True crawl, crawl securely, grab high-efficient, saving manpower.
The object of the present invention is achieved like this: a kind of large-scale crane, including horizontal support and longitudinal carrier, the longitudinal direction
Bracket is separately positioned on the two sides of horizontal support, and respectively left support and right support, the lower section of the left support and right support
It is provided with idler wheel, the idler wheel is divided into left wheel and right idler wheel, and being arranged side by side before and after the left support and right support there are two groups；Institute
It states and is provided with ladder on left support or right support, the ladder continues up to the top of horizontal support from idler wheel；The cross
Include preceding horizontal support and rear horizontal support to bracket, is provided with loop wheel machine between the preceding horizontal support and rear horizontal support, institute
It states loop wheel machine and is provided with track between preceding horizontal support, rear horizontal support respectively；It is provided with below the loop wheel machine and hangs pawl, it is described
Pawl setting is hung there are four boom, each boom can move freely.
When the invention works, when the large-scale crane, when needing to lift by crane various containers, it is only necessary to by large-scale crane, pass through
Left wheel and right idler wheel, are moved to the underface of container, are moved to after underface, and collection is then grabbed by control loop wheel machine
Vanning, setting is there are four boom on loop wheel machine, a corner of each boom crawl container, container can very easily by
It picks up, due to being provided with reinforcing rib between left support and left support, so the large-scale crane can be good at keeping fastness, energy
Enough permanent uses, will not damage；When large-scale crane damage, the ladder of side setting can be convenient operator and climb up
Maintenance.
The beneficial effects of the present invention are, the large-scale container which can quickly prepare accurately is grabbed,
It is grabbed securely, grabs high-efficient, saving manpower.
As a further improvement of the present invention, to guarantee that the large-scale crane can be moved steadily；The left wheel packet
Include left front idler wheel and left back idler wheel；The right idler wheel includes right front wheel and right rear roller.
As a further improvement of the present invention, energy saving to guarantee that the loop wheel machine is mobile steady；The left front idler wheel and a left side
It is provided with driving mechanism between rear roller, is provided with driving mechanism between the right front wheel and right rear roller.
As a further improvement of the present invention, to guarantee that the large-scale crane can be good at being moved and its be braked；Institute
It states and is additionally provided with arrestment mechanism between left front idler wheel and left back idler wheel.
As a further improvement of the present invention, for guarantee the large-scale crane can for a long time it is sturdy and durable；The laterally branch
Frame is provided with reinforcing rib between left support and right support respectively.
As a further improvement of the present invention, to guarantee that device crawl is convenient, crawl is rapid；Four booms difference
By motor driven, the boom is symmetrical arranged.
Detailed description of the invention
Fig. 1 is main view of the invention.
Wherein, 1 horizontal support, 2 left supports, 3 loop wheel machines, 4 idler wheels, 5 right supports.
Specific embodiment
As shown in Figure 1, the object of the present invention is achieved like this: a kind of large-scale crane 3, including horizontal support 1 and longitudinal direction
Bracket, the longitudinal carrier are separately positioned on the two sides of horizontal support 1, and respectively left support 2 and right support 5, the left branch
The lower section of frame 2 and right support 5 is provided with idler wheel 4, and the idler wheel 4 divides for left wheel 4 and right idler wheel 4, the left support 2 and right branch
Being arranged side by side before and after frame 5 has two groups；Be provided with ladder on the left support 2 or right support 5, the ladder from idler wheel 4 always
It is extended to the top of horizontal support 1；The horizontal support 1 includes preceding horizontal support 1 and rear horizontal support 1, is laterally propped up before described
Loop wheel machine 3 is provided between frame 1 and rear horizontal support 1, the loop wheel machine 3 is set between preceding horizontal support 1, rear horizontal support 1 respectively
