Fork handle, lowering or hoisting gear and propulsion plant, only depict how yoke part is injected below goods, how to cooperate on the ground
The processes such as liter, decline, advance.In order to describe conveniently, four yokes from bottom to top by 1,2,3,4 numberings.1st, No. 3 are A yokes
Connection, 2, No. 4 be B yokes connection.Exemplified by pitching dress and carry casing type objects.
In Fig. 7, K-K vertical lines are the initials that four yokes are initially inserted into below casing.1,1, No. 3 yokes are in initial
Position is motionless.2nd, No. 4 yokes advance, and the wedge mouthful of yoke front end injects the gap pitched between lift casing and following object, inject
A bit.Then lifted a bit on this two yokes, pry open some gaps of expansion, remain stationary as.In 2, Fig. 8,1, before No. 3 yoke horse backs
Enter, it is more extending deeper in the gap that front end wedge mouthful insertion is pried open.Then the appropriate height of upper lift, is remained stationary as.In 3, Fig. 9,
2nd, No. 4 yokes advance at once, in front of whole yoke below insertion casing, and appropriate upper lift a bit, lifts bottom, reserve 1, No. 3 forks
Arm has appropriate decline space, remains stationary as.Procedure below is, every group of yoke alternately decline a little to setting height, proceed to and set
Set a distance, rise to setting height and lift casing, until being inserted through below whole casing.I.e. liftable tote box body.Yoke is injected
To not rubbed below casing during below casing.
During unloading, appropriate height above put position is transported in casing lift, the bigeminy yoke of each yoke group is alternately lifted
Casing, alternately decline, retrogressing, until casing puts off placement location.
Often rising, the decline of connection yoke is that the lowering or hoisting gear connected by fork handle is completed.Often connection yoke advance, after
Move back, be that the propulsion plant connected by fork handle is completed.
Insert and start two to three times in the following a small amount of gap of casing at first in yoke, manual control operation can be used, pressed later
Lower autokeyer, the overall process that yoke is inserted below whole casing, all by automatic control system by programme-control hoist cylinder,
The whole do actions of propelling cylinder control yoke.Yoke group is inserted through the required stroke of goods, and startup is being automatically controlled by operator

Top fork carries away several bags directly from the bag cargo of pile, and the situation of the direct pile of another placement location can be transported to again
Figure.
During yoke insertion goods 18 is following, if propelling cylinder alternates propulsion, fork handle is driven before yoke
Enter, it is following until being inserted through goods.Telescopic arm forklift is motionless in itself.Thus cause propulsion slide plate long, propelling cylinder
It is long.Therefore it can be manufactured by two kinds of structures.One kind is to promote Lengthened slide plate type, and one kind is to promote slide plate plain edition.Lengthen
Type promotes slide plate to be to lengthen to promote the peaceful balladeur train of slide plate, propelling cylinder, and can disposably providing yoke, to be inserted through goods following
Advance distance, telescopic arm forklift is motionless.The propulsion plant and yoke total length installed on this telescopic arm forklift, still can be with
No more than original mechanism of telescopic handler length.Because fork dress bag cargo and casing class, combination yoke is not long in itself, deficiency is existing
There is the half of mechanism of telescopic handler long.Another structure is to promote slide plate plain edition, promotes slide plate not lengthen.When propulsion slide plate
When being run low with propelling cylinder stroke, driver obtains signal, the segment distance that advances of driving, and yoke is motionless.Telescopic arm forklift
Before advance, the oil pipe on propelling cylinder inner carrier both sides is all communicated with oil extraction case, i.e., it is identical with atmospheric pressure.Telescopic arm forklift advances
The oil of right section of oil cylinder is discharged into oil extraction case by middle push piston bar.Dropped under yoke on following goods or ground, goods on yoke
Weight is pressed on yoke, and the resistance that yoke advances is very big, it is impossible to advance.Smooth frame is with promoting the frictional resistance of slide plate inherently very
It is small, so only smooth frame can be slided.So, when telescopic arm forklift advances, yoke is motionless.During the multiple intermittent of yoke is promoted
Pushing plate this segment distance is left to be eliminated.Yoke can restart to promote.Telescopic arm forklift movement is promoted, in 1 to 3 underrange
Just.This structure, it is possible to reduce the length of propulsion plant.
The corresponding joystick of increase, button, keyboard, the circuit to control combination yoke in telescopic arm forklift driver's cabin
And oil circuit.Control system is to control and automatically control the control mode being combined manually.
It is provided with camera, accompanying drawing and is not drawn into front of vertical balladeur train.Driver is set to observe telescopic arm forklift front end goods
Thing gap situation, is easy to yoke accurately to inject gap.
