Project Background
Client: A small industrial equipment manufacturing factory in Thailand.
Core Challenges:
Outdoor Material Handling: Relied on rented mobile cranes, causing delays (avg. 3-hour wait per lift) and high costs ($350/day).
Space Constraints: Limited yard space blocked fixed crane installation.
Safety Risks: Manual lifting of heavy gearboxes (1.5–2.8T) in high humidity led to frequent worker injuries.
Solution:
Sinoko crane has specially equipped a 3 ton portable gantry crane with all-terrain mobility for the client. Key specifications:
Feature | Specification | Purpose |
Capacity | 3ton | Lifts machinery parts & raw materials |
Span | 5m | Fits narrow pathways between storage |
Lifting Height | 5m | Clears trucks & containers |
Hoist Type | Electric Chain Hoist | Shock-free lifting |
Power Supply | 380V/50Hz/3Ph | Matches Thai grid standards |
Wheels | 4x Braked Swivel Casters | 360° movement on gravel/concrete |
Why Sinoko This Portable Gantry Crane Stands Out
Adaptive Mobility
All-Terrain Casters:
Heavy-duty polyurethane wheels (Ø200mm) with dual-locking brakes handle slopes up to 3° and resist dust/moisture (IP54-rated).
Quick Assembly:
Modular design allows disassembly in 20 minutes (max part weight: 85kg), enabling storage in tight spaces.
Tropical-Proof Engineering
Monsoon Resilience:
Powder-coated steel frame resists corrosion in 80% humidity. Hoist motor includes thermal protection for 40°C heat.
Anti-Sway Control:
VFD-regulated lifting (0–8 m/min) enables ±1mm precision—critical for delicate parts like hydraulic valves.
Safety & Versatility
Fail-Safes: Overload limiter (cuts power at 110% capacity) + dual limit switches.
"QuickSwap" Attachments: Interchangeable hoist system works with electric chains, manual blocks, or monorail trolleys—switchable in 8 minutes.
Smooth Installation & Training
The portable gantry crane model Sinoko is relatively easy to install and operate, so it takes very little time. Here is the detailed process:
Phase 1: Site Prep
Challenge | Solution |
Uneven gravel terrain | Laser-leveled steel plates for caster stability |
Voltage spikes (350–410V) | Installed surge protectors (±15% buffer) |
Phase 2: Hands-On Commissioning
Load Testing:
3.3T test (110% capacity) with <2mm frame deflection.
Slope stability check on 2.8° incline (<0.5m drift after braking).
Thai-Language Training:
Live demos for load balancing + VR modules for emergency procedures.
Real-World Results
This small gantry crane has brought great convenience to the customers. The following data represent the feedback from the customers to Sinoko crane:
Operational Gains:
Space Efficiency: Yard utilization jumped from 60% → 92%.
ROI: 5-month payback via rental savings.
Flexibility: One crane now serves 3 zones: assembly line, storage yard, loading dock.
Where This Small Gantry Crane Excels in Thailand
Industry | Use Case | Why It Works |
Equipment Repair | Motor swaps in repair pits | 5m height clears service trenches |
Warehouse Loading | Container unloading | Casters move between trucks in minutes |
Construction | Moving rebar in tight sites | 5m span fits alleyways |
Agriculture | Installing pump systems | Quick assembly in remote fields |
Client’s Verdict:
The wheels of this crane enable us to avoid the water accumulation caused by the monsoon, and the detachable hook can meet various operational needs. We no longer need to rent other cranes, and we have increased our production by 40%." - The on-site manager of the Chiang Mai factory.
