3‑Ton VFD Electric Winch for Ghana Sawmill Log‑Pulling Project
Overview
Zhifang delivered 3 sets of customized JM‑series 3‑ton variable‑frequency electric winch for a local sawmill in Ghana, Africa. The equipment is dedicated to heavy‑log dragging and material handling under harsh outdoor dusty site conditions. Fast delivery and tailored control logic helped the client improve log‑processing efficiency at their timber production plant.

Project Info
Destination: Ghana, West Africa
Equipment: JM‑series 3t VFD electric winch
Working duty: A3
Production lead‑time: 15 working days
Application: Heavy log pulling in saw‑mill, outdoor dusty working environment
Client Background
The end‑user runs a local timber processing & sawmill factory. Large‑size raw logs need to be dragged onto processing platforms continuously. Standard fixed‑speed winches cannot meet variable‑load pulling requirements. Key pain points:
Log weight varies greatly, requiring adjustable pulling speed;
Open‑air workshop with heavy dust, high ambient temperature;
Demand stable torque output under frequent start‑stop operation.
Our engineering team recommended a VFD‑controlled JM slow‑speed electric winch instead of general‑purpose lifting winch, optimized for traction‑oriented working conditions rather than vertical hoisting.
Key Technical Specifications
Item | Parameter |
Model | JM Series Electric Winch |
Rated Pulling Force | 30 kN (3 Ton) |
Wire Rope Length | 30 m |
Working Class | A3 |
Power Supply | 3‑Phase 400V 50Hz |
Control Mode | VFD variable‑frequency speed regulation (potentiometer speed adjustment) |

Customization Highlights
Variable‑frequency speed control: Operators continuously adjust pulling speed according to log weight, realizing smooth startup & stop, avoiding cable shock load. Greatly improves operation safety for log‑dragging work.
Dust‑resistant design for tropical outdoor site: Motor and control cabinet adopt enhanced dust‑proof treatment, adapting to Ghana’s high‑temperature, heavy‑dust open‑air sawmill environment.
Traction‑optimized control logic: Parameter tuning focuses on constant‑torque pulling performance, suitable for horizontal dragging instead of vertical lifting.
Complete export package: Full export‑grade wooden case packing, complete set of English documents: operation manual, test report, BOM list, drawing files.
Shipment & After‑sales
Production and full‑load factory acceptance test were completed within 20 working days. The unit was packed in fumigated export wooden cases and delivered under FCA trade terms. We provide 12‑month warranty period, together with remote online technical guidance for installation, commissioning and daily troubleshooting.
Project Value & Customer Feedback
After equipment put into operation:
Realized stepless speed adjustment for log dragging; operation becomes safer and more stable;
Reduced wire‑rope impact wear, extended service life of key components;
Helped the saw‑mill boost throughput of raw timber feeding. This case proves our capability to deliver cost‑effective customized winch solutions for Africa forestry & timber‑processing industry.
