Specific: Delivered as part of
the "Honest John" rocket system.
Historical: The medium wrecker M62 was build on
the M40C chassis by International Harvester and Diamond
T. It was intended as a replacement for the WW II Diamond
T 969 and Ward
La France M1/M1A1
wreckers. The crane used was produced by Austin Western
and had a maximum lift capacity of 9 tons (20.000 lb.).
It was hydraulically operated with the pump driven by a
power take off from the trucks engine.
A total of six prototypes were delivered by different
firms. Among them Ernest Holmes (XM62E4) with a bed very
like the WW II Diamond T 969, and Gar Wood (XM62E1) with
a wrecker looking much like the M1A1 wrecker. The
prototypes were tested at Aberdeen Proving Ground from 14
February to 28 May 1952.
Due to licensing conflicts about the Austin Western bed
the production period was relatively short. This resulted
in the adoption of the M543 wrecker equipped with a later
designed Gar Wood wrecker bed.
In the Honest John launcher system it´s primary task was
in conjunction with assembling and loading the rocket
from the M55
truck to the launcher. Secondary task was to act as a
