    摘要： This work machine comprises: a first pin transitioning between an in-state where the boom and the telescopic cylinder are connected and an out-state where the connection is released; a second pin transitioning between an in state where booms are connected and an out-state where the connection is released; a main-detection device and a sub-detection device detecting the states of the first pin and the second pin; and a control unit that controls the boom based on the detection results of the main-detection device. The control unit controls the ON/OFF of a first flag indicating whether or not the main-detection device detected the combination and the ON/OFF of a second flag indicating whether or not the sub-detection device detected the combination, and detects that an abnormality has occurred in the main-detection device and sub-detection device based on the first flag and the second flag.

    摘要： An interlocking control circuit and a double-tower type crane. The interlocking control circuit is applied to the double-tower type crane. The double-tower type crane comprises a primary tower (1) and a secondary tower (2). The interlocking control circuit comprises: a primary tower control unit (100) provided on the primary tower; a secondary tower control unit (200) provided on the secondary tower; an interlocking switching unit (300) provided on the primary tower and separately communicating with the primary tower control unit and the secondary tower control unit. The interlocking switching unit is used for receiving a locking signal externally input, and sending the locking signal to the primary tower control unit and the secondary tower control unit. Under the condition that the locking signal indicates a first state, the primary tower control unit is used for controlling the primary tower to start, and the secondary tower control unit is used for forbidding the secondary tower to start; and under the condition that the locking signal indicates a second state, the primary tower control unit is used for forbidding the primary tower to start, and the secondary tower control unit is used for controlling the secondary tower to start. The described circuit design implements electric interlocking of the primary tower and the secondary tower, and improves the operation safety of the double-tower type crane.

    摘要： A cable cutter assembly (200) for an aircraft (102) hoist is disclosed, and includes an actuator assembly (210) (e.g., at least one pressurized fluid cavity (248), a first outlet port (228), and a solenoid (240) that includes a coil (270) and an armature (290)). The armature (290) is movable between closed and open positions relative to the first outlet port (e.g., via an actuation force), with the armature (290) engaging the first outlet port (228) for the closed position (e.g., a valve seal (304) incorporated by the armature) and being spaced from the first outlet port (228) for the open position. A cutter (326) body (322) includes a cutter body (322) cavity (324) that is fluidly connected with the first outlet port (228). A cutter (326) is movably disposed within the cutter body cavity (324). Disposing the armature (290) in the open position (e.g., via energizing the coil) fluidly connects the pressurized fluid cavity (248) with the cutter body cavity (324) to move the cutter (326) in a cable (106, 360) cutting direction.

    摘要： The present invention inhibits an attachment from being damaged or broken when a large transverse load is applied to the attachment as a result of a slewing operation of an upper slewing body. A slewing control device (8S) includes an attachment information acquisition unit (800A), an angular velocity setting unit (801) and a slewing control unit (802). The attachment information acquisition unit (800A) acquires attachment information for setting the maximum slewing angular velocity based on the transverse load acting on an attachment (10S). The angular velocity setting unit (801) sets the maximum slewing angular velocity of an upper slewing body (12) based on the attachment information. The slewing control unit (802) controls a slewing drive unit (7S) such that the slewing angular velocity of the upper slewing body (12) does not exceed the maximum slewing angular velocity set by the angular velocity setting unit (801).
