Description
Technical field
Present application relates generally to gantry crane technical field, more particularly to the traction raising gate-type applied to port and pier
Crane.
Background technology
In recent years, with the expansion of China's Foreign Trade, Container Transport industry fast development, while having driven container dress
Unload the technological progress and fast development of equipment.Portal crane is compared with the various cranes that other industry is used, operating efficiency
Height, energy consumption is also universal very high, therefore realizes that the energy-conservation of container handling device and emission reduction meaning are very great.With energy prices
Lasting lifting and energy-saving and emission-reduction policy go deep into, the lightness and economy of container handling device will turn into one it is new
Development trend.
Traditional tyred container door type crane and rail-mounted gantry container crane are all container hargours
Important handling facilities, occupy leading position in modern port Container Yard, and the current whole world there are about the various rule of more than 7000 platforms
The tyred container door type crane of lattice accounts for the 90% of storage yard container handling facilities, in recent years rail mounted packaging in operation
Application of the case gantry crane in stockyard is also more and more extensive.They all have high operating efficiency, space availability ratio height, productivity ratio
High the characteristics of.But traditional tyred container door type crane and the lifting mechanism (steel of rail-mounted gantry container crane
Cord coiler device) and wheeling mechanism be all disposed within trolley frame so that the weight of dolly is big (up to 25 tons), so as to increase
The weight of complete machine is added, this kind equipment has the shortcomings of wheel load is big, cost is high, routine use maintenance cost high, energy resource consumption is big.
Container Transport to along the Changjiang river and inland river, it is interior develop during, various regions occur in that a large amount of medium and small collection
Container berth stockyard and terminal.For medium and small pier storage yard, if indiscriminately imitating coastal professional Container Yard completely
Technology pattern, will cause enterprise investment increase, economic benefit to decline.Many medium and small Container Yards face traditional wheel
Tire formula gantry container crane and rail-mounted gantry container crane, are all existed " cannot afford, Guan Buqi, can not afford "
Problem, and general crane gear is difficult to complete container handling, pile, the job requirement carried.Therefore, in the urgent need to one
The economical container handling device that all kinds of harbours are particularly medium and small container pier storage yard and terminal can be adapted to by planting.
Utility model content
In view of drawbacks described above of the prior art or deficiency, expect to provide a kind of traction raising gantry crane to solve
Not the problem of existing wheeled crane is not suitable for middle-size and small-size container pier storage yard, terminal.
The application, which provides to slide on a kind of traction raising gantry crane, including door frame, the crossbeam of the door frame, sets small
Car, the underhung of the dolly has suspender, and the door frame left lower is provided with two sets of wire rope roll winding apparatus, and two sets described
