This new configuration features a customized 3-stage mast with 3600mm lifting height and is powered by the reliable American Cummins L9 series engine, delivering stronger performance and improved working flexibility for heavy-duty material handling environments.For industries handling long and oversized materials such as steel profiles, pipes, timber, and precast components, this 20T side loader provides both structural strength and operational precision.
Customized 3-Stage Mast- Lower Height, Greater Flexibility

The standard configuration of the FLIFT 20T side loader forklift comes with:

 2-stage mast

3500mm lifting height
Mast lowered height: 3690m
Overall dimension: 3780mm × 3570mm × 3690mm,
However, many heavy industry clients require better clearance performance, especially when operating inside workshops or loading containers.
To meet this demand, FLIFT engineered a strengthened 3-stage mast with 3600mm lifting height.

3-Stage Mast Configuration:

Lifting height: 3600mm
Mast lowered height: 3100mm
Overall dimension: 3780mm × 3570mm × 3100m
Compared with the 2-stage mast, the 3-stage mast reduces the collapsed height by nearly 600mm, significantly improving access to low-clearance buildings and transport containers.
