How to Choose an Electric Hoist

An electric hoist is one of the most important lifting components in industrial crane systems. It directly affects lifting safety, operating efficiency, positioning accuracy, and maintenance costs.

However, choosing the wrong electric hoist can lead to overload risks, frequent failures, excessive downtime, and reduced equipment lifespan.

Therefore, businesses should evaluate load requirements, working conditions, duty classification, lifting speed, and installation space before selecting an electric hoist.

In this guide, Hanko explains how to choose the right electric hoist for industrial applications.

Featured Snippet: How Do You Choose an Electric Hoist?

To choose the right electric hoist, you should evaluate:

• 정격 인양 능력
• Lifting height
• Duty classification (M3–M8)
• Lifting speed
• Power supply requirements
• Working environment
• Installation space
• Safety and maintenance requirements

The correct electric hoist improves operational safety, lifting efficiency, and equipment lifespan.

1. What Is an Electric Hoist?

An electric hoist is a powered lifting device that uses:

• An electric motor
• 기어박스
• 제동 시스템
• Drum or chain wheel
• Wire rope or chain

to lift and lower heavy loads.

Electric hoists are widely installed on:

• 오버헤드 크레인
• 갠트리 크레인
• Jib cranes
• Monorail systems
• Workstation cranes

They are commonly used in factories, warehouses, workshops, ports, steel plants, and construction sites.

2. Main Types of Electric Hoists

Before selecting a hoist, it is important to understand the main types available.

2.1 Wire Rope Electric Hoist

Wire rope hoists use steel wire ropes for lifting operations.

Advantages

• Higher lifting capacity
• Longer lifting height
• Smooth operation
• Suitable for heavy-duty applications

Typical Capacity

0.5 ton to 80 tons or more

Common Applications

• 제조 공장
• Steel mills
• Heavy industry
• Logistics centers

👉 Wire rope hoists are ideal for high-capacity industrial lifting.

2.2 Chain Electric Hoist

Chain hoists use alloy lifting chains instead of wire ropes.

Advantages

• Compact structure
• Lightweight design
• Easier installation
• Better for limited spaces

Typical Capacity

0.5 ton to 60 tons

Common Applications

• Workshops
• Maintenance stations
• Assembly lines
• Small lifting systems

👉 Chain hoists work well in compact industrial environments.

2.3 Explosion-Proof Electric Hoist

Explosion-proof hoists are designed for hazardous environments.

Suitable Industries

• Chemical plants
• Oil & gas
• Mining
• Explosive material handling

These hoists comply with explosion-proof safety standards.

3. Determine the Required Lifting Capacity

The first step in electric hoist selection is calculating the rated load.

What to Include

You should include:

• Load weight
• Packaging weight
• Lifting attachments
• Hook weight

Best Practice

Choose a hoist with a slightly higher rated capacity than the maximum expected load.

For example:

👉 Safety margin helps prevent overload and extends hoist life.

4. Select the Correct Lifting Height

The required lifting height depends on:

• Building height
• Equipment clearance
• Hook travel distance
• Obstacle position

Important Tip

If headroom is limited, choose a:

• Low headroom electric hoist

This design maximizes lifting height in restricted spaces.

5. Understand Hoist Duty Classification

Duty classification determines how intensively the hoist can operate.

Common Duty Classes

Factors Affecting Duty Class

• Working frequency
• Daily operating hours
• Load percentage
• Start-stop cycles

👉 Selecting the wrong duty class significantly shortens hoist lifespan.

6. Choose the Appropriate Lifting Speed

Lifting speed affects productivity and positioning accuracy.

Single-Speed Hoist

Features

• Simple structure
• 더 저렴한
• Standard lifting speed

Typical Speed

8 m/min

Suitable For

General industrial lifting

Dual-Speed Hoist

Features

• Fast lifting + slow positioning
• Improved accuracy
• Safer load handling

Example Speed

8/0.8 m/min

Suitable For

• Precision handling
• Mold lifting
• Equipment installation

Variable Frequency (VFD) Hoist

Advantages

• Smooth acceleration
• Precise speed control
• Reduced impact load
• Energy savings

👉 VFD hoists are increasingly popular in modern automated factories.

7. Confirm Power Supply Requirements

Always verify local power conditions before purchasing an electric hoist.

Common Power Configurations

• 3-phase 380V
• 3-phase 415V
• Single-phase 220V

Why It Matters

Incorrect voltage selection may cause:

• Motor overheating
• Brake failure
• Electrical damage

8. Consider the Working Environment

Operating conditions strongly influence hoist selection.

8.1 High Temperature Environment

Choose:

• Heat-resistant motors
• High-temperature cables
• Special lubrication systems

Common Industries

• Steel plants
• Foundries
• Metallurgical workshops

8.2 Corrosive Environment

Choose:

• Corrosion-resistant coatings
• Stainless steel components
• Sealed electrical systems

Common Industries

• Chemical plants
• Coastal facilities

8.3 Hazardous Environment

Use explosion-proof electric hoists in:

• Oil refineries
• Gas plants
• Mining operations

9. Evaluate Installation Type

Different installations require different hoist configurations.

Common Installation Types

Fixed Electric Hoist

Installed permanently in one location.

Electric Trolley Hoist

Moves horizontally along beam tracks.

Low Headroom Hoist

Designed for limited ceiling height.

👉 Proper installation selection improves workspace efficiency.

10. Safety Features to Consider

Modern electric hoists should include essential safety protections.

Recommended Safety Features

• Overload protection
• Upper/lower limit switches
• Emergency stop
• Thermal motor protection
• Brake monitoring
• Phase protection

These features reduce operational risks and equipment damage.

11. Maintenance and Serviceability

Easy maintenance reduces downtime and operating costs.

Key Maintenance Areas

• Wire rope or chain lubrication
• Brake inspection
• Gearbox oil checks
• Hook inspection
• Motor temperature monitoring

Important Tip

Choose hoists with:

• Easy-access components
• Available spare parts
• Reliable technical support

Common Mistakes When Choosing an Electric Hoist

Avoid these common selection errors:

❌ Choosing only based on price
❌ Ignoring duty classification
❌ Underestimating lifting height
❌ Using non-explosion-proof hoists in hazardous areas
❌ Selecting insufficient lifting capacity
❌ Ignoring future production expansion

👉 Correct selection reduces long-term operational costs.

How do I calculate electric hoist capacity?

You should calculate:

• Load weight
• Hook weight
• Lifting accessories
• Safety margin

Then select a hoist slightly above the maximum load requirement.

What duty class is suitable for industrial cranes?

Most industrial applications use:

• M5 for medium-duty operations
• M6 or above for heavy-duty continuous operation

Why is low headroom important?

Low headroom hoists maximize lifting height in buildings with limited ceiling space.

How often should electric hoists be inspected?
