Application Scenarios
Factory material flow・Building material handling (heavy)・Machinery & equipment handling・Heavy pallet loading
Standard Heavy Pallet Handling (3.0–4.0t)
Moving heavy block bricks, stone slabs, steel coils, or dense raw materials.
Tight Yard & Indoor/Outdoor Transit
Working in yards with narrow aisles where a 5-ton truck is too wide or has too large a turning circle.
Budget-Conscious Fleet Upgrades
Upgrading from 3.5t models to eliminate frequent overload risks without doubling capital expenditure.

Key Features
The CPCD40 4-ton diesel forklift is right-sized for regular heavy loads: 4,000 kg rated capacity for everyday heavy pallet work, a compact 1,480 mm footprint with a 3,050 mm turning radius that a 5-ton truck cannot match in narrow yards, and fuel-efficient low-RPM torque to keep operating costs in check.
Optimal Maneuverability & Compact Footprint
An optimized wheelbase (~1,950 mm) and steering geometry deliver a tighter turning radius than standard 5-ton forklifts, letting operators navigate crowded staging areas and narrow warehouse doors without sacrificing lift capacity.
Heavy-Duty Drive Axle & Reinforced Mast
A wide-view duplex/triplex mast built from high-tensile structural steel, combined with a heavy-duty planetary drive axle, resists mast twist under offset loads and ensures stable, smooth lifting up to 6 meters.
High Torque at Low RPMs - Fuel Efficiency First
Powered by proven industrial diesel engines (Xinchai / Mitsubishi / Isuzu options), delivering high torque at low RPMs for fast acceleration and ramp climbing while keeping hourly fuel consumption up to 15% lower than larger-displacement trucks.
One Truck Across the Worksite
Warehouse → workshop → loading area: a single 4-ton machine covers heavy loads across appropriate indoor and outdoor industrial areas, subject to ground conditions and application requirements.

Choose 4.5T when loads frequently approach or exceed 4 tons and you need additional rated capacity.
Frequently Asked Questions
What is the 4 ton diesel forklift used for?
+
-
It is commonly used for industrial warehouses, machinery workshops, manufacturing plants, logistics centers and building-material handling where loads are generally within the 4,000 kg rated capacity.
Why Choose 4.0-Ton Over 3.5-Ton or 5.0-Ton?
+
-
vs. 3.5-Ton: Eliminates hydraulic strain and frequent safety trip-outs when moving 3.2t–3.8t loads, extending equipment lifespan by 30%.
vs. 5.0-Ton: Saves approximately 20–25% on initial purchase price and burns up to 2 liters less diesel per operating hour.
Can the 4-ton diesel forklift operate inside standard shipping containers?
+
-
Yes, when equipped with an optional 2-stage or 3-stage Full Free Lift Mast (FFL) and low overhead guard, the overall height drops to under 2,200mm, allowing seamless container stuffing and unloading.
Is a side shifter or fork positioner available for this model?
+
-
Absolutely. We offer factory-installed Cascade or Liandong side shifters, fork positioners, and hinged forks with third/fourth auxiliary hydraulic valve spools pre-wired.
How long is the standard warranty and parts availability?
+
-
All 4-ton forklifts come with a 1-year / 2,000-hour warranty. Spare parts are 100% standardized across global distributors, ensuring quick delivery for routine filters and maintenance components.
