Claims18
A connection system for connecting sections of a catwalk trough for conveying tubulars to a drill floor, comprising:
- a first connection piece having a pin member and a first boss member;
- a second connection piece having a first opening configured to receive the pin member, a second opening configured to receive the first boss member, and a second boss member;

A method of connecting sections of a catwalk trough for conveying tubulars to a drill floor, comprising:
- inserting a pin member of a first connection piece into a first opening of a second connection piece;
- inserting a first boss member of the first connection piece into a second opening of the second connection piece such that a hole formed in the first boss member aligns with a hole formed in a second boss member of the second connection piece;
- and
- inserting a pin into the holes of the first boss member and the second boss member when aligned to connect the first connection piece to the second connection piece.
1 more element
A connection system for connection sections of a catwalk trough for conveying tubulars to a drill floor, comprising:
