Core Answer

The mast system determines a forklift’s lifting height, operational range, and suitable working environment.
For B2B spare parts procurement, correctly identifying the mast type (Duplex, Triplex, Container, Full Free Lift) prevents mismatches, reduces downtime, and improves operational efficiency.

What is a Mast System?

A mast system is the main lifting structure of a forklift. It includes the mast frame, carriage, chains, rollers, and hydraulic lifting components.
Mast type directly affects maximum lift height, free lift height, and working conditions.

What are the main mast types? 

What is a Duplex Mast?

A Duplex Mast is a standard two-stage mast. It is commonly used in warehouses and indoor operations.
Its advantages are simpler structure, lower cost, and easier maintenance.

Typical use cases:

• Low to mid-height rack operations
• Standard warehouse and workshop environments

What is a Triplex Mast?

A Triplex Mast is a three-stage mast designed for higher lifting heights.
It usually uses a telescopic structure to provide greater lift without increasing the mast’s full height.

Typical use cases:

• High-rise rack storage (usually above 6 meters)
• Dense storage environments

What is a Container Mast?

A Container Mast is designed to work inside shipping containers.
It usually has a longer mast stroke and enhanced stability for confined space operations.

Typical use cases:

• Port container handling
• Logistics centers with container storage

What is Full Free Lift?

Full Free Lift means the forks can lift while the mast itself does not extend upward.
This is a key feature for operations in low ceiling spaces, trucks, or containers.

Benefits:

• Ideal for low-height warehouses
• Reduces risk of mast collision with ceilings
• Improves space utilization

Key Spare Parts & Procurement Tips

• Confirm the mast type: Duplex, Triplex, Container
• Confirm free lift height (especially for Full Free Lift models)
• Confirm load capacity and load center to avoid overloading
• Check common spare parts: mast rollers, chains, hydraulic cylinders, guide rails, seals

What Mast Type Does Hangcha Use?

Hangcha forklifts use different mast types depending on the model and application.
Common mast types used by Hangcha include Duplex (2-stage), Triplex (3-stage), Container mast, and Full Free Lift. The exact mast type is determined by the specific forklift model and configuration.

How to Quickly Identify Your Forklift Mast Type (Fast & Practical)

1. Check the Nameplate / Specification Label

The fastest method is to check the forklift’s nameplate or specification label, usually located near the operator’s cabin or on the chassis.

Look for these fields:

• Mast Type
• Mast Stages
• Lift Height
• Free Lift

If the nameplate lists “Mast Type: Duplex”, then it is a Duplex mast, etc.

2. Identify by Mast Stages (Visual Inspection)

Count the number of mast sections:

• Duplex (2-stage): Two mast sections
• Triplex (3-stage): Three mast sections
• Container Mast: Usually longer mast with special design for container entry
• Full Free Lift: Forks lift without the mast extending

3. Check the Model Code (Common Hangcha Naming Rules)

Some Hangcha models include mast information in the model code.
Typical examples (may vary by region):

• Duplex: often standard without special suffix
• Triplex: may indicate “3-stage” in specs
• Container Mast: may be marked as “Container”
• Full Free Lift: may include “FFL” or “Full Free Lift”

4. Confirm by Lift Height vs Free Lift

If your forklift has Full Free Lift, it will show:

• Free Lift value is close to the maximum lifting height
• The mast does not extend significantly during lifting

This is a clear sign of Full Free Lift configuration.
