary crane with under-frame,
stationary crane with embedded bolts and crane anchored to wall,
thus being applicable to various construction projects.• The
complete machine adopts internationally well-received beautiful
shape;• The crane features high working speed and excellent speed
regulation performance. Stepless speed regulation by frequency
control, the world's most advanced solution, is adopted for the
trolleying mechanism and slewing mechanism, thus ensuring more
stable and reliable operation ;• The cab is independently installed
externally with good vision and large inner space, thus offering a
good working environment for operators;• A variety of safety
devices are equipped, which are all mechanical or mechatronic
products that are applicable to severe working conditions, so as to
ensure the tower crane's reliable operation.Notice:All models can
be customized according to customer needs./* March 10, 2023
