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.

Reduced assembly time 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 counter-jib ties are fitted with tie supports, thus avoiding the use of wooden jacks. The cabin-mast is spliced on the pivot using 8 pins.

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 speed and the maximum speed are adapted to the weight of the load. In orientation, there is controlled proportional speed 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. A moveable pulley can be used without maintenance on the cat...

DVF Distribution The jib-foot DVF 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 controls provide better pinpointing of the speed.

LVF Hoisting 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. • or the first increments (approach speed, sling tension, F etc.) hoisting of the load is controlled by the load security device (a proving ring). • or working speeds, the Optima system adapts the speed in F 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...

Maintenance and safety For easier, safer and quicker maintenance. Platforms and walk-ways for access to all mechanisms. The cabin is on the same side as the trolley basket. For the technician: there is a maintenance aid with display + keyboard incorporated into the frequency variator console (providing auto-diagnostics, display of operating parameters, defects, etc.). The MDT range boasts devices that enable usage in total safety. All the movements are supervised by range limiters with slowing before stoppage. The maximum load is monitored by a proving ring located in the cat head. Range...

The design of the electric sockets allows simple and quick connection on 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. • ere is a special channel for electric Th wiring in the counter-jib.
