Product Description:

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.

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.

Q:How do you make one of those paper cranes?
Here are some links to pages that show you how to make the crane. You might also like to look for some general Origami pages, they will help you understand the directions if you run into a problem. Sometimes in origami you need to make a fold and then unfold it - the crease that was created by the un-fold will be used later - the instructions for this type of fold can be confusing. The first link is a step by step instruction site for the crane - very good illustrations with instructions accompanying each photo - it spans multiple pages so you need to click the next button at the bottom of the page as you finish each set of instructions. The second link is a full view of drawings of each fold on one single page - the instructions aren't as detailed, but it does give you the opportunity to see how each fold is supposed to look in one view. The third link is a link to a japanese site that explains the significance and history of the crane and what it means - it's very interesting. Good luck.
Q:How heavy does a crane need to be to lift 5 tonnes?
If the crane HAS a 5-ton capacity, then to be able to estimate the weight you would need to know the length of its lifting arm at maximum extension w.r.t the C.G. of the body of the crane. So suppose we have an arm length of (say) 6 mtrs, then the max turning moment at the fulcrum (from front wheels of crane ? ) due to the Load alone = 5 x 6 = 30 You need to add the moment for the arm itself. Lets say the arm is around 1/2 ton. And its c.g. is approx 1/3 the distance from the fulcrum. Then this adds another = 1/2 * 1/3 *6 = 1 So total moment is 30 + 1 = 31 The body of the crane must be MORE than this. Suppose the C.G. of the crane is 2 meters behind the same fulcrum. Then weight of the body must be 31/ 2 = 15.5 tons. Lets say the weight is 16 tons. Then the TOTAL mobile cranes weight would be 16 (body) + 1/2 (arm) ~ 16.5 tons It all depends on the dimensions of the crane, and where the c.g. is located. If the crane has ballast added right at the back, then it's overall weight can be made less since it's c.g. would get shifted further away from the fulcrum
Q:Was Lana Turner's husband, Stephen Crane, the author of Maggie: A Girl of the Streets?
hah ha i'm in your class too :) This project sucks... and I still haven't done it! I have to tonight..
Q:Boston Legal: Denny Crane Question!?
It's just you, you poor thing.
Q:analysis of jib crane?
I would suggest that you delete this question and submit a new question with enough details for someone to give you an answer. This is not a question I can give you much help on
Q:Do cranes, the bird, have any significance in Egyptian or Chinese mythology?
A crane is considered auspicious in China. It is one of the symbols of longevity and is often represented with other symbols of long life, such as pine, bamboo, and the tortoise. Also, traditional Chinese 'heavenly cranes' (tian-he) or 'blessed cranes' (xian-he) were messengers of wisdom. Legendary Taoist sages were transported between heavenly worlds on the backs of cranes.
Q:More than meters of tower cranes must be equipped with red barrier lights at the top
To see the land of tower crane or floating crane... Basically,
Q:Is it safe to lift a heavy load using three crawler crane for the purpose to rotate the item?
This is strictly a question for an experienced rigging contractor. There is a lot more to the question than just what cranes you are using. I have been involved in the lifting of many large vessels up to 150 foot in length and over 600,000 lbs. If you have to ask questions like the above, you have no business even involved in such a project. There are many contractors who are experienced in doing the kind of work you are asking about. I would not undertake such a job without some very experienced folks taking the lead.
Q:Cranes or storks?
Depends on where you live ? Stick to Ornamental Pheasants or Ducks,Storks and Cranes,need to be penned in at night because you will have to pinion them to prevent them flying. Try some Golden Pheasants for a try ,Lady Amherst are becoming a rare commodity and are quite expensive,if you have Foxes and Mink,then no matter what you get you will have problems these two predators.
Q:Can the attached arm of the tower crane be welded?
The calculation of the attachment of tower crane mainly includes three parts: attachment rod calculation, connection calculation of attached bearing and calculation of attached frame. (1) the attachment bar calculates the attachment bar and is calculated by the compression member of the pivot shaft hinged at both ends. 1) the internal forces of the attached rod and the internal force of the connecting rod are taken as required by the instruction; if the specification does not specify, or when the spacing between the two supports connected with the building is changed, the calculation shall be carried out.
