The upper end of the pulling board (4) for a super-lifting counterweight is connected with the upper end of the super-lifting mast (5) by a lifting rope.
A protruding end of a lower cross beam of the C-shaped hanging bracket (25) is provided with at least a fixing point for a lifting rope (26) or a lifting rope winding/unwinding device.
The rope supporting apparatus can reduce a drooping length of a lifting rope and enhance construction safety of the tower crane.
Also disclosed are a tower crane jib, lifting rope anti-falling method thereof and a tower crane.
The idler roller is displaceable between an engaged position and a disengaged position based on an amount of tension on the lifting rope.
The drum is used to wind the hoist cable or the drag cable.
According to another aspect of the invention, the hoisting cable is provided as a multiple fall cable and a hoist cable retention device is provided on the boom.
(b) shall be positioned in such a way that the hoist cable is vertical at all times while a load is being hoisted.
As a result, a spring device is arranged on at least one hoist cable bearing point (11, 12, 13) of each hoist cable (10) of the straddle carrier (1) which enables instantaneous loads transferred to the hoist cable (10) to be dampened.
A command (370) to change a current length (352) of the hoist cable (340) to substantially the desired length (366) may be generated.
Furthermore, the hoisting mechanism has a hoisting cable (11) and a hoisting-cable drive (12).
A displaceable hoisting-cable guide (17) is provided for the hoisting cable, in such a manner that displacement of the displaceable hoisting-cable guide changes the length of the path.
When the raising wire vibrates, the attenuation member contacts the raising wire and attenuates said vibration.
One of the first and second hoist ropes is driven by the hoist.
The second hoist rope (10) passes over a pulley (17) mounted between the first hoist rope (9) and a bridle (20) extending to the front of the bucket at (19).
Hoisting-cable drive (12) means (14, 15, 16, 17) form a path for the hoisting cable.
A crane lift cable is attached to a spreader bar.
The crane has a winch (35) and an associated hoisting cable (36) for hoisting a load.
Use adequate lifting cable (wire or rope) of sufficient
A lifting cable is arranged to cradle the component between the crane and the lifting device.
■ Use adequate lifting cable (wire or rope) of sufficient
A lifting cable is disposed between the plurality of mast sections.
A hoist rope (18) for an elevator is formed from synthetic, non-metallic materials.
The chamber is connected via a lifting cable (29) to a take up device (41) on the floating structure for lengthening and shortening the lifting cable.
Design of the arm so that the lifting cable remains stationary at the heave compensating member during heave compensation, results in an increased lifetime of the lifting cable.
