Project Background
Client: Tier-1 automotive parts supplier in Monterrey, Mexico, specializing in engine block machining.
Core Challenges:
Manual Handling Risks: Workers lifted 1.5–2.8T engine blocks using chain hoists, causing 15% surface scratches and 3 monthly injuries.
Space Constraints: 120m² assembly cell with robotic arms left zero floor space for traditional cranes.
Grid Instability: Voltage fluctuations (440V ±10%) disrupted existing equipment.
Solution:
Deploy Sinoko 3T European Jib Crane with space-optimized design and adaptive controls.
| Parameter | Specification | Client Value |
| Capacity | 3 tons | Handles 95% of engine blocks |
| Arm Length | 4.5 meters | 360° coverage in 6m diameter cell |
| Lifting Height | 4 meters | Clears 3.5m robotic arms |
| Rotation | 270° manual / 360° motorized | Avoids fixed obstacles |
| Hoist Type | VVVF Electric Chain Hoist | ±5mm precision positioning |
| Control | Pendant + Wireless Remote | Operator mobility in tight spaces |
Sinoko 3T Jib Crane: Key Features
A. Space-Optimized Engineering
Zero-Footprint Base: Cement-poured foundation (1.4m³) absorbs seismic forces (Zone 2 compliance) without floor reinforcements .
Low-Profile Boom: 320mm girder depth (vs. industry 450mm) enables 18% more clearance under low ceilings .
B. Precision Handling
VVVF Hoist Control: Acceleration/deceleration at 0.5 m/s² eliminates load sway during engine block transfers .
Dual Braking System: Primary electromagnetic brake + mechanical backup prevents drops during voltage spikes .
C. Industrial Resilience
IP54-Rated Components: Resists metal dust and coolant splashes in machining environments .
Voltage Tolerance: Handles 440V ±15% fluctuations via built-in stabilizers .
Implementation: Fast-Track Deployment
Phase 1: Site Prep (72 Hours)
Laser Leveling: Achieved ≤2mm foundation flatness for column stability .
Grid Hardening: Installed surge protectors at junction boxes (NOM-029-STPS compliant) .
Phase 2: Crane Integration
Modular Assembly: Pre-assembled boom and hoist mounted in 6 hours (minimizing production downtime) .
Validation Testing:
125% Load Test: Lifted 3.75T with ≤2° column deflection .
10,000-Cycle Sim: Validated A4 duty class endurance (150 lifts/day) .
Phase 3: Operator Training
Spanish VR Modules: Simulated collision avoidance in confined cells .
NOM-029 Safety Drills: Lockout/tagout procedures and emergency load lowering .
Quantifiable Results
Operational Transformation:
| Metric | Pre-Install | Post-Install | Improvement |
| Engine Block Damage | 15% | 0.2% | 98.7% reduction |
| Handling Time/Part | 8.5 minutes | 3.2 minutes | 62% faster |
| Monthly Worker Injuries | 3 | 0 | 100% safer |
| Energy Consumption | 9.2 kWh | 4.1 kWh | 55% savings |
Strategic Impact:
ROI: 11 months via reduced scrap and OSHA fines.
Scalability: Client ordered 6 additional cranes for stamping lines.
Cross-Industry Applications
| Industry | Use Case | Sinoko Adaptation |
| Automotive | Engine block positioning | ±5mm VVVF precision for mating heads |
| Aerospace | Turbine blade handling | IP54 protection against composite dust |
| Food Processing | Silo ingredient loading | Stainless steel hoist (FDA-compliant) |
| Warehousing | Machinery relocation | 270° manual rotation in narrow aisles |
