  A rope grab is a loading device, which is controlled mechanically via a rope system. Thus, the width of loader buckets’ opening can be regulated with a wire rope if neessary. After lowering open buckets to the cargo consisting of mostly bulk materials, the rope is released and loader buckets’ are lowered by means of gravity. One can fill the buckets with the load and close them simultaneously simply by slowly raising the buckets and using the closing rope. Rope grab's work is based on a cable principle or the principle of force distribution across the pulleys. This means that there are slight differences between one rope grabs, two rope grabs, three rope grabs and four rope grabs. The particular distribution of ropes in the form of closing ropes and holding ropes depends on the crane used herein. The advantage of a mechanical rope grab is that no current or feed lines are needed for the operation of hydraulic power units. Wide range of such rope grabs can be found on the website of Orts-GmbH located in Schleswig-Holstein’s Sereetz near Lübeck. The company develops and produces grabs and beams used in cargo handling operations for more than 40 years.

  Dredger grab is an attachment for loading and unloading of various materials. Design of such grabs differs significantly depending on their purpose. If it is designed for handling bulk materials, then dredger grab consists of two parts, which constitute a closed container for receiving bulk material. Dredger grab can also have multiple teeth instead of buckets designed to accommodate bulky items, such as recycled materials. Another variation is a circular shape machine designed for grabbing tree trunks and some wooden hubs. As a rule, a grab is connected to the hydraulic system of the dredger and is opened or closed by means of hydraulic cylinders. Orts-GmbH located in Sereetz near Lübeck in Schleswig-Holstein manufactures and sells different modifications of dredger grabs. Orts-GmbH is present at the market since 1972 and is engaged in the development and design of handling systems. In 1985 it began producing its own devices. The product portfolio of the company includes different grabs, as well as crane equipment, slewing gears and beams.

  Electro hydraulic grabs are attachments to cable cranes that open and close their buckets using their own drives. Electro hydraulic grab is equipped with electric motor situated above the buckets; it supplies power to the hydraulic pump. Hydraulic pump brings hydraulic cylinder into action forcing grab buckets to open and close. Power is supplied to the electro hydraulic grab via a power cord that is situated at the crane jig. Electro hydraulic grabs are designed and produced by Orts-GmbH. The company located in Sereetz near Lübeck in Schleswig-Holstein is engaged in the development and production of grabs, crane equipment and load beams. Production of Orts-GmbH is used in dry bulk handling. Electro hydraulic control systems require power supply only and do not need expensive hydraulic lines from the crane to the bucket. Ideal for cable cranes in ports or other transshipment points for unloading ships or wagons in areas where it is impossible or very difficult to use hydraulic tracking.

  A radio controlled grab is a crane attachment that is operated independently of power cables or hydraulic lines; it is completely self-sufficient and is operated via a remote control. Thus, a radio controlled grab can be used on any cable crane, since an external power supply is not necessary. The grab’s buckets are situated above a diesel engine, which provides the power needed to drive the hydraulic pump, with the help of which hydraulic cylinders are moved to the buckets. The crane operator has to send command to move the buckets via a remote control. A radio controlled grab is used in crane systems, which have no jig hydraulic or electrical supply or in areas with insufficient energy supply. Orts-GmbH develops and manufactures radio controlled diesel and hydraulic grabs for worldwide use. The company is headquartered in Sereetz, situated near Lübeck. It designs crane equipment, dradgers and load beams for more than thirty years. 90% of Orts’ products such as the radio controlled diesel grab are exported abroad.

  Orts GmbH offers such products as diesel hydraulic grabs, hydraulic-, electro hydraulic and mechanical grabs. The company, based in Schleswig-Holstein’s Sereetz sitauted near Lübeck, designs, develops and manufactures attachments for dredgers and cranes for thirty-two years, offers crane equipment, slewing gears and load beams for heavy loads (up to 100 tons), as well as flat beam frames. The focus of the company is the production of blade grabs that can be use in different application areas. For example, dradger grab with dead weights up to 80 tons. Such heavyweight equipment can be used to expand St. Petersburg’s port. Orts GmbH has built a grab for lifting ship wrecks in the Suez Canal. Their dead weight is 115 tons and traction power - 400 tons. The rope grab produced by Orts GmbH can be used in crane systems of ports and transshipment points located in any corner of the world. Devices manufactured by Orts GmbH always prove their quality - over 3000 of manufactured and delivered blade grabs speak for themselves.

  Dry bulk handling means clearing and loading of cargo ships, as well as loading and unloading of goods delivered by other transport systems, such as railway  system. Specialized dry bulk handling equipment that can move large volumes quickly and effectively is needed for handling dry bulk cargoes. As a rule, dry bulk handling devices can be found on crane equipment. Its jig can unload a ship standing in the port. Different attachment devices are used in crane systems. These are grabs or load beams that are used for unloading, depending on the goods’ type. For example, load beam is used for loading and unloading of container ships and blade grab is used in bulk cleaning. These products belong to the core competencies of Orts-GmbH. Based in Schleswig-Holstein’s Sereetz, the company is specialized in the manufacture of different modifications of grabs, crane equipment, slewing gears and beams for heavy loads (up to 100 tons) that are used in many ports of the world. Since 1971 Orts-GmbH develops and manufactures specialized equipment and handling systems used not only for dry bulk handling.

  A load beam can be found on a cable crane. The load beam is to be understood as a cross beam, which can have longitudinal beams at its ends used for load carrying. An example of this is loading of container ships. Four corners of a containers are lifted and moved down with the help of load beams found on the loading crane. A mechanically operated closure system ensures proper functioning of the crane system. The beam is adjusted to the maximum lifting capacity of the loading crane. Load beams produced by Orts-GmbH have a load capacity of up to 100 tons. The company, based in Lübeck, Schleswig-Holstein’s Sereetz designs and manufactures different beams, as well as rope grabs and dredger grabs. Orts-GmbH always takes into account client’s wishes in the process of beam’s manufacture, as well as beam specifications, as it shall often be designed for a specific load.

  A diesel hydraulic grab is a bucket grab, which does not require power for hydraulic system’s operation. The principle of diesel hydraulic grab’s work is based on the installation of a diesel engine directly above the buckets. Thereby, the charging buckets and the motor form a unit, which is attached to the crane hook. Diesel engine produces electric power needed to operate a hydraulic pump or, in other words, to force hydraulic cylinders to open and close the buckets. So, no supply lines are necessary for its operation. Crane operator can open and close the buckets by a radio control command. The diesel hydraulic grab is used in areas, where only loading cranes and other crane systems with a crane hook, designed only for loads’ lifting or lowering, are applicable. For example, one can manage bulk or recycled materials using an independently operating diesel hydraulic grab only. The following grabs are manufactured by Orts-GmbH located in in Schleswig-Holstein’s Sereetz. This company develops and manufactures such devices as rope grabs and load beams.

  Mechanical grab is an attachment to the cable-mounted crane. As the name suggests, mechanical grab is operated by means of cable systems only and requires no power supply or hydraulic lines. Mechanical grabs have different number of circuit cables and ropes. Their number depends on the crane application peculiarities. Mechanical grab is used for loading and unloading of bulk materials in ports, at industrial plants, as well as in ore smelting and blast furnaces’ operation. It is used in port facilities as well. Here a purely mechanical grab is a great advantage. Options of the mechanical grab can be seen on the website of Orts-GmbH. The company develops and manufactures both mechanically, as well as hydraulically operated grabs with electric and diesel engines. Another focus of Orts-GmbH located in Schleswig-Holstein Sereetz is the production of beams for heavy loads (up to 100 tons), slewing gears and crane equipment.
