Abstract

A telescoping ladder jack supports a scaffolding plank and comprises a main member. A telescoping beam includes longitudinally spaced holes on each side of the telescoping beam and is inserted into or extracted from the main member. A locking mechanism is mounted to the main member and inserted into one of the holes to fix the telescoping beam at a desired length extracted from the main member. Ladder rung hooks are attached to a first bracket, which receives and is pivotally attached to the main member and has one of the hooks attached to each opposing end of the first bracket. A device for adjusting incline includes a second bracket mounted to a bottom of the main member (the second bracket including at least one series of recessed locking joints) and a bracing arm movably fastened to the second bracket by a locking pin oriented through a first end of the bracing arm and pivotally mounted to the first bracket at a second end of the bracing arm. A securing mechanism includes a third bracket mounted to a distal end of the telescoping beam and an adjustable pin that fits into one of the holes in the telescoping beam by passing through a slot in a top of the main member. The slot extends substantially the length of the main member, and the scaffolding plank is secured between the third bracket and adjustable pin to the telescoping beam and main member.
