Abstract
The invention provides an improved temporary support device for multiple axle trailers with leaf spring suspension regardless of frame design. The device provides emergency towing capabilities to a trailer that would otherwise be immobile due to the failure of a spindle, bearings, spring, tire, suspension, wheel or other suspension or wheel component attached to an axle. The detachable device comprises a steel tube which extends between two leaf spring shackles and is held in place by two locking pins, a length of chain to secure the disabled axle to the steel tube, and a protective shield and locking pin to secure the chain to the steel tube. The steel tube has multiple holes to adjust the device to fit any multiple axle trailer.
