Abstract
Abstract A device for handling and moving generally cylindrical loads, such as cable reels, rolls of paper, sheet metal, and the like, comprising a frame supported by wheels or the like and provided with vertically pivotable, laterally movable telescoping arms for retentive engagement with the load to move said load toward and away from a load-supporting surface of said frame. The device is characterized in that said load-supporting surface is a part of a cradle having a wedge-shaped roll-on/roll-off portion at its free edge and a downwardly curved surface portion forming the actual load-supporting surface; that said cradle is tiltable about a shaft, mounted beneath the downwardly curved portion between a position in which its wedge-shaped portion connects to the floor, and a transport position in which it is spaced from said floor; and that said arms are individually or jointly telescopically movable past and beyond said cradle and are provided with engagement means adapted to engage with the load, the cable reel or the like during loading and unloading thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A device for handling and moving generally cylindrical loads, such as cable reels, rolls of paper, sheet metal, and the like, comprising a frame supported by wheels; a load-supporting surface supported on said frame; vertically pivotable, laterally movable telescoping arms for retentive engagement with the load to move the load toward and away from said load-supporting surface; said load-supporting surface including a cradle having a downwardly curved concave seat portion, and a downwardly sloping substantially planar wedge shaped ramp extending from said seat portion in the direction of the ends of said telescoping arms which are for engaging the load; and a transverse shaft supported by said frame, spaced from the ground surface supporting said wheels, and mounted beneath said downwardly curved seat portion; said cradle being tiltable about said shaft; said telescoping arms being movable past and beyond said cradle and having engagement means on their free ends adapted to engage with said cylindrical load during loading and unloading thereof.
Claim 2
Independent Claim
161 words
A device for handling and moving generally cylindrical loads, such as cable reels, rolls of paper, sheet metal, and the like, comprising a frame supported by wheels; a load-supporting surface supported on said frame; vertically pivotable, laterally movable telescoping arms for retentive engagement with the load to move the load toward and away from said load-supporting surface; said load-supporting surface including a cradle having a downwardly curved concave seat portion, and a downwardly sloping substantially planar wedge shaped ramp extending from said seat portion in the direction of the ends of said telescoping arms which are for engaging the load; and a transverse shaft supported by said frame, spaced from the ground surface supporting said wheels, and mounted beneath said downwardly curved seat portion; said cradle being tiltable about said shaft; said telescoping arms being movable past and beyond said cradle and having engagement means on their free ends adapted to engage with said cylindrical load during loading and unloading thereof.
Claim 3
Dependent Claim
14 words
The device of claim 1 further characterized by said arms being individually telescopically movable.
Claim 4
Dependent Claim
14 words
The device of claim 1 further characterized by said arms being jointly telescopically movable.
Claim 5
Dependent Claim
39 words
The device of claim 1 further characterized by said frame having two freely entending beams between which said cradle is mounted; and control means mounted between said cradle and said frame to tilt said cradle about said transverse shaft.
Claim 6
Dependent Claim
24 words
The device of claim 4 further characterized by said control means including hydraulic piston and cylinder assemblies connected between said cradle and said frame.
Claim 7
Dependent Claim
38 words
The device of claim 1 further characterized by said shaft about which said cradle is tiltable being located adjacent to a vertical plane extending through the center of a cylindrical load resting on said downwardly curved seat portion.
Claim 8
Dependent Claim
24 words
The device of claim 1 further characterized by piston and cylinder assemblies connected to said arms to accomplish the telescoping movement of said arms.
