Product Description:

Technical characteristics
•  Jib lengths of between 30 m and 80 m, per 5 m section.
•  Max. load of 10 to 40 t.
•  Hoisting power ranging from between 50 and 150 horsepower.
•  The masts used are K400 (1.6 m), K600 (2 m), K800 (2.45 m) and K850 (2.45 m, reinforced).

All the components of the MD range are designed to minimize the total number of trucksrequired to transport them between sites.

The jib components can house the jib tiesto make transport easier and quicker.

Thanks to the factory-performed pre-reeving and the auxiliary winch supplied as standard, assembly of the jib and counter-jib ties can be carried out quickly and in total safety.

The mechanisms are always used at full power. When hoisting, the speed is optimized according to the load and command used. In distribution, progressive variation of speedand the maximum speed are adapted to the weight of the load. In orientation, there is controlled proportionalspeed with optimal acceleration and deceleration in accordance
with the maximum admissible torque for the mast.
The auxiliary winch can be used on the derrick: this provides users with the possibility of a motorized derrick at the base of the machine.

DVF Distribution
The jib-footDVF mechanism is easily accessible in total safety.
Progressive speed variation by proportional control.
The speed depends directly on the controls manipulated by the crane operator.
To make driving the crane easier, 2 hard spots integrated into the controlsprovide better pinpointing of the speed.

With different mechanisms (33 to 150 LVF Optima or 108 to 215 hp LBR), MD cranes are capable of high working speeds through optimizing 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 load security
device (a proving ring).
•  For working speeds, the Optima system adapts the speed in accordance with the load hoisted. This enables full power of the motor to always be used for optimum productivity.
The LVF Optima provides a gain of around 25% in descending speed.

RVF + orientation
The RVF Optima + orientation enables gentle rotating movements without jerking.
Fully integrated progressive control.
Driving adapts to the behavior of the crane operator:
•  Traditional driving thanks to action controlled by stoppage of the command. The slow-down phase of the jib is managed by the frequency variator in this case.
•  Or by an inverted command in the slow-down phase, called a «counter-orientation» command.
As a result, the crane operator can control stoppage.

The design of the electric sockets allows simple and quick connectionon all sites.
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.
•  There is a special channel for electric wiring in the counter-jib.

Considered to be the parent range to tower cranes,
MD cranes have been around since the beginnings of the Potain brand. This range is the pillar of all Potain product know-how.
Constantly evolving to meet market expectations, these cranes are equipped with the latest technological innovations and boast the best performance possible.

Q:hey i have to submit this information about siberian cranes..please help me out....?
This species breeds in arctic Russia in Yakutia and western Siberia. It is a long distance migrant. The eastern population winters on the Yangtze River in China, the central population at Keoladeo National Park, India and the western population in Fereidoonkenar and Esfahan in Iran. It breeds and winters in wetlands, where it feeds on the shoots, roots and tubers of aquatic plants. This is a large white crane. Large males can exceed 140 cm (55 inches) in length and weigh over 10 kg (22 lbs). Adults are all white, except for a dark red mask extending from the bill to behind the eye. It has a yellow iris and reddish legs. The male is slightly larger than the female. Juveniles have a feathered mask and buff or cinnamon plumage. The voice is flute-like and musical. The status of this crane is critical, as it is expected to undergo a rapid population decline in the near future. The wintering site in China holding 95% of the population is threatened by hydrological changes caused by the Three Gorges Dam. Historic records from India suggest that a number of them wintered there in the past. This number has steadily declined and the birds are no longer found there. Mr. Rutledge of Entally told me that for twenty years he tried unsuccessfully to get live specimens of this crane, but did not succeed till a few years ago, when he and one of the native dealers got so many that the market was quite glutted, and many were sent to Europe. Since then the bird got scarce again, so this was evidently only a temporary invasion. —Frank Finn, Frank Finn in How to know the Indian waders. 1906 The Siberian Crane is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies and is subject of a Memorandum of Understanding concluded under the Bonn Convention. =]
Q:Under what circumstances does a tower crane require third party testing?
New clothes, relocation or transformation should be examined by the quality and Technical Supervision Bureau
Q:How to understand a Mobile Crane Load Chart?
Hello, Briefly, the structure of the crane or lifting mechanism is not usually the limiting case. The limiting case is to ensure that the Center of Gravity of the mobile crane with the load is such that it is bound within the tires or footprint of the crane. If this load is outside the footprint, the crane tips over.

Q:In the Hunger Games (book two) who is Seneca Crane?
Q:I need help on finding the least amount of steps on how to make an oragami crane.?
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
Q:how to do tower crane maintenance?
Q:airsoft gun crane stock to full stock switcharoo?
Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!
