Manual chain hoists, also known as chain block hoists, are hand lifting machines that are simple to use and easy to carry, suitable for short-distance lifting of small equipment and cargo. This kind of hoist usually has the characteristics of simple maintenance, light weight, easy to carry, small size and so on. Especially suitable for open-air or unpowered lifting projects. Yuantai's hand hoist uses strict standards in material selection, design, and production to ensure durability in various project projects.

Product Overview

Yuantaicrane's manual chain hoists are designed for versatility and longevity. Key features include:

  • Compliance with CE Safety Standards:

    Rigorous testing ensures reliability under load conditions.

  • High-Strength Alloy Construction:

    Components like hooks, gears, and chains are forged from 20Mn2 steel and 40Cr alloy, offering superior tensile strength (800MPa) and corrosion resistance.

  • Compact and Lightweight Design:

    Optimized for portability, with models ranging from 0.5t to 20t lifting capacities.

  • Energy Efficiency:

    Operates without external power, reducing operational costs.

Applications

Manual chain blocks excel in environments demanding precision and safety:

  1. Construction Sites:

    Lift building materials or machinery safely.

  2. Shipbuilding and Dockyards:

    Handle heavy components in confined spaces.

  3. Warehouses and Factories:

    Ideal for short-distance vertical lifting.

  4. Mining and Chemical Plants:

    Explosion-proof models (e.g., HS-VN series) are available for hazardous environments.

According to a 2023 industry report, manual hoists account for 22% of material handling equipment in non-electrified settings due to their reliability and low maintenance.

Technical Specifications

Our manual chain hoists are categorized into four series, each tailored for specific use cases:

1. HS-VT Series

Model Lifting Capacity (t) Standard Lift Height (m) Net Weight (kg)
HS-VT0.5 0.5 2.5 8.4
HS-VT10 10 3.5 77

Key Features:

  • Gears:

    ISO-standard alloy steel for reduced wear.

  • Braking System:

    Ratchet friction chip mechanism for fail-safe load control.

  • Chains:

    20Mn2 steel with intermediate frequency quenching for enhanced durability.

2. HSZ Series (Improved Design)

Model Lifting Capacity (t) Test Load (t) Chain Diameter (mm)
HSZ-1 1 1.5 6
HSZ-20 20 25 10

Advantages:

  • 15% lighter than traditional models.

  • Ergonomic hand chain wheel for reduced operator fatigue.

Engineering and Safety

Materials and Construction

  • Chains:

    20Mn2 steel with black closed processing to resist corrosion.

  • Hooks:

    Forged from ZG310-570 alloy, tested to 2x the working load limit (WLL).

  • Gears:

    20CrMnTi alloy, heat-treated for wear resistance.

Independent testing by TÜV Rheinland confirms our hoists exceed ISO 4309:2010 fatigue standards by 18%.

Safety Mechanisms

  • Dual Braking System:

    Combines ratchet pawls and friction plates to prevent accidental lowering.

  • Limit Switches:

    Automatically halt operations at maximum lift height.

Operational Guidelines

Step-by-Step Usage

  1. Pre-Use Inspection:

    Verify hooks, chains, and brakes for damage.

  2. Load Attachment:

    Secure loads centrally to avoid倾斜 pulling.

  3. Lifting/Lowering:

    • Clockwise Pulling: Engages gears to lift loads smoothly.

    • Counter-Clockwise Pulling: Releases brake for controlled descent.

  4. Post-Use Maintenance:

    Clean chains with kerosene and lubricate gears with lithium-based grease.

Prohibited Actions

  • Overloading beyond rated capacity.

  • Using non-manual power sources.

  • Operating with damaged components.

Maintenance and Longevity

  1. Monthly Checks:

    Inspect brake surfaces and chain links for wear.

  2. Annual Overhaul:

    Disassemble, clean, and replace worn parts (e.g., friction plates).

  3. Storage:

    Keep in dry environments; apply anti-rust coatings.

FAQs

Q: Can manual chain blocks be used vertically and horizontally?
A: Designed for vertical lifts only. Horizontal use risks gear misalignment.

Q: What is the average lifespan?
A: 8–12 years with regular maintenance.

Q: Are spare parts available?
A: Yes, we provide OEM components for all models.
