Abstract

A fishing net crane (0) with a net layer roller (4) with a corkline stacker arm (5) mounted on a corkline stacker bracket (17) on the net crane (0) wherein the corkline stacker arm (5) carries a corkline stacker sheave (6). The net crane comprises a vertical arm (1) on a rotating bracket (16) turning about a vertical axis in a slewing bearing (141) on a crane base (14) in the structure of the ship, and wherein the corkline stacker arm (5) is mounted on a corkline stacker bracket (17) on said vertical arm (1). The bracket (17) has an inner slewing bearing (511) which holds an inner arm (51) which outer end has an elbow slewing bearing (512) which holds an outer arm (52) with an outer slewing bearing (513) which holds a corkline stacker fork (54) with its corkline stacker sheave (6). Preferably the slewing bearing axes are vertical.

Abstract

A tension control device (20) for an anchor line rope (10) of large diameter, which winds off or onto a winch drum (4) at a marine vessel (6) wherein characterizing features are an arm (22) with a first (23), inner link arm with a first sheave arranged near the first link arms outer end, a second, intermediate link arm (24) arranged rotatable adjustable on the first inner link arm and arranged with a second intermediate sheave (25) near the second link arm's outer end, and a third, outer link arm (26) arranged rotatable adjustable on the second, intermediate link arm and arranged with a third sheave (27) near the third, outer link arm's outer end wherein the second, intermediate link arm's angle is regulated by use of a first actuator (24a) arranged between the first, inner link arm and the- second link arm wherein the third, outer link arm's relative angle to the second, intermediate link arm is regulated by a second actuator (26a). Each sheave comprises a brake (23m, 25m, 27m).
