The usefulness of technique scheme is:

The utility model device is by himself its specific structure design, that is: mount the chute that connects on the framework as inclusion body with the fork of forklift truck frame, and with about the outside slide bar that links of pallet fork as by the sliding motion pair of inclusion body, under the driving of fork truck hydraulic oil, a pair of oil cylinder produce flexible crank motion and drive a pair of about outside pallet fork withdraw in opposite directions, or oppositely open action, respectively with about the spring cylinder that links of inboard pallet fork under the cooperation of framework center line retraction elastic force, realize in outward left+left side, right outer+right in pallet fork hold together to close or separated position, promptly correspond respectively to fork and hold one, about the state of two pallets.

The distinctive C shape of framework chute, T shape slide bar section bar, system adopts the high-strength alloy material, realized general frame, the high strength of element unanimities such as sliding pair, when rigidity is superior, provide the forklift operator person to see through the visual field permeability of framework to greatest extent, significantly improved operating efficiency, reduce the breakage rate, hold ground pallet cargo no matter be at fork, or, fork truck holds second when giving rise to certain altitude fork, during the 3rd layer of goods, truck driver all can see through the form of reserving in the framework and observe goods, accomplish that pallet fork contraposition quickly and accurately and fork hold, avoid damage goods.

The high strength framework possesses good rigidity, cooperate exclusive total length clad type sliding bearing, fully having guaranteed to open outside pallet fork can be not excessive and sagging because of gap, the distortion of cantalever element stand under load excessive between the secondary dynamic and static element of sliding motion when exceeding frame width, one-tenth cantilevered load state; In addition, about outside pallet fork with respect to about inboard pallet fork be provided with specially that trace is high to be risen.The resultant effect of these factors is promptly: pallet cargo can not turn up to the left and right and cause dropping of goods about having avoided opening at pallet fork, pitched when holding 2 pallets, has realized safe safe, high efficient and convenient operation.

By the control of hydraulic valve, separate/holding together to close action and all carrying out synchronously of left and right sides pallet fork guaranteed the accuracy of operation, reduced the damage to pallet and goods, improves transport operation efficient.
