A hose trolley with a carrier frame comprising: a guide handle ; a hose drum held in the carrier frame , the hose drum adapted to carry a hose reel wound around the hose drum ; and a support element attached to the carrier frame , the support element adapted to support the hose trolley on the ground surface ( G ), wherein the support element is pivotable between an operational position ( P1 ) and a non-operational position ( P2 ), such that the operational position ( P1 ) is associated with an operational configuration of the hose trolley and the non- operational position ( P2 ) is associated with a non-operational configuration of the hose trolley ; and wherein the support element defines at least one pivot opening , such that the support element is pivotable around the pivot opening relative to the carrier frame between the operational position ( P1 ) and the non-operational position ( P2 ); characterized in that: the support element further includes at least one protrusion adapted to move between a first position ( X1 ) and a second position ( X2 ) relative to the support element such that the at least one protrusion is biased to remain in the second position ( X2 ); wherein when the at least one protrusion is in the first position ( X1 ), the at least one protrusion is enclosed within the support element ; and wherein when the at least one protrusion is in the second position ( X2 ), the at least one protrusion extends at least partially outside the support element through the pivot opening such that the support element is pivotable about the at least one protrusion . a guide handle ; a hose drum held in the carrier frame , the hose drum adapted to carry a hose reel wound around the hose drum ; and a support element attached to the carrier frame , the support element adapted to support the hose trolley on the ground surface ( G ), wherein the support element is pivotable between an operational position ( P1 ) and a non-operational position ( P2 ), such that the operational position ( P1 ) is associated with an operational configuration of the hose trolley and the non- operational position ( P2 ) is associated with a non-operational configuration of the hose trolley ; and wherein the support element defines at least one pivot opening , such that the support element is pivotable around the pivot opening relative to the carrier frame between the operational position ( P1 ) and the non-operational position ( P2 ); characterized in that: the support element further includes at least one protrusion adapted to move between a first position ( X1 ) and a second position ( X2 ) relative to the support element such that the at least one protrusion is biased to remain in the second position ( X2 ); wherein when the at least one protrusion is in the first position ( X1 ), the at least one protrusion is enclosed within the support element ; and wherein when the at least one protrusion is in the second position ( X2 ), the at least one protrusion extends at least partially outside the support element through the pivot opening such that the support element is pivotable about the at least one protrusion . the support element further includes at least one protrusion adapted to move between a first position ( X1 ) and a second position ( X2 ) relative to the support element such that the at least one protrusion is biased to remain in the second position ( X2 ); wherein when the at least one protrusion is in the first position ( X1 ), the at least one protrusion is enclosed within the support element ; and wherein when the at least one protrusion is in the second position ( X2 ), the at least one protrusion extends at least partially outside the support element through the pivot opening such that the support element is pivotable about the at least one protrusion . <EOS>
