Product Definition
Single Beam KBK Crane (KBK-I)
Consists of a cold-rolled KBK-specific track as the main beam, paired with electric/manual chain hoists, rated load 80 kg – 1,250 kg.
Double Beam KBK Crane (KBK-II)
Uses two parallel KBK tracks as the main beams, with a more stable bridge structure. Rated load 1,000 kg – 3,200 kg, can integrate larger power walking drives.
Core Advantages of KBK Crane System
- Modular Design: Standardized components (track, lifting points, walking mechanism) for quick assembly, supporting system expansion and reorganization.
- Flexible Layout: Tracks can be arranged in straight, curved, or branching lines, adapting to complex workshop layouts.
- Lightweight Structure: Aluminum alloy tracks reduce the factory’s bearing requirements, cutting installation costs by over 30%.
- Precise Positioning: Manual/electric push/pull force ≤ 1 kg per 100 kg load, achieving millimeter-level fine adjustment (±1 mm).
- Low-Cost Operation and Maintenance: Maintenance-free design, easy module replacement, with minimal downtime.
Single Beam KBK Crane vs. Double Beam KBK Crane
| Dimensions | Single Beam KBK Crane | Double Beam KBK Crane |
| Structure | Single main beam + electric hoist | Double main beams + trolley lifting mechanism |
| Rated Load | 0.125-2 tons (economical light load option) | 1-5 tons (heavy-duty, high-efficiency option) |
| Applicable Scenarios | Small parts assembly lines, machine tool workstation delivery, maintenance areas | Frequent lifting production lines, warehouse logistics, medium-sized equipment installation |
| Space Adaptability | Low headroom requirement, compact design | Requires more vertical space, stronger span support |
| Positioning Accuracy | ★★★★☆ (small hoist swing) | ★★★★★ (double beam structure is more stable with excellent swing suppression) |
| Cost Composition | 30% lower investment cost, cost-effective choice | Higher initial investment, but better long-term cost efficiency for high-frequency use |
| Typical Application Cases | Automotive parts production line, electronics workshop material handling | Mold workshop, packaging center, metal processing area |
Industry Application Solutions
Intelligent Manufacturing Sector
- Single Beam: Precision instrument assembly lines (under 1 ton material airborne transportation)
- Double Beam: Stamping machine mold replacement (3-ton level quick positioning)
Warehouse Logistics Center
- Single Beam: Light goods transfer in picking areas
- Double Beam: Palletized cargo loading and unloading (with vacuum suction cups/clamps)
New Energy Production Line
- Double Beam: Battery module lifting (anti-sway control and precise docking)
Selection Recommendations:
Choose Single Beam: If the budget is limited, load ≤ 2 tons, and space is compact.
Choose Double Beam: For high-frequency lifting, load ≥ 3 tons, and high-precision requirements.
