Description
Technical Field
[0001] The utility model belongs to the field of warehousing and freight equipment, and in particular relates to a transfer device for extra-long goods. Background Art
[0002] Warehouse cargo transshipment typically includes two stages: intra-warehouse transshipment and transshipment from the warehouse to the railway platform. Warehouse-to-railway platform transshipment refers to the use of vehicles to transport goods from the warehouse to the railway station and then onto flatbed open trucks, and vice versa. Intra-warehouse transshipment involves unloading goods from vehicles and transporting them to a designated warehouse within the warehouse by manpower or vehicle, and vice versa. Intra-warehouse transshipment is subject to many constraints imposed by warehouse (or tunnel) conditions, especially when transshipping extra-long equipment. When loading and unloading operations are required, the warehouse's operating space is limited, and large lifting equipment cannot be deployed. Multiple forklifts can be used in conjunction, but this coordination is difficult. Forklift operations are also limited by operating space and are not suitable for goods that require high stability. In these cases, the extra-long equipment can only be lifted manually onto a dedicated transport platform, which is then towed by a powered tractor to achieve transshipment. Manual unloading is labor-intensive and inefficient. Utility Model Content
