Baot New Chain Hoist Outlet Customized 1t 2t 3t 5t VD Type Manual Chain Hoist
Core Technical Advantages: Precision Engineering Drives Reliability
- Load-Bearing Chain: Adopts heat-treated manganese steel chain (grade 80) with high tensile strength (minimum breaking load ≥ 8 times the rated load) and excellent wear resistance. The surface is galvanized or nickel-plated to prevent corrosion, ensuring long-term use in humid or dusty environments.
- Gear System: Equipped with high-precision hardened alloy steel gears (hardness up to HRC 60) processed by CNC grinding. The optimized tooth profile design reduces friction loss, achieving a mechanical efficiency of over 90% and ensuring smooth hand operation with minimal pulling force (≤ 360N for standard models).
- Shell & Frame: Made of low-alloy high-strength cast iron (QT450-10) or lightweight aluminum alloy (for portable models). The sealed structure effectively isolates dust, water droplets, and debris, protecting internal components from damage.
- Overload Protection Clutch: Built-in automatic overload protection. When the load exceeds 110% of the rated capacity, the clutch slips to prevent gear or chain damage, avoiding safety accidents caused by overloading.
- Self-Locking Brake System: Adopts a multi-disc friction brake with self-locking function. It can instantly lock the load in any position (even if the hand chain is released suddenly), ensuring no slippage during lifting or suspension, and maintaining stable load holding for a long time.
- Chain Anti-Derailment Guide: The chain guide groove is designed with a curved arc structure, which guides the chain to run smoothly and prevents derailment or jamming during operation—especially critical for horizontal pulling operations.
Wide Application Scenarios
- Construction Sites: Suitable for lifting steel structures, building materials, and equipment in high-rise or narrow construction spaces (e.g., indoor beam installation, facade decoration).
- Manufacturing Workshops: Used for assembling heavy machinery, transferring molds, and maintaining production lines—its compact design (minimum headroom ≤ 300mm) fits low-ceiling workshops.
- Warehousing & Logistics: Facilitates loading/unloading of goods in warehouses, container yards, or freight terminals; compatible with I-beam rails for horizontal movement.
- Outdoor Emergency Rescue: Portable models (≤ 3T) are lightweight and easy to carry, applicable to power repair, bridge maintenance, and disaster relief operations (resistant to dust, moisture, and short-term rain).
VD Type Hand Chain Hoist: The Perfect Integration of Precision Manufacturing and Safety Performance
As a core equipment in light and medium-duty lifting operations, the VD type hand chain hoist stands out in the industry with its advanced manufacturing technology, reliable safety performance, and wide adaptability. Designed for efficient load lifting, lowering, and horizontal pulling in limited spaces, it has become an indispensable tool in construction, manufacturing, warehousing, and emergency rescue fields.
The VD type hand chain hoist adheres to international standards (ISO 7758, CE certification) and undergoes strict quality testing (load testing, fatigue testing, environmental adaptability testing) before leaving the factory. It not only meets the high requirements of modern industrial production for efficiency and safety but also provides customized solutions (e.g., special chain materials, extended lifting height) to meet specific customer needs.
