4000kg Telescopic Forklift with Outriggers: The Physics of High-Altitude Stability
Hoisting a 4-ton industrial payload at major infrastructure sites or mining yards is a strict test of mechanical physics and resistance to gravitational moments. When a four-section boom extends to its absolute physical limits, the massive forward shift in the load's center of gravity turns standard pneumatic tires into a tipping hazard. To physically lock the chassis to the ground, the 4000kg Telescopic Forklift with Outriggers utilizes heavy-duty hydraulic stabilizer legs. By extending the fulcrum point forward and laterally, it transforms a wheeled chassis into an immovable lifting platform, structurally eliminating the risk of forward rollovers during maximum-capacity lifts.
Cummins Torque Reserve and Carraro Drivetrain Integration
Moving a fully loaded chassis across unpaved ground, deep mud, or construction debris requires unyielding low-RPM mechanical torque. This heavy-duty machine is powered by the Cummins Euro III QSB3.9-C110 diesel engine, delivering a continuous 81 KW of net power with minimal thermal degradation during extended shifts.
To ensure this power translates directly into physical ground traction, our engineering team integrated an authentic Carraro high-low speed electronically controlled gearbox and a Carraro heavy-duty wet brake axle. Combined with an impressive 0.43-meter ground clearance and aggressive 440/80R24 off-road tires, the undercarriage crushes through site obstacles. Furthermore, three independent steering modes-front-wheel, four-wheel, and crab movement-allow this massive machine to navigate tightly spaced scaffolding with a minimal external turning radius of just 4.2 meters.

Liebherr Hydraulic Architecture and ±9° Frame Tilting
Executing a material placement at an extreme height of 17.6 meters demands flawless fluid control. Any minor hydraulic leakage or stutter from cheap gear pumps translates into violent mast swaying. To guarantee millimeter-level precision, this chassis is equipped with a closed hydrostatic system driven by a Liebherr piston pump and a Liebherr variable pump/motor.
Governed by a load-sensitive multi-way valve electro-hydraulic control system, the operator maintains absolute micro-movement authority over the boom. More importantly, this chassis integrates a hydraulic frame tilting function. Even when deploying the outriggers on gradients or uneven mud, the operator can adjust the entire frame within a ±9° tolerance to achieve absolute horizontal leveling. This ensures the mast's vertical axis remains perfectly perpendicular to gravity, permanently eliminating lateral metal fatigue and side-tipping risks.
Eliminating Retail Margins with Direct China Suppliers
For large-scale contractors and equipment rental fleets, controlling the Total Cost of Ownership (TCO) is the core metric for profitability. Sourcing specialized heavy machinery through multi-tiered overseas dealer networks introduces heavy retail markups that severely damage your capital ROI.
By bypassing the intermediaries and dealing directly with a heavy machinery factory, you secure your industrial assets at authentic B2B pricing. As direct China suppliers, we ensure your 4000kg Telescopic Forklift with Outriggers rolls off the assembly line equipped with premium industrial components-including an integrated torque limiting system, a ROPS/FOPS luxury air-conditioned cabin, a 10-inch color LCD monitor, and imported Michelin rubber hoses enclosed in protective sheaths.
