provides for easy attachment with a u bolt 20 to the rung 76 the main a braces 34 pivot at the main rod pivot 24 through which the sheath rod 18 penetrates pivoting may also occur within the sheath 12 where the sheath rod 18 penetrates it dependent on where the least amount of friction occurs when the unit 10 has a load 70 attached pivoting at either point is not undesirable pivoting occurs when the lift device 10 is pushed toward the edge of the structure 72 or rolled back onto it with or without a load 70 the worker never has to lift any of the load 70 telescope legs or otherwise manipulate the device 10 except to crank the winch 74 and roll the unit 10 the legs or main braces 34 are inside the ladder side rails 27 in this embodiment and are connected to the sheath rod 18 when the unit is attached the main braces 36 go upwardly at an oblique angle and are connected to the male top brace 44 the wheels 66 are on their distal end along with the wheel brace 62 the main braces 36 are metal channels in this embodiment the smooth side faces toward the inside of the unit 10 the cross braces 32 are between the main braces 36 these provide for strength and rigidity of the device 10.
