The invention discloses a multi-bar linkage mechanism based conveyor, comprising a gantry system, a multi-bar linkage mechanism based conveyor boom, a boom support, a two-drum winch, a roller unit and an automatic control system. The gantry system, the two-drum winch and the boom support are mounted on a deck of a hull. The conveyor boom is formed of multi-bar linkage mechanisms, the movement of which can be changed. Rollers are mounted on the conveyor boom. The rear segment of the conveyor boom is articulated with the boom support. The two-drum winch is connected to the multi-bar linkage mechanism based conveyor boom via a steel wire rope and by a set of gantry pulleys. A hydraulic device and a control device are arranged between adjacent multi-bar linkage mechanisms. A tension sensor is arranged at an end of the steel wire rope. The whole conveyor is controlled by the automatic control system.

The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.

A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.

A loading arm device, serving in particular for loading fluids, including a main arm supported by a base station. An external arm is pivotally connected with the main arm. Further, the rear part of the main arm is connected with a counter-weight arm. A coupling element guarantees that at different swivel positions, the counter-weight arm is arranged parallel to the external arm. Further, switching elements are provided to trigger a switching operation at a maximum scissors angle between the main arm and the external arm. One of the switching elements is fixedly connected with the counter-weight arm or the external arm, and the other switching element is rotatably connected with the main arm.

This disclosure refers to a device for assisting in the loading of bulk carriers even in rainy weather. Such device comprises: a smooth hose configured to be inserted into the opening of the hatch of the storage hold cover of the ship; a folding hose placed above the smooth hose and configured to absorb the movements of the bulk carrier relative to the device; an upper flange for fastening the device to the free end of the nozzle of the ship loader; and a lower flange configured to connect the device to the hatch opening of the storage hold cover of the ship. The disclosure also includes a method of loading bulk carriers using the device.

Embodiments, including apparatuses, systems and methods, for automatically attaching and detaching seismic devices to a deployment cable, including a plurality of autonomous seismic nodes. A node installation system may include a moveable node carrier coupled to a cable detection device and a node attachment device that is configured to move a direct attachment mechanism on a node into a locking or closed position about the deployment cable. In an embodiment for retrieval and/or detachment operations, the system may also be configured to automatically detect the position of a node and remove the node from the deployment line by actuating the direct attachment mechanism into an open or unlocked position. Other devices besides a node may be attached and detached from the deployment line if they are coupled to one or more direct attachment mechanisms.
