Description
Technical field
The utility model belongs to the loading-unload machine field, relates to fork truck, specifically, is the special-purpose arm of a kind of fork truck.
Background technology
Fork truck has another name called forklift, is a kind of loading-unload machine, and it is made up of car body, pallet fork, crane, door frame etc., be mainly used in the handling of goods, but the pallet fork of fork truck can only promote goods, can not lift goods.For this reason, notification number is CN201553586, the Chinese patent that name is called " a kind of fork truck auxiliary boom " discloses a kind of fork truck boom structure, comprise support and cantilever, the base of support by a pair of vertical arrangement be parallel to each other and the cross section is that rectangular steel pipe constitutes, the top, horizontal of support is provided with the cantilever that stretches out support, and the end of cantilever is welded with suspension ring.The fork truck auxiliary boom of this kind structure has significant disadvantages: labor is as follows:
First, support is made up of four pillars, its left front, left back pillar is arranged by isosceles trapezoid, right front, right back pillar is also arranged by isosceles trapezoid, the shortcoming of this arrangement is: the front and back width of support is too big, the level of cantilever in addition, the space of cantilever below is too narrow and small, is unfavorable for goods is hung charge and discharge operations.
Second, left front, the right front pillar of support is arranged by isosceles trapezoid, left back, right back pillar is also arranged by isosceles trapezoid, the shortcoming of this arrangement is: the left and right width of support is too big, it is too many to take the and arranged on left and right sides space, and when pallet fork was mobile to the left or to the right, support was run into personnel and the goods that is positioned at both sides easily, dangerous, also overslaugh driver's seat.
The 3rd, cantilever and support are welded into a whole, and volume is big, and heavy, can't decompose dismounting fast, are unfavorable for the fork truck translation function, become to promote the goods function from lifting goods functional shift.
The 4th, suspension ring are welded on the end of cantilever, suspension ring can not carry out forward and backward adjustment along the direction of stretching out of cantilever, also just can't change the center of gravity of the relative fork truck of goods, though the fork truck maneuverability, its wheel base is shorter, if lift very heavy goods, the center of gravity of goods is very forward again, and then fork truck leans forward easily, lack of equilibrium.
The 5th, bracket base on the pallet fork of fork truck, does not have safety device by the band steel pipe box, pallet fork lifting and tilting forward and back in the process, and bracket base comes off from the pallet fork of fork truck easily, and it is bigger to draw trouble safely.
The utility model content
For addressing the above problem, the purpose of this utility model provides the special-purpose arm of a kind of fork truck, is installed on the pallet fork of fork truck, with the supporting use of fork truck, make fork truck have the function of lifting goods, enlarged the loading and unloading scope of fork truck, and it is big to hang the charge and discharge operations space, be not easy to meet personnel and goods, also not overslaugh driver's seat can decompose dismounting fast, be beneficial to the fork truck translation function, the center of gravity of goods can be adjusted, and is provided with safety rope, and the accident of having eliminated is drawn trouble.
