Abstract

A flexible and adjustable lifting appliance of a forklift solves the problems that the existing forklift lifting appliance is restrained in sling height and inconvenient to use, and comprises a lifting hook, a supporting arm, a supporting seat and a base which is fixed at the lower part of the supporting seat. The lifting appliance is characterized in that the supporting arm is hinged on the supporting seat; a supporting hydraulic cylinder is installed between the supporting arm and the supporting seat; a flexible arm is arranged at the front end of the supporting arm; a flexible hydraulic cylinder is arranged between the flexible arm and the supporting arm; and the lifting hook is arranged at the front end of the flexible arm. The lifting appliance has the advantages that by installing the flexible arm at the front end of the supporting arm, the lifting arm can stretch out and draw back; by adopting the flexible hydraulic cylinder, the length of the lifting arm can be adjusted, so that the lifting appliance can lift goods at longer distance; as the supporting arm is hinged with the supporting seat, the angle of the lifting arm can be adjusted, so that the goods can be lifted higher; and the overall height of lifting the goods is equal to the sum of the lifting height of a sliding frame of the forklift and the steeving height of the lifting arm, so that the forklift can be used as a mobile crane, therefore, the functions of the forklift are expanded, and the forklift is more convenient to use.

Description

The adjustable length forklift slings

Technical field

The utility model belongs to a kind of hanging device, particularly a kind of adjustable length forklift slings that is suitable for the fork truck use.

Background technology

Fork truck is a kind of mechanical equipment of handling goods, is extensive use of in production field.Along with industrial development, appearance much is not suitable for the goods with the fork truck loading and unloading, as container class, parcel class and bag class goods etc.In order to lift this class goods, expand the function of fork truck simultaneously, realize the many usefulness of a car, people have designed forklift slings, are used for lifting the goods that this class is not suitable for the fork truck loading and unloading.Existing forklift slings mainly is made of suspension hook, hold-down arm, supporting seat and base etc., and hold-down arm is horizontally disposed with, and supporting seat vertically is provided with, and is rigidly connected between the two, and suspension hook is installed in the front end of hold-down arm, and base is fixed on the bottom of supporting seat.During use, the pallet fork of fork truck is removed, base is installed on the sliding rack of forklift door frame, promptly can be used to lift goods.The subject matter that this forklift slings exists is that hold-down arm can not extend, and can not shorten, can't adjusting angle, can only be along with the sliding rack on the forklift door frame upper and lower moving, therefore, the height-limited system of lifting is used inconvenience, is difficult to satisfy the requirement of lifting goods.

Summary of the invention

The technical problems to be solved in the utility model is, overcomes restricted, the inconvenient problem with use of sling height that existing forklift slings exists, and a kind of arm flexible, whole, the easy to use adjustable length forklift slings of adjustable angle are provided.

The utility model comprises suspension hook, hold-down arm, supporting seat and base, base is fixed on the bottom of supporting seat, its special character is, described hold-down arm is hinged on the supporting seat, between hold-down arm and supporting seat, supporting cylinder is housed, front end at hold-down arm is equipped with telescopic boom, between telescopic boom and hold-down arm telescopic hydraulic cylinder is housed, and suspension hook is installed in the front end of telescopic boom.

Advantage of the present utility model is, front end at hold-down arm is installed telescopic boom, and between is provided with telescopic hydraulic cylinder, realized the flexible of arm, utilize telescopic hydraulic cylinder can adjust the length of arm, the farther goods of can slinging, hold-down arm and supporting seat is hinged, and supporting cylinder is set, realized the adjustment of boom angle, goods can hang De Genggao, the bottom-to-top-height of slinging be fork truck sliding rack lifting altitude and arm steeve the height sum, make fork truck become a jenny, expanded the functions of use of fork truck, satisfied different handling requirements, and used convenient.
