Kelly Bar is the key part for a Piling Rig, to make high reliable Kelly bar, we have to follow rules as below:
1. Top quality material
2. High welding quality
3. Appropriate heat treatment
4. Professional design
The invention comprises a reverse telescopic kelly bar that includes an outer bar, any number of middle bars, and an upper inner bar. Each section has its own driver that either rests on top of the adjacent, lower larger diameter section or is engaged to the rotary. The entire assembly is suspended by a swivel attached to a multi-shieve traveling block. When a section is rotated, it is either rotated by its driver via the rotary or by the connected and adjacent lower and smaller diameter section. Upper inner lugs are provided on the inside of the hollow sections. These upper inner lugs are located near the upper part of the middle bar and lower outer sections so that they can receive torque, if required by the cross-section, when fully extended from one section to another section below the rotary. A thick ring is welded to the bottom of the middle section and upper inner section. The inside lugs and the bottom ring also act as a stop to hold the adjacent sections together when they are fully extended so that adjacent sections can be supported from the other. Depending on the cross-sectional shape, the sections also may have outside drive lugs to transmit torque from the rotary and to transmit torque to the upper inner lugs of the next larger bar. The sections may have slots (or holes) and pins to connect each bar together and support the hanging sections. Square sections or other multi-sided sections may not need upper inner or outer lugs for purposes of transmitting or receiving torque. A lug would be needed for hanging the bar on the heavy ring.
