Claim:
1. An industrial truck accommodating an operator therein, the industrial truck comprising: a lift mast having a forward end and a rearward end and a height adjustable load support disposed on said forward end of said lift mast; an overhead guard disposed on said rearward end of said lift mast facing away from said height adjustable load support and being configured to guard against falling loads and objects and so protect the operator from injury; said lift mast further having an adapter disposed on said rearward end and configured for accommodating said overhead guard thereon; said lift mast defining two lateral sides; said adapter having two flat adapter limbs having respective flat sides connected to corresponding ones of said lateral sides of said lift mast; said adapter limbs having respective free ends and being connected to said mast so as to cause said flat sides thereof to be mutually adjacent and lie in respective mutually parallel vertical planes; said adapter including a connecting web interconnecting said free ends in spaced relationship to said lift mast at the rearward end thereof; said overhead guard having two projecting connecting limbs configured to lie flat against the flat sides of corresponding ones of said two adapter limbs thereby defining first and second pairs of adapter and connecting limbs; first and second fastener sets for connecting the limbs of corresponding ones of said pairs to each other with the fasteners of each set extending in a direction perpendicular to corresponding ones of said vertical planes so as to provide a rigid connection between said overhead guard and said adapter wherein said fasteners undergo shear stress in response to said falling loads; and, said connecting web being a thin flat member and being orientated relative to an operator so as to minimize any obstruction to vision of the operator when looking upward along said lift mast.
