CLARK S40–55 Series: Built Strong for Australia’s Toughest Worksites

The CLARK S40–55 Series continues a legacy more than a century in the making—forklifts engineered to be rugged, reliable, and truly Built to Last. Designed for 4–5.5 tonne applications, these models combine heavy-duty strength with operator-friendly engineering, giving Australian businesses a machine that thrives in demanding environments including logistics yards, steel and timber facilities, construction sites, farming operations, and high-utilisation industrial fleets.

Rugged Construction You Can Rely On

The S40–55 Series is engineered from the ground up for durability. Its solid, fully welded heavy-gauge frame and field-tested nested I-beam mast technology demonstrate the strength Clark forklifts have been known for over generations. These design elements help ensure long operational life, reduce maintenance needs, and support stable handling even under maximum load conditions.

Clark’s commitment to producing forklifts with low operating and maintenance costs is also evident across the S-Series line. The result is a machine ready to face long shifts, rough ground surfaces, and continuous lifting cycles without compromise.

The Unique Clark Mast: Stability, Strength & Visibility

The S40/50/55 Series features a uniquely engineered Clark mast, critical to overall truck durability and stability. This mast design enhances load control, improves lifting efficiency, and contributes to safer operation—particularly important in environments with uneven terrain or heavy-on-heavy handling demands.

In the broader S-Series range, the nested I-beam mast technology further improves rigidity and reduces mast sway, while the lowered crossbar provides operators with enhanced forward visibility.

Built-In Tie-Down Points for Safe, Simple Transport

A standout feature highlighted in the Clark S40/50 Series video is the inclusion of smartly designed, built-in tie-down points, making the forklift easier and safer to secure during transportation between sites. This is especially valuable for Australian operations that move machinery frequently across regional areas, construction projects, and multi-site logistics operations.

These tie-down points help reduce loading time, improve transport safety, and minimise the risk of damage during haulage—supporting efficient, error-free fleet movement.

Optimised Centre of Gravity for Stability Under Load

The S40–55 Series benefits from an optimised centre of gravity, a feature explicitly highlighted as a key strength of the model. A well-balanced centre of gravity enhances the truck’s stability when cornering, lifting, or transporting heavy loads—greatly reducing the risk of tipping and supporting confident handling at full capacity.

Within the broader S-Series lineup, this optimal weight distribution also helps the forklift maintain its rated capacity more effectively and improves overall load stability during high-stacking operations or uneven surface travel.

Engine Options to Suit Every Application

Available in diesel or LPG, the Clark S40–55 gives Australian buyers flexibility to match the truck to their operational environment. These engine choices offer the option of lower emissions with LPG or high-power endurance through diesel—each ideal for different applications and industry needs.

A Strong Choice for Australian Industry

With rugged durability, intelligent design features, enhanced stability, and Clark’s uniquely engineered mast, the S40–55 Series delivers everything Australian businesses expect from a high-performance 4–5 tonne forklift.

Whether you’re operating in harsh outdoor environments, handling heavy industrial materials, or running high-intensity fleet operations, the Clark S40–55 Series provides the strength, stability, and confidence needed to keep your business moving—every shift, every day.
