General Basic Parameters
Parameter Category Specific Description
Product Positioning Designed for power-free, high-altitude heavy-load lifting scenarios, serving fields such as factory workshop equipment maintenance, construction material hoisting, warehouse cargo handling, and outdoor rescue. 8 models cover a load range of 0.5T-20T, balancing lightweight portability and industrial-grade load-bearing capacity.
Core Features
  • Power-Free Operation: No external power supply required; manually pull the hand chain for lifting, suitable for power-free scenarios.
  • Customization Service: Supports OEM customization and personalized function adjustments.
  • International Standards: Complies with international safety standards, with all models passing overload tests (1.5 times rated load).
Structure & Material
  • Chain System: Grade 80 high-strength alloy chain with hot-dip galvanized surface for rust prevention.
  • Transmission Mechanism: Double-bearing design with precision gear set, transmission efficiency ≥90%.
  • Braking System: Built-in ratchet-pawl brake with braking torque ≥3 times rated load torque.
  • Hook Assembly: 40Cr forged steel hooks with automatically resetting safety latches.
Product Details

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.

Double-Bearing + High-Strength Chain, Effortless Heavy-Load Lifting
Double-Bearing Transmission, Excellent Efficiency and Durability
  • 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.
Grade 80 Alloy Chain, Rugged, Rust-Proof and Non-Jamming
  • 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.
Multiple Safety Protections, No Risks in Heavy-Load Operations
"Lock-on-Release" Brake, More Reliable Anti-Fall Protection
  • 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 + Compact Structure, Safe and Portable
  • 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.
Application Scenarios
Factory Workshop Equipment Maintenance (Core Scenario: Models 0.5T-5T)

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.

Construction Material Hoisting (Scenario 2: Models 3T-10T)

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.

Warehouse Cargo Handling & Outdoor Rescue (Scenario 3: Models 0.5T-20T)

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.

Frequently Asked Questions
Q1: How to choose the right model based on actual needs?

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
Q2: The chain jams during lifting. Is this a fault? How to solve it?

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)
Q3: After long-term use, the braking effect decreases. How to adjust it?

A3: Adjust brake clearance:

  • Loosen brake spring fixing nut
  • Rotate adjustment bolt clockwise (1/4 turn each time)
  • Replace brake pad if wear ≥1mm
Q4: When used outdoors at low temperatures (-25℃), will the chain become brittle and the brake fail?

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
