Wood chips and coal are important raw materials and fuels for paper production. For paper company customers with multiple bulk material loading and unloading needs, seeking a compatible machine model that can be used for both wood chips and coal unloading will not only bring convenience and practicality to the company's bulk material loading and unloading operations, but also help save the customer's dock space and improve dock utilization.

      For customer needs, Rainbow has developed a new type of bridge type grab unloader for the customer. It has a rated unloading capacity of 1000 tons per hour and can be equipped with various types of grabs according to the working conditions to meet the needs of different bulk material unloading operations, such as wood chips and coal, etc. It is the first bridge grapple ship unloader for both wood chips and coal in China.

      In terms of the overall structure of the equipment, GENMA dual-purpose bridge grab ship unloader has made innovative improvements to the structure and trolley drive form according to the characteristics of inland waterway use, and after the improvement, the weight of the machine is more than 12% lower than the conventional model, the driving power is more than 30% lower. The machine has the advantages of light weight and energy consumption, and can meet the ship unloading operation of 1000-7000DWT vessels, covering a comprehensive range of bulk material unloading solutions.

      As a product that combines wood chip and coal unloading functions, although "dual-purpose" is the biggest label of this bridge grab unloader, in fact, from the outside to the inside, "high performance" is the summary of its charm.

      · Automated control system grapple unloading more efficient

      The lifting, opening and closing and trolley traction mechanism is the most important working mechanism of the ship unloader, which is responsible for the lifting, opening and closing operation of the grab and the lateral displacement of the trolley, and is closely related to the operation efficiency of the equipment.

      GENMA dual-purpose bridge grab ship unloader adopts GENMA self-developed self-propelled trolley system and advanced AC frequency control system, the equipment lifting, opening and closing and trolley running mechanism are separately driven, and each mechanism can be steplessly speed-controlled, the overall operation is smooth, responsive, operate easily and high efficiency. At the same time, the control system can also plan the optimal running trajectory of the grab according to the boundary conditions set by the driver, so as to complete the grabbing operation safely and efficiently and greatly reduce the labor intensity of the driver.

      · Unique discharge system More flexible material conveying

      In order to improve the operational stability and durability of the machine and to increase the productivity of the machine, GENMA designers have innovated and designed a unique discharge system for the machine.

      Different from the common hopper, GENMA dual-purpose bridge grab ship unloader has an innovative design of inverted "Y" shaped diverter hopper under the hopper. With the splitting device under the hopper, the equipment can feed the two belts on the quay corridor separately and evenly, thus effectively avoiding material accumulation and improving discharge efficiency, while effectively reducing the impact of the material on the downstream conveyor and extending the service life of the belt conveyor.

      It is worth mentioning that the GENMA dual-purpose bridge grab ship unloader can also be adapted to the two conveyor belts on the wharf by switching between different discharge ports according to the different materials as needed.

      · Advanced dust removal system equipment operation more environmentally friendly

      In terms of environmental protection, the equipment is equipped with an advanced dust removal solution.

      GENMA dual-purpose bridge grab ship unloader is equipped with dust suppression devices above the hopper and at each material transfer point. Through the associated program setting of the grab position and dust removal device, the equipment can realize automatic opening of the spray dust removal system for dust removal when the grab is in the hopper area. This dust removal solution can not only control the dust during the ship unloading operation to the maximum extent, but also save water resources and achieve the comprehensive purpose of resource saving and environment friendly.

      As a material handling solution brand of Rainbow Heavy Machineries, GENMA always adheres to the brand positioning of "high-end, high customization and high performance" to provide customers with valuable products and series solutions. In the future, GENMA will adhere to the customer demand-oriented, constantly improve the brand's technological innovation ability, and continue to create higher value for customers.
