Excellent Performance & Strong Engineering Adaptability
MDG series gantry cranes are specially developed for the use of hydropower, thermal power construction and other user equipment needs to be frequently disassembled and installed, often long-distance transfer and transportation, the first time into the plant without a large mobile crane, the use of the changing environment and other use characteristics of the new crane. The machine has the advantages of small wind area, strong wind resistance, wide operating range, large speed range, high efficiency, advanced configuration, light weight, easy to install and dismantle, low transportation costs.


Modular Design Fast Disassembly & Low Transportation Costs
Modular advanced design concept ensures convenient disassembly and assembly of MDG series gantry cranes, luffing mechanism and hoisting mechanism have been installed in the steel leg section of the bridge frame before leaving the site, which greatly reduces the transportation size; running mechanism, driver's room, electrical room and other modules are highly integrated, and each accessory has been installed before leaving the site, which reduces the on-site disassembling and assembling work to the greatest extent possible. With the reasonably optimized distribution scheme, only 4 sets of plate trucks are needed to complete the long-distance transfer of the whole vehicle, saving transportation and dismantling costs for customers to the maximum extent.


Strong Wind Resistance & High Wind Safety
The main structure of main girder, rigid leg, flexible leg and other main structures are tube truss structure, small wind area, strong wind resistance, with multiple windproof devices such as rail clamps, cable wind rope, iron shoes, etc., It can withstand class 12 wind in non-working condition, which can effectively guarantee the safety of the equipment.


Verified By Domestic And Foreign Engineering & Reliable Quality
MDG series gantry cranes have been put into use for nearly one hundred units so far, and have been verified by the project to be of reliable quality and good performance, and have been exported to overseas countries. It has created good economic benefits for customers and has been highly praised by users.
