Description

[0001] This invention relates to a carrier for an elongated, weighty tubular member, and more particularly to such a carrier suitable for use in loading thereon at a first location, transporting to a second location and dispensing along a boundry line along the ground, a flexible, tubular member intended for use as an erosion barrier.

BACKGROUND OF THE INVENTION

[0002] On various sites in which vegetation has been removed and perhaps where building construction or a similar activity is contemplated, it has been a common practice to position elongated tubular members formed of a flexible, mesh material containing mulch and perhaps other filler materials, about the periphery of such a particular site, to serve as a barrier to eroded soil and other disturbed materials and objects. Typically, in use, such elongated tubular members are produced at a distant site, loaded on pallets and delivered to a designated site and then manually removed from such drop-off area, manually carried to a perimeter segment of the site, set on the ground along the site perimeter and then staked to the ground. Such segments of tubular members thus form a barrier to eroding soil within the perimeter of the particular site.

[0003] Such tubular barrier members typically are 18 inches in diameter, 100 feet in length and weigh approximately 3,250 pounds. Offer, 8 to 10 men are required to lift, haul and position such members, resulting in substantial handling costs.

[0004] In view of the foregoing, it is the principal object of the present invention to provide an improved means and/or method of handling such barrier members at various sites which would reduce the amount of labor required thereby decreasing labor costs, freeing personnel for other assignments and expediting the formation of a barrier about the perimeter of a construction or other site.

SUMMARY OF THE INVENTION

[0005] The principal object of the present invention is achieved by means of a carrier attachable to an arm member of a prime mover, which includes an inverted, U-shaped frame member provided with an upper component and a pair of spaced, depending components, a roller spaced parallel to the upper component and journalled in the lower ends of the spaced depending components; means provided on such roller for detachably securing an end portion of such tubular member thereto; means for rotating the roller for winding such attached tubular member thereon and means for attaching such frame member to the arm of such prime mover. Preferably, the space formed by the frame components is sufficiently large to accommodate the size of the contemplated barrier member, the roller is provided with a suitably positioned means for attaching an end portion of the member to be wound on the roller, and the motor driving the roller includes a slew drive functional to hold radial and axial loads and transmit torque for rotating the roller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

[0011] Referring to FIG. 1 through 3 of the drawings, there is illustrated a prime mover 10 consisting of a tractor utilized to lift, transport and position a carrier 11 functional to attach haul and detach a tubular barrier member 12 supported on a pallet 13. Tractor 10 includes a base structure 14 supported on a set of crawler tracks 15, an upper structure 16 provided with an operator's station, supported on the base structure for pivotal movement about a vertical axis, and a front end assembly including a boom 17 pivotally connected to upper structure 16, a cylinder assembly 18 operatively interconnecting upper structure 16 and boom 18 for pivotal movement of the boom about a horizontal axis, an arm member 19 pivotally connected between the ends thereof to the fee end of boom 17, a cylinder assembly 20 operatively interconnecting a portion of boom 17 and an end of arm member 19, a set of transversely spaced arm members 21, 21 pivotally mounted at one set of ends thereto to arm member 19 and a second set of ends thereof to a rod connected to a set of member links 22, 22 and a cylinder assembly 23 operatively interconnecting an end of arm member 19 and the connecting pin of members 22,22.

[0012] Carrier 11 generally includes a housing frame 30, a roller assembly 31 and a motor assembly 32. Frame 30 has an inverted U-shaped configuration including an upper wall component 30a and a pair of spaced, depending end wall components 30b and 30c. Component 30b further consists of a pair of spaced leg members interconnected by a cross member 30d disposed intermediate such leg members and a pair of plate members 30e and 30f interconnecting the outer and inner sides of the lower ends of the leg members. Roller assembly 31 is spaced parallel to frame component 30a and consists of a roller 31a provided with a pair of shaft portions at the ends thereof journalled in aligned bearings mounted on the lower inner side of frame component 30c and the inner side of inner plate member 30f. Such roller is rotatable in forward and reverse directions by slew drive motor 32 mounted on plate member 30e, having a drive shaft coupled to an end shaft of the roller assembly. Operation of such motor may be provided by means provided on the carrier or remote means as may be provided in the operator's station on the prime mover of the carrier.

[0013] The size of the space defined by the carrier frame members 30a, 30b and 30c is determined by the length and diameter of each tubular segment 12 intended to be wound on roller assembly 31. In the use of tubular segments of 18 inches in diameter and 100 feet in length, such space has been found to be 4 to 5 feet in depth and 8 feet in width. Each of such tubular members as described consists of a length of tubular mesh material, filled with a material such as mulch and closed in either one or both of the ends. Filled with mulch, a member of such diameter and length can weigh in the amount of 3,500 pounds.

[0014] Carrier 11 is connectable to arm member 23 and links 22,22 by means of attachment member 40 secured to the center of upper wall component 30a. Such member includes a support platform 41 secured to component 30a and a pair of laterally spaced plates 42 and 43 provided with two pairs of transversely aligned pin holes 44, 44 and 45, 45. The carrier is detachably connectable to the free ends of arm member 19 and links 22, 22 by a set of pins to connect the carrier to the front end assembly of tractor 10 as shown in FIG. 1 through 3.

[0015] In the use of carrier 11 to load, transport and unload a segment of tubular barrier member 12 as shown in FIGS. 1 through 3, the carrier is first mounted on the front end assembly of the prime mover utilizing attachment 40, and then the tractor and the front end assembly thereof are maneuvered to position the roller assembly thereof in proximity to barrier segment 12 coiled atop pallet 13. With the carrier thus postured, an end of the segment in manually griped, inserted into the opening in the carrier and manipulated to insert and jam a loose portion of the member into a slot 50 of a connector 51 rigidly secured on the cylindrical surface of the roller assembly adjacent depending frame member 30c to position and attach an end of member 12 as shown in FIG. 1. With an end of member 12 thus secured to an end of the roller, motor 32 is operated to draw and wind member 12 onto the roller to a condition as shown in FIG. 2 with an end of member 12 simply suspended as shown. With the barrier member thus loaded and the carrier elevated, the tractor then maneuvers to transport the loaded barrier segment to a perimeter area as shown in FIG. 5 and then proceeds to simultaneously operate motor 32 in reverse to cause the loaded segment to unwind and fall long a perimeter path as the tractor guides the carrier. As the barrier segment is thus unwound and allowed to fall along or adjacent to the perimeter line, one or two workmen attend to any required repositioning of the segment along the perimeter line and then securing the segment therealong with a set of spikes 60. As the carrier transports the wound segment to the perimeter site, the slew drive provides resistance to any reverse torque that would cause the mound segment to unroll and prematurely be deposited on the ground.

[0016] The carrier and method of use thereof as described, not only require less attending personnel but significantly reduces the amount of time required to transport and maneuver multiple segments of barrier segments about the perimeter of a land site.

[0017] From the foregoing detailed description, it will be evident that there are a number of changes, adaptations and modifications of the present invention, which come within the province of those persons having ordinary skill in the art to which the aforementioned invention pertains. However, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the appended claims.
