Abstract

The utility model relates to a miniature crawler type tray crane, which comprises a crawler type base plate, a rotary platform, a slide moving weight balancing device, a crane arm support frame, a crane arm, a steel wire rope, a hanging hook and a motive power device, wherein two telescopic support legs vertical to a rubber crawler are respectively arranged at the front end and the back end of the base plate, a dozer blade is fixedly arranged on the front telescopic support leg, a folding tray is arranged at the front end of the rotary platform, the back end of the crane arm is hinged with the upper end of the crane support frame, and the lower end of the crane support frame is fixedly arranged on the rotary platform. The crane provided by the utility model can be used for realizing the safe hoisting and transfer operation in places incapable of being reached by large and medium-sized crane equipment, the soil pushing and ground leveling functions are realized, the loading, unloading and transportation functions are also realized, and the miniature crawler type tray crane is particularly suitable for the operation in narrow and small space or wet land, slope land and soft soil foundation environment.

Description

Miniature crawler type pallet jack

Technical field:

The utility model relates to the hoisting crane technology, specifically, is a kind ofly to have soil-shifting, lifting, transportation function and be applicable to small space or the minor crane of the soft soil foundation operation that some operating modes are more special.

Background technology:

Crawler crane is widely used in storing in a warehouse, the place of building ground, goods station and other items fortune dress.The traditional crawler-type hoisting crane mainly is made up of crawler-type traveling chassis, turn table, counter weight device, crane arm, steel rope, suspension hook and engine installation.Turn table is positioned at the top of cterpillar drive; Turn table is fixed on the chassis and can rotates freely; Counter weight device is positioned at the rear portion of turn table; The lower end of crane arm is hinged on the turn table, and the other end of crane arm is equipped with wire sling, and the lower end of wire sling is with suspension hook.Traditional crawler-type crane locomotive volume is big and heavy, is not suitable for operation in comparatively narrow space, more can not be poor at geologic condition, and like operation under the condition of wetland, hillside fields, soft soil foundation.

Summary of the invention:

The purpose of the utility model is; Overcome the deficiency of traditional crawler crane; A kind of existing soil-shifting, loading and unloading function are provided, transportation function is arranged again, and can on narrow space, soft foundation, carry out the Multifunction hoisting crane-miniature crawler type pallet jack of lifting operation.

The utility model is achieved in that

This miniature crawler type pallet jack mainly contains caterpillar chassis, turn table, slippage counter weight device, crane arm, steel rope, suspension hook and engine installation.Respectively there are two telescopic outriggers perpendicular to rubber belt track rear and front end on the chassis; Telescopic outrigger is fixed on the leg link, and the other end of leg link is hinged on the chassis, and two supporting legs can stretch out respectively or withdraw under engine installation drives to the left and right, are fixed with dozer on the telescopic outrigger in its place ahead; End is connected with tray fold before the turn table, flexibly connects through folding shaft between tray fold and the turn table; The rear end of crane arm and the upper end of lifting bracket are hinged, and the lower end of lifting bracket is fixed on the turn table.

Said slippage counter weight device can move forward and backward along track through engine installation, the stability when working to regulate hoisting crane.

During the utility model work:

When carrying out lifting operation, the supporting leg of the rear and front end on chassis all stretches out under the engine installation effect, is supported on the ground in operation place, adjusts the slippage counter weight device simultaneously, the stability of car body during with the assurance lifting;

When needs transhipment object, if the lifting distance surpasses the arm radius of turn, launch the tray fold of crane arm below this moment under dynamic action, object is winched on the tray fold, regains the supporting leg of crane arm and crawler belt rear and front end then.Hoisting crane transhipment object launches crawler belt rear and front end supporting leg again after assigned address, object on the pallet is winched to assigned address.The motion of supporting leg, tray fold, slippage counter weight device, crane arm part is driven by engine installation.

The multifunctional crane of the utility model; Can be in the place that big-and-middle-sized weight-lifting equipment can't arrive; Safety carry out lifting and transhipment operation: the function of existing soil-shifting, loading and unloading, the function of transportation is arranged again, be particluarly suitable in the crawl space or the ground environment of wetland, hillside fields, weak soil in operation.
