Abstract
The utility model provides a multifunctional crawler-type folding-arm crane. The crane comprises a vehicle body, an engine, a large arm and a two-section arm, wherein a three-section arm is arranged on the front part of the two-section arm; the three-section arm can be controlled by an oil cylinder in the two-section arm to retreat into the two-section arm; a detachable carrying lever and a lifting hook are arranged on the front part of the three-section arm; the carrying lever is controlled by a carrying lever oil cylinder arranged below the carrying lever; and the carrying lever oil cylinder is connected with the engine via a pipeline. The multifunctional crawler-type folding-arm crane provided by the utility model has the beneficial that the telescopic-arm type full-hydraulic crawler-type lower cabin crane aims at providing a special tool for a lower cabin craning operation. By adopting a craning arm with a telescopic bending arm and applying the core technologies of a mature excavator hydraulic system and the like, the multifunctional crawler-type folding-arm crane has the advantages of the traditional loading-unloading machinery, and further has the advantages of being stronger in adaptability to site space, stronger in bearing capacity, low in maintenance cost, short in auxiliary working time, high in operating efficiency, energy-saving and the like.
Description
Technical field
The utility model relates to a kind of hoisting crane, particularly a kind of multifunction retractable crawler crane of cranking arm.
Background technology
At present, the port and pier loading and unloading need a large amount of lower cabins mechanical work to cooperate the door machine operation, but working space is little under the cabin, highly low, and traditional hanging device, such as fork truck, wheel-mounted crane, excavating machine etc., although can solve the needs of producing, but the limitation of the goods class of the loading and unloading that can bear in the operation of lower storehouse is very large, and efficient is lower, and the restriction in space also greatly affects the performance of these equipment performances.This certainly will have influence on the whole running efficiency at harbour, and cargo mass, safety in production are all brought certain impact.
Cabin hoisting crane under the present telescopic boom all hydraulic caterpillar has solved the work pattern of time cabin machinery, and it is narrow and small that this machinery has satisfied working space, short working condition requirement, be applicable in the present all kinds of dry cargo hold handling, pile high job requirements.The cabin hoisting crane is compared with machineries such as traditional fork truck, loader, excavating machines under this kind telescopic boom all hydraulic caterpillar, has larger advantage in the operation of lower storehouse.
Summary of the invention
For structural deficiency in the prior art, the purpose of this utility model provides a kind of multifunction retractable crawler crane of cranking arm, and is beneficial to reach that to satisfy working space narrow and small, under the operating mode of short condition, and the function of efficient hoisting operation.
For achieving the above object, the technical solution adopted in the utility model provides a kind of multifunction caterpillar arm-folding crane, this hoisting crane includes car body, driving engine, large arm, two joint arms, the hydraulic control system that links to each other with driving engine, wherein: described two joint arm front portions are provided with three joint arms, described three joint arms are controlled at stretching in the two joint arms by the oil cylinder that is arranged in the two joint arms, described three joint arm front portions are provided with detouchable and choose thick stick and suspension hook, the described thick stick of choosing is controlled by being located at the thick stick oil cylinder of choosing of choosing the thick stick below, and chooses the thick stick oil cylinder and be arranged on the interior oil cylinder of two joint arms all to be connected with hydraulic control system.
Effect of the present utility model is the special tool that the purpose of cabin hoisting crane under this telescopic boom all hydraulic caterpillar provides a kind of lower cabin hoisting operation.Adopt crank arm telescopic formula crane arm, use the ripe core technologies such as excavator hydraulic system, make this machine except the advantage with traditional loading-unload machine, also have to the comformability in space, place than stronger, load-carrying capacity is larger, maintenance cost is low, service working time is short, operating efficiency is high and the advantage such as energy-conservation.
