Description
Technical field
The invention belongs to fork truck technical field is and in particular to the tackling system of reach truck.
Background technology
Reach truck is widely used in the industries such as Nicotiana tabacum L., food, weaving, electronics as a kind of important storage vehicle；
Particularly suitable in narrow opening with narrow shelf magazine operation.Requirement to reach truck is concentrated mainly on three in the market
Point: 1, the visual field is good, when that is, operator moves car stacking before use, is sitting in and can observe goods and shelf on driver seat
Relative position；2nd, while realizing high raising, i.e. stacking on the high shelf of more than 10m, and require maximum lifting height to increase,
The bearing capacity of fork truck reduces seldom；3rd, high stability, that is, goods lean forward and during hypsokinesis in high shelf stacking, car load rocks little.
At present, the three-level of reach truck staggers before and after the gantry channel-steel of free tackling system entirely or left and right is arranged in juxtaposition,
Exist door frame longitudinal direction total thickness c be more than 210mm, the carrying making goods away from forward so that lifting capacity is low；Laterally beam overall b is more than
169mm, outer mast beam overall a is not more than 690mm, along with fluid pressure line arrangement is not overlapping, so that the neutral gear in the middle of door frame is little, depending on
Wild poor；And three-level tackling system mostly is door frame angled manner, that is, goods tilts forward and back together with door frame, tilts gross weight greatly, whole
Car rocks also greatly, and dump ram is arranged on outer mast lower end, and dump ram stress is big.
On the other hand, at present, the side shifter of domestic front loading type forklift gantry configuration mostly is single sideward sliding function it is impossible to realize
Tilt function, malfunction, have impact on the effective utilization of reach truck to a great extent.
