Claims20
A pipe installation trailer, comprising:
- a trailer frame, wherein the trailer frame comprises:
- a first portion that includes an outer structural member;
- and
- a second portion that includes an inner structural member, wherein the inner structural member of the second portion is configured to move telescopically within the outer structural member of the first portion to facilitate transitioning the pipe installation trailer between a collapsed width and an expanded width;
- and
- a braking assembly secured on the trailer frame, wherein the braking assembly comprises:
- a brake rotor;
- a brake shaft that extends out from the brake rotor, wherein the brake shaft comprises a keyed opening that is keyed with one or more flat inner surfaces that are configured to interlock with one or more flat outer surfaces keyed on a drum shaft of a pipe drum to tie rotation of the brake rotor with rotation of the pipe drum;
- and
- a brake pad configured to selectively engage the brake rotor to facilitate controlling rotation of the pipe drum on the pipe installation trailer and, thus, deployment of flexible pipe from the pipe drum.
