Product Description:

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.

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).

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.

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.

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.

Q:in the karate kid 1984 is the crane kick something they just put in the movie and not real ?
The Crane kick is an actual Martial Arts move it is done in some Hung Ga Kung Fu forms but differently than the one in the movie because it is done without jumping and is much faster the crane kick in the Karate Kid is just a figment of the director and screen writers imaginations.
Q:why should i look forward to reading stephen crane?
Well, you know he lived in the late 1800s, so you probably have an idea of what his poetry will sound like. Then you read some of it, and the effect is sort of like walking into what you think is going to be a prissy hair salon and being whacked over the head with a bunch of bananas wielded by a glow-in-the-dark green monkey from Jupiter. Crane's stuff is that weird. And I mean that in a good way.
Q:what are the forces in a cantilever crane?
forces for cranes are dynamic , so u'll have repeated cycles of compression tension ( i assume it's a trussed crane). but generaly for a cantilever , the main forces are -ve Bending Moment +ve shear which changes the rft. bars position if dealing with R.Concrete for example
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:do cranes have any symbolic purpose?
Cranes Symbolism
Q:What are the safety devices in a tower crane?
Moment limiting torqueWeight limit; weight LimitedThe car looks for car restrictions limitFrom the ceiling to prevent hoistingThe slewing limit is limited to Slewing
Q:Is their a difference between a flamingos and cranes birds?
Yes quite some difference,Flamingos are crustacean feeders brine shrimp and similar, feeding by sifting water through their bills by a pumping action and feed in water.Their habitat is Tropical climbs Cranes on the other hand are mainly land or swamp birds feeding on Frogs Lizards even snakes and other insects., they live in various regions even in cold areas. This is only a brief description so I hope it has helped
Q:How do I build a Hydraulic crane using the following items?
build a basic crane out of your materials and thread the string to the magnet hold it on with tape secure opposite end of the string to the plunger on one syringe. and fix this syringe(syringe 1) to the frame of the crane. position the plungers of both syringes at mid point, and fill both with water, and fill your tubing with water. connect the needle ends of both syringes together with the tubing. pushing the plunger on syringe 2 will cause the plunger in syringe 1 to move out. pulling the plunger on syringe 2 will cause the plunger on syringe 1 to retract and can be used to lift the paperclip.
Q:I have to do some research on a crane and technology itself (please help me)?
Q:Where can i buy a claw/crane machine that you see in pizza parlors and arcades?
You can buy that stuff at gamig stores that sells alot of gaming equipment
