Semi-Electric Straddle Stacker – 3300 lb Capacity Walkie Stacker with 138" Lift Height (Model S33-138S)

Product Description

The MechMaxx S33-138S Semi-Electric Straddle Stacker is a reliable material handling solution designed for warehouses, loading docks, manufacturing facilities, and stockrooms. With a 3300 lb load capacity and a maximum lift height of 138 inches, this stacker allows operators to efficiently lift and stack palletized loads while maintaining stability and safety.

The stacker combines manual propulsion with electric lifting, providing an efficient and cost-effective alternative to fully electric stackers. Powered by a 12V 120Ah maintenance-free AGM battery and a 1.6 kW lift motor, it delivers dependable lifting performance while minimizing maintenance requirements. The built-in 12V/15A charger allows convenient onboard charging for simple battery management.

Designed with adjustable forks and adjustable straddle legs, the S33-138S can handle a variety of pallet widths and load types. Its compact design and 53.2" turning radius make it suitable for navigating narrow warehouse aisles and confined storage areas.

• Ideal for light- to medium-duty warehouse applications

This configuration provides efficient lifting performance while maintaining simple operation.

• Fork width adjustable from 8.3" to 33.5"
• Straddle leg inside width adjustable from 35.4" to 51.2"
• Compatible with multiple pallet configurations
• Improves flexibility for warehouse operations

These adjustments allow the stacker to adapt to various material handling tasks.

The S33-138S is built with a reinforced steel structure designed for durability and stability.

• Double-frame reinforced steel design
• Polyurethane drive and load wheels protect flooring
• Removable load backrest for improved load security
• Stable mast structure for safe lifting

This rugged design ensures reliable performance in demanding work environments.


Enhanced Safety Features

Multiple safety systems help protect both the operator and the load during operation.

These features provide reliable protection during daily material handling tasks.
