Problems solved by technology

Activating the brake configuration in such a situation would cause either the drill string to break during the upward movement of the platform, or the platform would not be able to follow the wave movement and thus in the worst case the platform would be pulled into the water

Embodiment Construction

[0021] The embodiment of the hoist brake system shown in the drawing comprises a schematically shown brake arrangement 100 comprising four spring-activatable disc brakes 1 .

[0022] Other embodiments of the invention are contemplated having a plurality of braking arrangements, such as precisely two, precisely three or more braking arrangements.

[0023] It is also conceivable that the unique brake configuration assembly of another embodiment of the invention comprises a different number of brakes, such as disc brakes, for example exactly one, exactly two, exactly three, exactly Say five or more.

[0024] The lifting device brake system can be set on a lifting device with a power of 9000 PS, for example.

[0025] Each of the disc brakes 1 comprises two hydraulically operable piston / cylinder arrangements 1', by means of which the braking effect achieved by the corresponding disc brake can be reduced by means of the piston / The cylinder arrangement 1' is configured to act aga...

Abstract

The invention relates to a lifting-device brake system, comprising at least one brake assembly (100) that can be activated by spring force, at least one piston / cylinder assembly (1'), which can be hydraulically or pneumatically actuated and by means of which the braking effect achieved by the at least one brake assembly (100) can be reduced by at least partially overcoming the spring force, and a hydraulic or pneumatic assembly (200), which provides the hydraulic or pneumatic pressure required to actuate the at least one piston / cylinder assembly (1') and which comprises an apparatus by means of which the hydraulic or pneumatic pressure that is applied to the at least one piston / cylinder unit (1') can be optionally permanently maintained.

Description

technical field [0001] The invention relates to a lifting device braking system comprising: at least one spring-activatable braking arrangement; at least one hydraulically or pneumatically actuatable piston / cylinder arrangement, by means of which piston / cylinder arrangement can be reducing the braking effect achievable by at least one brake arrangement at least partially against the spring force; and a hydraulic or pneumatic arrangement providing hydraulic or pneumatic pressure required to operate said at least one piston / cylinder arrangement. [0002] The present invention therefore relates not only to a hoist braking system with exactly one spring-activatable brake arrangement, but also to a hoist braking system with more than one, for example exactly two , precisely three or more spring-activatable brake arrangement components. Background technique [0003] Each spring-activatable brake arrangement can itself have exactly one or more, for example exactly two, exactly thr...
