Abstract
A crane barrier access warning system suspended by four or more pinned adjustable telescoping supports, which extend outward from a cranes lower car body between the tracks. One of the telescoping members end inserts into a mounting frame, which comprises of other pinned adjustable telescoping components, so that it can be fitted to the frame or track beams. This entire safety barrier system is erected without tools. The components that form the actual safety barrier surrounds the whole crane and are suspended from it so that the safely barrier moves with the crane. Suspension components are adjustable through their pinned telescoping members so that the invention can fit different sized cranes. All the parts can be separated and fully retracted for shipping or storage.

DETAILED DESCRIPTION OF THE DRAWINGS
[0020] It is to be duly noted that the identified sections and components in each drawing view refer to a set of each to comprise the entire invention. A front and back set, and left and right sides. In order to present orderly neat drawings, it was necessary to present them in this manner. Most of the terms here in are commonly known by persons familiar with the field of the art.
[0021] Referring to FIG. 1 is shown a crawler crane tracks and car body from a bottom view, 1 depicts one section of the invention's extension supports that telescope fitted over 2, the mid support and is pinned off at the proper hole setting, while 2 points to the mid portion of the support which comprises of half of the hinge 3 (see FIG. 3). 4 shows the plastic ribbon, tape, or fiber rope which comprises the side barrier portion. The opposite track side barrier is the same which is not labeled. S depicts the counter weight portion of the upper rotating super structure that is the farthest outer end of the swing radius, 6 depicts the current inventions mounting frame center section member. 7 depicts one of the two crane car body track beams. The opposite track beam is not labeled. The mounting frame is pinned to the proper adjustable hole settings with pins 8 and 9. Two other size adjustment pins on the mounting frame are depicted by 10 and 11 on the opposite side mounting frame. Two other adjustment pins are not visible in this view (see FIG. 2). The front mounting frame not labeled is exactly the same as the depicted rear 6. 12 shows a rigid plastic tubing section as it is inserted end to end into the others to comprise the total width of the front barrier, and is attached at the center of the telescoping extension support 1 by a pin 13 adjoining the two in a manner that allows the barrier to pivot at this connection point. The front barrier not labeled is exactly the same. 14 and 15 depict the upper rotating super structure counter weight right and left positions when it is over the side of the tracks and shows its approximate distance from the right and left ribbon or rope barriers 16 and 17 depicts the crawler cranes tracks as they are connected to the car body positioned in between. 18 points to the front portion of the crawler cranes upper rotating structure. 19 on the front invention end depicts the adjustment pin for the telescoping extension members as it is set into the proper hole setting to position the outer rigid plastic tubing barrier to the proper distance of the cranes swing radius. The extension adjustment pin on the rear end is exactly the same. 20 depicts the inner extension support, and its end that makes up the other half of the hinge 3. 21 depicts the pivot pin connecting the two halves of the hinge (also see FIG. 3). 22 depicts one of the four mounting frame adjustable telescoping members as it is fitted to the track beam(s).
