摘要： PROBLEM TO BE SOLVED: To surely hold each individual brake lever in a symmetrically opened state in time of releasing the brake even if a gap produced by wear in brake lining is controlled so as to be automatically reduced by a lining automatic wear controlling device, at a time when this brake lining is worn out. SOLUTION: A disk braking device overhangs a stopper 58 screwed with an adjusting bolt 56 in the vertical direction, to the outside, attaching it to the lower end side of a brake lever 3A at the side receiving a leaning force in time of opening operation. In addition, a pedestal 59 is installed on a base plate 1 just under the stopper, and a pinion 61 is externally fitted in an upper end of the adjusting bolt 56 via a one-way clutch so as to make the bolt 56 rotatable only in a direction tightening it downward, and it is engaged with the pinion 61 with the specified backlash and a rack 57 extending in the rocking direction of the brake lever 3A is supported from the side of the base plate 1.

摘要： PURPOSE:To improve work efficiency by respectively liftably mounting lift frames, having a table possible to load a carriage with a boat mounted, to a supporting member in a plurality of booms which are secured to a turning frame and extended in a transverse direction. CONSTITUTION:For unloading a boat 17 on the sea 9 from a quay 1, a carriage 15, on which the boat is mounted, is previously loaded on a table 14, thereafter it is lifted to predetermined height along lift frames 10 by a winding winch 19, next by turning booms 6a, 6b with a turning frame 4, the boat 17 is lowered on the sea 9 by positioning the table 14 on the surface of water. While for loading the boat 17 on the ground from on the sea 9, work is performed by a procedure reverse to the above described. Thus, the service life of a device is increased as well as the work time required for lift work can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an overload preventive method and a device of a suspension device capable of preventing cutting of a rope body by surely avoiding an overload applied to the rope body such as a cable for suspending and supporting a suspending object when performing work by suspending the suspending object in the sea. SOLUTION: This overload preventive method of the suspension device (an observing device 3) is arranged on a deck 2, and performs the work by overhanging to the side of a hull 1, and suspending the suspending object in the sea. Depression and elevation operation of the suspension device is controlled so that a distance A0 between a delivery position of the rope body and a virtual reference sea surface L is held constant in response to swinging of the hull 1.

摘要： PROBLEM TO BE SOLVED: To provide an auto-tension device capable of automatically controlling tension applied to a string material to be no more than predetermined tension and changing-over between a tension applied condition and a hoisting condition with simple operation, independently from up-and-down movement due to waves given by hoisted objects and a ship. SOLUTION: An auto-tension device for adjusting the tension of a hoisting mechanism mounted on a ship crane includes a reduction gear 1, a lifting hydraulic motor 3 (a lifting fluid pressure driving source) connected to a driving shaft 2 of the reduction gear 1, a tension applying hydraulic motor 5 (a tension applying liquid pressure driving source) connected to a driving shaft 4 of the reduction gear 1, a drum 7 connected to an output shaft 6 of the reduction gear 1, a wire rope 8 (a string material) wound on the drum 7 and a hydraulic controller (a fluid pressure controller) for supplying and stopping operating oil to the motor 3 and changing-over its supply direction to provide supply and stop of the operating oil to the motor 5 and hold is oil pressure.

摘要： PROBLEM TO BE SOLVED: To provide a delivery device capable of delivering and winding a string material such a wire rope in order without causing out-of-order winding with a lighter hook. SOLUTION: A crane delivery device includes a first sheave 19 pivotally supported at the end of a jib 3 so as to be rotatable for circumscribing a wire rope 15 (a string material), a second sheave 20 arranged facing the fist sheave 19 with the wire rope 15 held therebetween so as to be rotationally driven to the direction of delivery of the wire rope 15 with a hydraulic motor 21 (a liquid pressure driving source) and a hydraulic controller (a liquid pressure controller) for controlling the supply and stop of operating oil to the hydraulic motor 21 and the flow rate and oil pressure thereof. The wire rope 15 is delivered or wound up while applying predetermined tension to the wire rope 15 between each of the sheaves 19, 20 and the drum 14.

摘要： PURPOSE:To facilitate transfer riding to a boat or the like despite the tide in its rise and fall or the like by providing a rotatable ground ladder in the on-the-ground side of a tide embankment and a telescopically movable sliding ladder turnably connected to the upper end of the ladder in a side of the water surface. CONSTITUTION:When a level of water is vertically changed by the tide in its rise and fall or the like, a sliding ladder 14 is telescopically slided for a water surface side ladder 10. In the case of a tide embankment 1 changing its distance to a boat or the like on the water level 3, by turning the water surface side ladder 10 for a ground side ladder 5 while telescopically sliding the sliding ladder 14 for the water surface side ladder 10, transfer riding to the boat or the like on the water level 3 is facilitated. While in the time of stormy weather of typhoon or the like, the sliding ladder 14 is contracted and completely retracted in the water surface side ladder 10, under this condition, the water surface side ladder 10 is turned to the on-the-ground side and positioned in an upper part of the on-the-ground side ladder 5. In this way, a ladder device, being stored on the ground, can be prevented from being damaged.
