TECHNICAL FIELD OF THE INVENTION
[002] The present invention relates to an articulated pick and carry crane vehicle, particularly, having 0° to 360° slew telescopic boom with outriggers, providing an improved operational workability and better stability.
BACKGROUND OF THE INVENTION
[003] An articulated pick and carry crane is similar to a mobile crane designed to travel on public roads. The steering of the crane is achieved through articulation of a front body and a rear body through hydraulic cylinders. However, pick and carry cranes are designed to lift the load and carry it to its destination, within a small distance.
[004] The normal function of a crane is to lift the load and place it in a new desired location. In an articulated pick and carry crane, the load to be lifted is carried to a distance and then positioned and placed. If the distance is large, then the pick and carry crane lifts the load when stationary, moves to carry the load to new position/location and thereafter places the load. Even if the distance is small, the same procedure is required to be done.
[005] Existing articulated pick and carry cranes can lift and place the load into the forward direction only & not on the side and rear direction without shifting the crane in totality. In other words, in the existing articulated pick and carry crane, the telescopic boom lifts the load into the upward and downward direction. However, for placement of load in other than front direction of

crane it is required to shift the crane into the load placement direction. Sometimes, it is very difficult to shift the crane in busy area due to traffic or space limitations.
[006] Therefore, a pick and carry crane with improved mechanism is required to overcome the aforesaid limitations. The present invention provides one such articulated pick and carry crane designed with 0° to 360° telescopic boom thereby allowing 0° to 360° rotation of the slew telescopic boom on vertical axis without moving the crane from one direction to another direction using outriggers and hence improving workability and stability of crane.
OBJECT OF THE INVENTION
[007] The objective of the present invention is to provide an articulated pick and carry crane with 0° to 360° slew telescopic boom which improves operational workability.
[008] It is also an objective of the invention to provide articulated pick and carry crane with front and rear outriggers on the front body when working with slew duty to improve stability.
[009] Another objective of the present invention is to provide the outriggers on front side of the front body and on the rear body of crane.
[0010] A further objective of the present invention is to provide crane vehicle controls mounted on the slew frame or on the front body.
[0011] Other objects and advantages of the present invention will become apparent from the following description taken in connection with the, illustrations and examples to disclose the aspects of the present invention.

[0023] It is to be understood that the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.
[0024] It should be emphasized that the term "comprises/comprising" when used in this specification is taken to specify the presence of stated features, integers, steps or components but does not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof.
[0025] In accordance with the present invention, the proposed articulated pick and carry crane with 0 to 360 degrees slew telescopic boom comprises of: the front body and the rear Body joined through pivot pins. The steering of the crane is achieved through articulation of the front body and the rear body at pivot pins through operation of steering cylinders by steering wheel for left or right turn which is fitted in a driver cabin.
[0026] In the crane, an engine with a gearbox is mounted on the rear body to power the crane for movement on road as well as to drive a hydraulic pump to operate crane operations.
[0027] The power from engine to drive axle fitted on the front body and drive axle fitted on the rear body for movement of crane is through auxiliary gearbox and propeller shafts.
[0028] A counter weight is mounted on the rear of the rear body of the crane to provide the stability when the load is lifted from the front of crane through fixed hooks or snatch block.
[0029] A slew bearing is mounted on the front body of the crane and is fastened to the slew frame which allows free rotation movement of the slew frame in respect to the front body in the horizontal plane.

[0030] In the crane, a telescopic boom is mounted through pivot pins on the upper rear of the slew frame. The telescopic boom includes the telescopic boom sections and that can be extended through a boom extension cylinder to accomplish telescopic action. Two hydraulic cylinders are connected between the telescopic boom sections and the slew frame on each sides of the telescopic boom and the slew frame extends to allow the telescopic boom to move up and down. The boom member is also provided with hook points and hook to hang the load.
[0031] The slew frame includes a slew counter weight attached to rear of the slew frame and a winch which is mounted on top of slew counter weight.
[0032] The winch includes a drum on which rope is wound, and a hydraulic winch motor to rotate the drum in forward and reverse direction. The winch motor is driven through the power of hydraulic pump. The winch motor rotates the winch drum so that the snatch block that is coupled with front end of the rope on wire drum, moves up and down.
[0033] A slew gear box with a protruding gear tooth pinion is mounted on the slew frame. The protruding gear tooth pinion engages with the gear tooth of the slew bearing. The drive of gearbox is through a hydraulic motor which is powered by the hydraulic pump. By operating the hydraulic motor, the rotation of slew gear box in turn moves the slew frame in horizontal direction.
[0034] In proposed crane, the slew frame with slew gearbox, the telescopic boom, Boom cylinders, Counterweight, the winch and snatch block can rotate in horizontal direction in respect to the front body. Hence, the telescopic boom is connected to the rotatable slew frame, therefore, the telescopic boom of the said crane can be rotated 0° to 360° with respect to the front body. The present invention facilitates rotation of the telescopic boom of crane in any direction for position of load from 0° to 360° horizontally without moving the crane from one direction to another direction.
[0035] The driver cabin is provided on the right side of the front body of the crane. In the driver cabin, a seat is provided for the driver and operating control such as levers or handles, steering wheel etc.

[0036] On front of the front body, the outriggers (15) are provided on each side of the front body. A movable section is housed in the front body and connected to the front body through a hydraulic cylinder. On extending the hydraulic cylinder, the movable section extends outwards from the body. On contracting the hydraulic cylinder, the movable section is housed in the front body. On the far end of the movable section, hydraulic jack cylinders (13) are mounted in vertical direction. On extending/contracting the hydraulic jack cylinder, the movable section moves up and down.
[0037] On rear of the front body, another set of outriggers (16) are provided on each side of the front body. The outriggers contain multiple telescopic sections 2-3 which are housed in section 1. The sections 2-3 are extended / contracted through the extension/contraction of hydraulic cylinders.
[0038] A swing hydraulic cylinder (8) connecting telescopic outrigger (16) and the front body extends/contracts resulting in swing out of the telescopic outrigger (16) towards the rear body. On the far end of the movable sections, hydraulic jack cylinders (13) are mounted in vertical direction. On extending/contracting the hydraulic jack cylinders (13), the outrigger moves up / down and in turn, the front body moves up and down.
[0039] A hydraulic control valve is fitted on to the right side of the front body of the crane. The operation of control valve extends / contracts the cylinders (13) individually to set up the crane for slew duty.
[0040] The rear body of the crane includes engine, transmission (gearbox), auxiliary gearbox, rear axle with suitable tires, fuel/hydraulic tanks, rear suspension, engine coverings, counter weight, outriggers etc.
[0041] The front body of the proposed crane includes front axle, the slew frame, slew counter weight, tires, drive propeller shafts, outriggers, outrigger cylinders, cabin with controls etc.
