Abstract
A hand truck having a wheeled upright frame is provided at its lower end with a load-supporting nose member swingable between raised and lowered positions, the nose member being biased to its raised position and provided with detent means for releasably latching the nose member in its lowered position. The nose member is pivoted to the upright frame in such manner that when the nose member is in its lowered, load-supporting position the nose member abuts and is supported by the upright frame member, thereby reinforcing the nose member without the need for external bracing. The upright frame carries an extensible and retractable sub-frame to enable the truck to be used for transporting loads of greatly varying height.
