摘要： Snatch blocks can be used for lifting loads. A cord is attached to the load and passed over the axle of a snatch block that is suspended above the ground. A person can raise the load by pulling on the cord's free end. The load will fall if the cord is simply released. The snatch block can have a pinch rod. Moving the cord to an engagement angle causes the cord to engage the pinch rod such that loosening the cord moves the pinch rod to a pinch position. At the pinch position, the pinch rod pinches the cord against the axle and prevents the cord from moving further and lowering the load. Pulling the free end of the cord moves the pinch rod from the pinch position. The load can be lowered when the pinch rod is not in the pinch position.

摘要： A hoist system having a drum primarily self-contained within a batten, for raising and lowering lighting, sound equipment, curtains and the like, often in a performance environment. The compact system is highly scalable to a variety of spaces and applications, including school and public theaters and concert halls, as well as some homes, private business, etc. The hoist system may be adapted with safety mechanisms including an overspeed detector, which may comprise a centrifugal detection mechanism coupled to an elongate member of the system; dampening means; a compact mechanism for trimming or adjusting an operative length of elongate member; stabilizing pipe shaft bearings; elongate member diverter pulley mechanisms load balancing termination points. Additional features include various alternative combination hoist implementations and orientations, and alternative incorporated attachment mechanisms for use with the hoist system.

摘要： The fastenings of the wire ropes for loading containers are subjected to huge stresses, making it necessary to use screwed-in robust grips.The systems currently installed in these cranes for fixing ropes are fixed, screwed-in grips.A much more versatile and flexible system is presented that is based on a wedge mechanism which allows automatic and instant actuation (remotely controlled).The assembly includes the sliding clamps, the actuation of these clamps, necessary additional guides and tightening device for tightening the ropes.This solution allows: Performing the rope changing operation with the jib hoisted, thus allowing the maneuvers of vessels and the operation of contiguous cranes. Reducing the rope replacement times. Using the anchoring element (clamps)+tightening device as a mechanism for tightening the length of the ends. Possible misalignments of the spreader can be corrected instantly.

摘要： A cable brake has an electromagnet releasably retaining a mass that falls down guide rods under the effect of gravity and impacts a first arm of a trigger lever. Upon impact by the mass, the trigger lever rotates a second arm with a pawl to release a crossbar, whereupon pressure springs press a moveable brake plate against a cable strand to halt the cable strand. A return mechanism utilizes a screw and cooperating nut or a coupler to return the moveable brake plate and pre-stress the pressure springs.

摘要： A cable brake has an electromagnet for selectively releasing a mass to fall down guide rods under the effect of gravity and impact a trigger lever to release a crossbar from a pawl, whereupon pressure springs move a brake plate against a cable strand to halt the cable strand. The pressure springs extend between a first pressure plate at the brake plate and a spaced second pressure plate that can be displaced along a path by a cooperating screw and nut to pre-stress the pressure springs. The pressure springs are relaxed in one end position of the path whereby the crossbar connected to the first pressure plate by a release bar is engaged by the pawl in a starting position.

摘要： A failsafe stable cleat with automatic in-line line-locking includes a frame having proximate and a remote sides on substantially opposite sides of the frame and formed with a passageway, extending between the proximate and remote sides, for receiving a line and generally defining a cleat center line along which a line can move along a first line releasing direction from the proximate to the remote sides and a line pulling direction from the remote to the proximate sides; attaching members for attaching the frame to a support surface. A cam on the frame on one side of the passageway has a line engaging portion spaced a predetermined distance from the support surface, the cam being movable between a line releasing position and a line locking position. A pusher on the frame is positioned on an opposite side of the passageway in relation to the cam for selectively applying a force on the line in the direction of the cam A cam biasing member tends to urge the cam to disengage from the line while a pusher biasing member normally tends to move the line across the gap into contact with the cam while permitting the line to return to the passageway out of contact with the cam when sufficient tension is applied by the user off the cleat center line to create a force component to offset the pushing force created by the pusher biasing member. This promotes unlocking of the line and allowing the line to move in the first line releasing direction, engagement of the line by the cam to the line locking position creating a force couple which is a function of the predetermined distance, that tends to separate the frame from the support surface. A stabilizing element compensates for and offsets the force couple independently of the dimensions or configuration of the frame.

摘要： In order to increase the operational safety and to reduce the rope wear, hoisting/lowering apparatus comprise one or a combination of novel features: an adaptor (3) is provided in order to allow the attachment of accessories (50), preferably by insertion. Possible accessories are e.g. holders having a loop for the attachment of hooks, and single or multiple blocks for the formation of lifting blocks. Substantially, the adaptor is formed of a number of slot-shaped recesses which are transversely traversed by rod-shaped retaining elements (11, 9). One of said retaining elements (9) is displaceably mounted in order to allow the attachment resp. detachment of an accessory (50). Another measure is to provide a rope stop (102) on the traction side. The rope (103) runs through the rope stop (102) and drives a knurled wheel (110). At a given rope speed, the wheel is coupled to a pivotable brake appendix (118) by means of a centrifugal coupling (113, 115). The rope (103) is then squeezed and blocked between the appendix (118) and a counterpart (108). A third measure consists in providing guiding rolls (36, 37) in order to ensure a spiral-shaped travel of the rope (103) which is free of crossings.
