- Product Positioning: Designed for light-to-medium heavy-load lifting in narrow spaces without power supply, serving equipment maintenance, pipeline installation, warehouse handling, and outdoor emergency rescue.
- Core Certifications: CE-certified, 1.5x overload tested, 1-year warranty, RoHS compliant eco-friendly coating.
- Structure & Material: T80-grade high-strength chain, bearing-supported sprocket, automatic pawl-ratchet brake, 40Cr forged steel hooks with safety latches.
Optimized for narrow space adaptation, labor-saving efficiency, and safety durability, addressing core pain points of heavy-load lifting in limited spaces.
- Labor-Saving Design: Lever principle amplifies force - 9T model requires only 392N (equivalent to lifting 40kg).
- Small Operating Space: 30°-45° lever swing angle works in spaces ≤500mm wide.
- Smoother Transmission: Bearing-equipped sprocket reduces resistance by 40%, chain guides prevent jamming.
- Rugged Chain: T80-grade chain withstands 1.5x test load, hot-dip galvanized for rust prevention.
- Safe Hooks: 40Cr forged steel hooks endure 13.5T test load without cracks.
- Lightweight Design: 0.25T model weighs only 1.85kg; 9T model at 46kg movable by two people.
- Multi-Scenario Use: Equipment maintenance, pipeline installation (≤15° incline), outdoor rescue.
- Simple Maintenance: Lithium grease every 50 uses; individual component replacement reduces costs.
Scenario: Lift 2T motor in 300mm gap during power outage.
Result: Reduces operators by 75%, lifting time from 1 hour to 15 minutes.
Scenario: Lift 5T steel pipe at 10° incline in ≤600mm space.
Result: 90% cost reduction vs cranes, works in dusty environments for 2 months.
Scenario: Move 8T shelf in 500mm space; rescue 3T vehicle in muddy conditions.
Result: 85% efficiency increase; power-free emergency operation.
A: Consider load (20% higher than actual), space (model size), and operation method (single/two-person).
A: Usually chain deviation or insufficient lubrication - reset chain or add lithium grease.
A: Adjust brake clearance by rotating adjustment bolt clockwise in 1/4 turns.
A: Chain remains tough; preheat by empty lever operation to melt lubricant before load use.
