Fitted with jib lengths ranging from 55 to 65 m, the MDT Topless cranes
boast hoisting capacities of 6 to 10 t.
Providing a suitable size for all your needs.
They allow complex multi-crane installations by considerablyreducing the
height gaps and interference of cranes on work sites.
The assembly, erection, transport and even maintenance times are reduced,
and as a result this helps to keep operating costs low.
Optimum productivity and greater safety make MDT Topless cranes the
best alternative for all users or hirers.
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
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.
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
• 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.
The construction hoist product produced by Fangyuan has achieved internationally advanced level in terms of industrial design, control and the drive performance, as well as the operation safety and comfortableness. And Fangyuan is also making efforts to keep improving the product, as what the construction hoist lifts is not only people and material, but also a kind of social responsibility and service concept…
The new generation SC series of construction hoists adopt modular structure, ergonomic design and advanced manufacturing technology, thus the adaptability and reliability of the product is greatly improved, e.g. the max. lifting height can reach 300 meters. The product adopts multiple patented technologies, reaches advanced level in China, and the market share in domestic market is increasing year by year. The product has also been exported to overseas countries like Russia, Turkmenstan, Vietnam, etc. winning the confidence of customers of both home and abroad
