Product Description:

Assembly of the cabin
on the ground
Thanks to its rotating cabin, a single rotation
and quick locking is sufficient for
the whole assembly to be ready to mount
in just a few minute

Assembly
of the counter-jib
Connection is simplified by the used
of just 2 stepped pins for easy installation.

Comfort when driving
Vision Cab offering:
A panoramic windscreen (40% more visibility in  • 
relation to conventional cabins, downward visibility
and reduction of blind spots).
Thermostatically controlled heating.  • 
Ergonomically designed to reduce operator fatigue  • 
and so contribute to safety and productivity on work
sites.
The control and driving aids are enhanced   • 
with the latest innovation

Mechanisms
All Potain’s know-how has been devoted to productivity
and comfort while driving. Concentrated centrally,
the standard-fitted variable frequency mechanisms provide
better performance.

DVF mechanisms
The jib-foot DVF mechanism is easily accessible and
completely safe.
Progressive speed variation by proportionalcontrol.
The speed depends directly on the control input by
the crane operator.
To make driving the crane easier, 2 hard spots integrated
into the controls provide better selection of the desired speed.

LVF mechanism
With three mechanisms (25, 33 and 50 LVF Optima), the MDT City Cranes
are capable of high working speeds through optimising speed in accordance with
the load hoisted, allowing for gains in productivity.
• For the first increments (approach speed, sling tension, etc.) hoisting of the load
is controlled by the safety device (Dynamometric Ring).
• For working speeds, the Optima system adapts the speed in accordance with the
load hoisted. This enables full power of the engine to always be used for optimum
productivity.
The LVF Optima provides a gain of around 25% in lowering speed. For the technician there is a maintenance aid with display + keyboard incorporated
into the frequency convertor (providing auto-diagnostics, display of operating
parameters, defects, etc...).
The hoisting winch is factory pre-assembled.

RVF mechanism
The RVF Optima + slewing enables smooth movements.
Fully integrated progressive control.
Driving adapts to the behavior of the crane operator:
• Traditional driving thanks to action controlled
by stopping of the command. The slow-down phase
of the jib is managed by the frequency variator in this
case.
• Or by reverse command in the slow down phase called 
a “counter-slewing” command.
As a result, the crane operator can control stoppage
of the movement.

Installation and Maintenance
Ease of access and
greater safety.
Improved safety conditions for all persons
coming into contact with the crane.
Walk-way on the initial components of the jib,
enabling risk-free movements on the jib.
Safe, maintenance on platforms associated
with each mechanism.
Electrification
Whilst operating or transporting, the cables are integrated
and/or stored easily in the crane,
increasing the service life of the
electrical equipment and providing optimal conditions of
safety.
The trolley basket on the cabin
side provides total safety for
the technician who remains in
the crane operator’s field of vision.
Quick checking from the trolley
basket.
The design of the electric sockets allows
simple and quick
connection on all sites.

The Dialog Visu II unit is available as standard and displays on-screen all the indicators required to drive
the crane.
The Visu II display unit is an information terminal, which means that from the control console it is possible to view the parameters concerning:
- The position of the hook (height, range)
- The stresses on the machine (load, moment)
- Information on reeving
- Driving aids
- Defect codes
- Wind speed
AS AN OPTION, jib position and zone limitation are available.
Calculation of this information comes from
the processing unit via the BUS/CAN.

Q:What are the characteristics of a tower crane?
Two, according to the structure characteristics of the boom can be divided into the pitching amplitude boom (boom) and trolley jib tower crane (arms).Luffing jib tower crane luffing jib by lifting does not achieve the amplitude, the utility model can give full play to the effective height of the boom, simple mechanism.Trolley jib tower crane is installed on the level of the boom on the track trolley achieve amplitude, the utility model has the advantages of large amplitude range, trolley can near the tower, can load amplitude, the shortcoming is: the boom stress on the structure of complex, high requirements, and the boom and the car must be in the building the upper part of the spire, the installation height should be higher than the roof of buildings 15-20 meters.Three, according to the turret structure, the rotation mode can be divided into lower slewing (turret rotation) and upper slewing (turret not slewing) tower crane.Under the rotary tower crane slewing bearing, balance weight mechanism are arranged on the lower end of the main tower, its advantages are: less bending, low gravity, good stability, convenient installation and maintenance, the disadvantage is the higher requirement to the slewing bearing, installation height is limited.The slewing tower crane is characterized in that the slewing bearing is balanced and the main mechanisms are arranged at the upper end, and the advantage of the utility model is that the lower part of the tower body can be simplified, and the lifting and the adding of the joint can be simplified because the tower body is not turned. The disadvantage is: when the building exceeds the tower height, due to the influence of the balance arm, limit the slewing of the crane, at the same time, the center of gravity is higher, the air pressure increases, the weight increases, so that the total weight of the whole machine increases.
Q:Notice of tower crane
Installation condition of 3.2 tower crane3.2.1 tower crane has special equipment manufacturing license, product certification, manufacturing supervision and inspection certificate, the tower crane manufactured abroad should have product certification, and has been in the construction administrative departments for registration.3.2.2 tower cranes shall be of complete structure and conform to the provisions of GB5144 "safety regulations for tower cranes".3.2.3 under the following circumstances, tower cranes are not allowed to use:If the state has been eliminated from the designated period of time, exceeding the prescribed service life assessment, the safety devices and safety facilities can not meet the safety and technical standards of the state or industry; there is no complete safety technical file.3.2.4 tower cranes must be maintained and fully checked before they are installed. Structural parts with visible cracks, severe corrosion, overall or partial deformation, connecting shafts (pins), Kong You, severe wear and tear should be repaired or replaced, in accordance with the provisions of the installation.3.2.5 tower crane foundation should meet the requirements of the use manual, the carrying capacity of the foundation must meet the requirements of tower crane design, installation should be carried out before the hidden project acceptance, qualified before installation.

Q:Who invented the tower crane, please?
Tower crane originated in Western europe. The first patent on tower cranes for construction was issued in 1900. In 1905, a crane with a boom was fixed in the tower.
Q:How much height should tower crane work at M?
Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q:Where can I get the tower crane manufacturing permit?
This is the permit of the Bureau of quality supervision
Q:What does "jack up" tower crane 1000KNm mean?
The Greek letter of torque is tau. The concept of torque originates from Archimedes's study of leverage. Rotational torque, also known as torque or torque. The torque can change the rotational motion of an object. Pushing or pulling involves force, while torsion involves torque. The moment is equal to the cross product of the radial vector and the force.
Q:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
Q:Do self lifting tower cranes allow a small swing of the boom in jacking operation?
The upper working structure of the attached tower crane is connected with the jacking sleeve frame, and a jack jack is mounted on the top lifting jacket frame. The upper crossbeam of the jack is connected with the jacking frame, and the lower cross beam is provided with a movable claw, and the lower supporting point can fall on the step of the standard section of the tower body. During lifting, first trim jib and balance arm, unlock the top are connected with a lifting sleeve frame with the standard section, start lifting system, lifting jack will superstructure.
