3T Heavy Duty Lever Hoist 410N Hand Force Manual Chain Pulley Block Tightening Tools
Professional construction lifting and tightening tool designed for lifting, pulling, positioning and tensioning operations in construction, power line installation, and field maintenance work.
Product Overview
The 3T manual lever hoist is a versatile construction tool with 3 ton rated capacity and 410N operating force. Featuring manual ratchet lever operation, it provides stable performance without requiring electricity, making it ideal for outdoor job sites, temporary construction areas, and narrow working spaces.
Common Challenges
Heavy objects that are difficult to lift manually
Limited working space on construction sites
No electric power supply available on site
Unstable pulling force during tightening operation
Low efficiency when adjusting equipment position or chain tension
Root Causes
Insufficient capacity of light-duty lifting tools
Unstable braking system during load holding
Weak chain structure under continuous pulling work
Bulky lifting equipment unsuitable for narrow spaces
Lack of portable manual tools for field operation
Our Solution
3 ton rated capacity for construction lifting and pulling work
410N hand force for controlled manual operation
Ratchet lever structure for lifting, pulling and tightening
High strength chain for stable load bearing
Forged safety hooks for secure connection
Manual operation without electricity

Lifting height and chain length can be customized
Operation Principle
The operator moves the lever handle to drive the internal ratchet gear system. The load chain moves through the hoist body to lift, pull or tighten the load. The braking system helps hold the load in position during operation, allowing workers to adjust the load height, pulling distance or tension more accurately during construction and installation work.
Key Advantages
3 Ton Practical Capacity
The 3T rated load is suitable for common construction lifting, equipment positioning, pulling and tightening work.
410N Controlled Hand Force
The 410N operating force allows workers to control lifting and pulling movement more steadily during field operation.
Manual Operation Without Power Supply
No electricity or hydraulic power unit is required. Suitable for outdoor construction, power line installation and remote job sites.
Compact Chain Pulley Block Design
The compact lever hoist structure is easy to carry, install and operate in narrow spaces.
Suitable for Tightening Tools Application
Can be used for pulling, tensioning and tightening applications in construction, installation and power line work.
Applications
Basic construction lifting
Equipment installation
Steel structure positioning
Power line installation
Cable tightening work
Pole and tower installation support
Machinery maintenance
Workshop lifting and pulling
Field repair operation
Selection Guide
Based on Load Capacity
For light-duty work: 1T or 1.5T lever hoist. For medium-duty construction lifting: 3T lever hoist. For heavy-duty lifting: 6T or larger capacity.
Based on Working Purpose
For lifting work: focus on rated capacity and braking system. For tightening work: focus on operating force and chain strength. For positioning work: choose compact lever hoist type for easier control.
Based on Working Environment
For outdoor construction: choose heavy duty forged hook and strong chain type. For narrow spaces: choose compact manual lever hoist. For areas without electricity: manual ratchet lever hoist is more suitable.
Based on Lifting Height
Standard lifting height can meet most basic construction needs. For special projects, chain length and lifting height can be customized.
