Abstract
Abstract Combi-equipment functioning as transport cart and ladder, particularly boat-ladder, said equipment comprising a main frame (1) supported by wheels (9, 10) and a load-carrying member, said main frame comprising two elongate, substantially parallel side frame pieces (2, 3) and upper and lower end frame pieces (4, 5), joining the side frame pieces, as well as a number of transverse stays between the side frame parts. The equipment according to the invention is characterized in that the load-carrying member comprises a load-carrying frame (13) pivotably journalled on a transverse stay (8) or on the side frame parts, and a support frame (21) which is pivotably journalled on the load-carrying frame (13), that the support frame (21) is provided with locking means (25) designed to be brought into engagement with either the lower end frame part (5) of the main frame to give a first position of the load-carrying member, or with a second transverse stay (7) of the main frame part, said stay being located above and at a predetermined distance from said first transverse stay (8), to give a second position of the load-carrying member.

Claim 3
Dependent Claim
41 words
Equipment according to claim 1, characterised in that the load-carrying frame comprises an outer part pivotable in relation thereto and arranged to be locked in relation to the load carrying frame to provide an extended load plane or extended support member.
Claim 4
Dependent Claim
63 words
Equipment according to claim 2, characterised in that the outer part of the load carrying frame is provided with locking means which, after the locking engagement of the outer part with the load-carrying frame has been released, can be brought into engagement with the lower end frame part of the main frame, so that a third position for the load-carrying member is obtained.
Claim 5
Dependent Claim
66 words
Equipment according to c1aim 2 or 3, characterised in that the outer part of the load-carrying frame is designed to abut against the lower end frame part of the main frame, whereupon the support frame of the load-carrying frame is arranged to assume a perpendicular position in relation to the load-carrying frame, the support frame of the load-carrying frame serving as a support on the ground.
