| Structure & Material |
|
Centered on heavy-load safety + labor-saving durability + power-free universality, the YD30-013 Series HSZ Type Chain Block is optimized for power-free heavy-load lifting scenarios.
- Significant Labor-Saving Effect: Transmission resistance reduced by 30%, lifting efficiency increased by 25%.
- Less Wear: Bearings evenly distribute radial force, reducing wear by 40% and extending service life to 1.5 times ordinary products.
- Strong Load-Bearing Capacity: Breaking strength much higher than ordinary chains.
- Excellent Rust Resistance: Double rust-proof treatment of hot-dip galvanizing + passivation.
- Smooth Meshing: Chain pitch accuracy ≤0.1mm for precise sprocket matching.
- Brake locks instantly when hand chain is released, preventing heavy object from falling.
- Brake system passes 1,000 heavy-load start-stop tests without performance deterioration.
- Anti-Detachment Hook: Automatically resetting safety latches with opening angle ≤60°.
- Lightweight Design: 0.5T model weighs only 8kg; 20T model features modular split design for easy transport.
Scenario Requirement: Lifting a 5T machine spindle out of equipment cavity (2.5m height) during power outage in narrow workspace.
Result: Reduces operators by 70%, shortens lifting time from 1 hour to 20 minutes.
Scenario Requirement: Hoisting 8T steel bundle to 10m-high platform at power-free construction site.
Result: Reduces hoisting cost by 80%, works continuously for 1 month in dusty environments.
Scenario Requirement: Moving 15T shelf in warehouse; lifting 5T vehicle in outdoor rescue.
Result: Increases warehouse efficiency by 80%; completes vehicle rescue in 30 minutes without power.
A1: Choose based on load, height, and scenario:
- Select model with rated load 20% higher than actual load
- Models 0.5T-1.5T have 2.5m lift; 2T-20T have 3m lift
- Prioritize galvanized chain models for outdoor use
A2: Usually operation or maintenance issue:
- For chain entanglement: Pull hand chain slowly in reverse direction
- For insufficient lubrication: Add lithium-based grease (Model Li-2)
A3: Adjust brake clearance:
- Loosen brake spring fixing nut
- Rotate adjustment bolt clockwise (1/4 turn each time)
- Replace brake pad if wear ≥1mm
A4: No, with proper preparations:
- Grade 80 alloy chains maintain toughness at -25℃
- Brake grease is low-temperature type resistant to -30℃
- Preheat components by pulling hand chain empty 10-15 times
