With the rapid development of smart manufacturing and e-commerce logistics, the intelligent upgrade of warehousing systems has become the core battlefield for enterprises to reduce costs and increase efficiency. However, after introducing advanced equipment such as AGV, three-dimensional shelves, and WMS systems, many companies still face the bottleneck of the "last mile" - how to efficiently complete the high-frequency and high-precision transfer of goods from the storage area to the loading and unloading area, production line, or transport vehicle. Traditional bridge cranes are limited by the structure of the factory building, full-gantry cranes require a large area of ground track, and manual forklifts have problems such as low efficiency and many safety hazards. In this context, semi-gantry cranes have become the key equipment to solve the problem of the "last mile" of warehousing and logistics with their unique structural design and intelligent capabilities.
As a leading brand of domestic high-end material handling equipment, Jinghe Crane has been deeply engaged in the research and development and manufacturing of semi-gantry cranes, with "space adaptation, intelligent collaboration, and full reliability" as the core, providing global customers with one-stop intelligent handling solutions from hardware to software.
Semi-gantry crane: technological innovation that breaks through the boundaries of space and efficiency
①. Structural innovation: small space achieves great results
The iconic design of the semi-gantry crane lies in the single-sided rigid outrigger + track beam hybrid support structure. Unlike the traditional full-gantry crane that requires double-sided ground tracks, one end of it is fixed to the ground track through the outrigger, and the other end is directly erected on the plant column or concrete platform, which greatly reduces the ground area occupied (saving more than 30% of space). This design is particularly suitable for the following scenarios:
Old warehouse renovation: the handling system can be upgraded without large-scale demolition and reconstruction;
High-density storage area: seamless connection between three-dimensional shelves and handling equipment in a limited space;
Cross-region transfer node: connect the storage area with the loading and unloading platform and production line to form a coherent moving line.
Jinghe semi-gantry crane further optimizes the structural mechanics model, adopts high-strength lightweight steel and modular prefabricated components, so that the maximum span can reach 50 meters, the lifting height exceeds 30 meters, and the deadweight is reduced by 15%, significantly reducing the load pressure on the building structure, and adapting to more complex scenarios.
②.Intelligent drive: millimeter-level precision enables automation
The core demands of intelligent warehousing are "precision" and "unmanned". Jinghe semi-gantry crane is equipped with self-developed variable frequency control system and AI positioning algorithm, achieving three major breakthroughs:
Precise stop control: the positioning error of the hoist is ≤±1mm, which meets the requirements of non-destructive handling of precision instruments and electronic components.
Speed adaptation: automatically adjust the lifting and walking speed according to the load weight, and improve efficiency by 40%.
Unmanned operation: directly connect with WMS and MES systems through the Internet of Things interface, receive instructions to automatically execute tasks such as warehousing, picking, and loading, and reduce manual intervention.
③. All-round adaptation: from standardization to high customization
In order to cope with diversified warehousing needs, Jinghe provides a flexible design of "basic functions + on-demand expansion":
Wide load coverage: 5-ton to 200-ton models are available, suitable for handling all categories of small packages to heavy machinery;
Environmental customization: special models such as explosion-proof (chemical warehouse), clean type (pharmaceutical warehouse), low-temperature type (cold chain warehouse);
Flexible switching of lifting equipment: magnetic suction cups, vacuum grippers, container lifting equipment, etc., can be quickly replaced to meet the needs of multi-form cargo handling.
Scenario practice: semi-gantry cranes open up key links in warehousing
①. "Goods to people" picking in stereoscopic warehouses
In automated stereoscopic warehouses, semi-gantry cranes and stackers work together: stackers are responsible for the storage and retrieval of vertical storage locations, while semi-gantry cranes are responsible for the horizontal transfer of goods to the picking area. In the solution designed by Jinghe for an auto parts company, the semi-gantry crane automatically identifies the goods through barcode scanning and accurately transfers them to the AGV docking point. No human intervention is required throughout the process, and the picking efficiency is increased by 200%.
②. "Zero waiting" for platform loading and unloading
In traditional warehousing, it is normal for trucks to queue up for loading and unloading. Jinghe's semi-gantry crane can obtain vehicle arrival information in advance through the intelligent scheduling system, and transport the goods to be loaded to the platform buffer in advance. When the truck arrives, the crane directly completes the loading, and the vehicle's stay time is shortened by 70%. After a logistics hub adopted this solution, the platform utilization rate increased from 60% to 95%.
③. "Instant feeding" on the production line
In the intelligent manufacturing workshop, the semi-gantry crane has become the core carrier of JIT (just-in-time) feeding. By connecting with the enterprise's MES system, Jinghe equipment can obtain production plans in real time and automatically transport raw materials from the stereoscopic warehouse to the production line buffer area. After the introduction of a factory of a home appliance giant, the waiting time of the production line was reduced by 90%, and the inventory turnover rate increased by 50%.
Jinghe Case: Semi-gantry crane reshapes the industry benchmark
Case 1: Intelligent upgrade of bonded warehouse in Tanzania International Port
Pain point: The efficiency of cargo transfer across floors in bonded warehouse is low, and labor costs account for more than 40%.
Jinghe Solution: Deploy 3 semi-gantry cranes with a span of 35 meters, connect the stereoscopic warehouse with the loading and unloading area, and integrate the customs supervision system to realize the automation of "inspection-sorting-exit".
Results: The average daily handling volume of goods increased from 8,000 pieces to 25,000 pieces, and the customs clearance time was shortened by 50%, which was rated as a "smart port demonstration project".
Case 2: Construction of unmanned warehouse in new energy battery industry
Pain point: The battery module is heavy (2 tons per tray), the handling accuracy requirement is high (±2mm), and the safety hazards of manual operation are prominent.
Jinghe Solution: Customized explosion-proof semi-gantry crane + vacuum suction cup hoist, linked with AGV to complete the unmanned process from raw material storage to finished product loading.
Results: Handling efficiency increased by 120%, safety accidents were reduced to zero, and helped customers win the title of "Lighthouse Factory".
