Chain Pulley Block – Motorised And Manual

Providing the best construction policy to customers.
Introduction

Manual Chain Pulley Block

A manual chain pulley block is a simple, yet effective lifting device used to lift, lower, or move heavy loads. It consists of a chain, pulley, and hook, operated manually by pulling the chain.

Key Features:

  • Manual Operation: Operated by pulling the chain, no electricity required.
  • Chain: High-strength alloy steel chain, typically with safety factor of 5:1 or higher.
  • Pulley: Grooved wheel with bearings, designed for smooth chain movement.
  • Hook: Forged steel hook with safety latch, attaches to load.

Specifications:

  • Capacity: Typically ranges from 0.5 tons to 10 tons or more.
  • Lifting Height: Standard lifting heights range from 3m to 12m.
  • Chain Size: Depends on capacity, typically 6mm to 10mm diameter.
  • Safety Factor: Typically 5:1 or higher.

Applications:

  • Warehouses: For lifting and moving heavy loads, machinery, or equipment.
  • Construction Sites: For lifting materials, tools, or equipment.
  • Factories: For assembly, maintenance, or repair work.

Standards:

  • IS 3938: Indian Standard for manual chain pulley blocks.
  • FEM: Fédération Européenne de la Manutention (European Federation of Materials Handling) standards.

Required Details:To provide more specific information, please provide the following:

  • 1. Required capacity (tons)
  • 2. Lifting height (meters)
  • 3. Any specific standards or regulations required (e.g., IS, FEM, etc.)
Introduction

Motorized Chain Pulley Block

A motorised chain pulley block is an electrically powered lifting device used to lift, lower, or move heavy loads. It consists of a motor, gear system, chain, and hook.

Key Features:

  • Motorised Operation: Powered by an electric motor, reducing manual effort.
  • Chain: High-strength alloy steel chain, typically with safety factor of 5:1 or higher.
  • Gear System: Reduces motor speed, increases lifting capacity.
  • Hook: Forged steel hook with safety latch, attaches to load.

Specifications:

  • Capacity: Typically ranges from 1 ton to 20 tons or more.
  • Lifting Height: Standard lifting heights range from 3m to 12m.
  • Speed: Typically 4-8 m/min, adjustable.
  • Power Supply: 220V/440V, 3-phase, 50Hz AC.

Applications:

  • Warehouses: For lifting and moving heavy loads, machinery, or equipment.
  • Factories: For assembly, maintenance, or repair work.
  • Construction Sites: For lifting materials, tools, or equipment.

Standards:

  • IS 3938: Indian Standard for manual chain pulley blocks.
  • FEM: Fédération Européenne de la Manutention (European Federation of Materials Handling) standards.

Required Details:To provide more specific information, please provide the following:

  • 1. Required capacity (tons)
  • 2. Lifting height (meters)
  • 3. Power supply (voltage, phase, frequency)
