Heavy-Duty Pallet Truck with Reinforced Frame and Reliable Hydraulic System

Heavy-Duty Pallet Truck with Reinforced Frame and Reliable Hydraulic System

Engineered for demanding material handling operations, this heavy-duty pallet truck combines a one-piece cast hydraulic unit with a 36-month warranty, a reinforced 900 mm steel stiffener, and a dual‑wheel option for versatile floor conditions. The unit delivers a rated load capacity of 2,500 kg, features a minimum fork height of 85 mm and a maximum lift height of 200 mm, and is available with either an AC pump or a BF pump. The arched fork profile and integrated bearing holes ensure uniform stress distribution, while eight strategically placed grease nipples simplify routine lubrication. With a total fork length of 1,220 mm, an overall width of 685 mm, and a sturdy 90 mm thick stiffener, this model is built for intensive daily use.

Hydraulic Unit and Pump Configuration

The pallet truck is equipped with a choice of AC pump or BF pump, both featuring a one-piece cast housing that eliminates weld seams and potential leak paths. This closed hydraulic system maintains consistent lifting performance under varied loads and operating temperatures. The unit includes an overload protection valve and a controlled lowering mechanism for safe load handling.

The hydraulic cylinder has a piston diameter of 35 mm and a lift stroke of 115 mm, providing smooth and responsive operation. The pump body is manufactured from ductile cast iron, and the entire assembly is sealed with high-grade O-rings and backup rings to prevent fluid seepage. With a 36-month warranty on the hydraulic unit, the design prioritises long-term reliability and serviceability.

Lubrication and Maintenance Points

To facilitate regular maintenance, the truck is fitted with eight grease nipples positioned at all major pivot points, including the linkage joints, axle bearings, and roller assemblies. These lubrication points allow operators to apply grease systematically, reducing friction wear and extending the service life of moving components. The grease nipples are recessed and protected against impact damage, and the recommended lubrication interval is every 50 operating hours or as determined by usage intensity.

Fork Construction and Stress Distribution

The fork arms feature an arched (streamlined) profile that promotes even load distribution across the entire length of the fork. This geometric design minimises localised stress concentrations, reducing the risk of permanent deformation even when handling off-centre loads. The fork tips include an integrated arrow-shaped indicator that provides visual alignment guidance, assisting operators in positioning the truck relative to pallet openings.

Additionally, the fork arms and the rear wheel bearing housing are produced as a single integrated structure, eliminating the need for separate bolted or welded bearing brackets. This一体化 construction enhances dimensional stability and maintains accurate wheel alignment over the truck’s operational life.

Reinforcing Stiffener Specifications

A 900 mm extended stiffener is welded to the underside of the fork frame, increasing bending resistance and torsional rigidity. The stiffener is seated in full contact with the fork surface without gaps, and a segmented welding process is applied to prevent distortion while maximising structural integrity. This reinforcement significantly improves the truck’s ability to withstand shock loads and heavy-duty cycles, contributing to a lower total cost of ownership.

Wheel and Caster Options

The pallet truck is offered with two caster material choices to match different floor surfaces and operating environments. Both options are designed to reduce pushing and pulling forces while ensuring stable load movement.

Performance Characteristics of PU and Nylon Casters

Silent PU wheels incorporate a polyurethane tread bonded to a cast-iron or nylon core, providing excellent floor protection and quiet operation. These wheels absorb minor surface irregularities, reducing vibration transfer to the load and the operator. They are particularly suitable for finished floors where surface appearance and noise levels are critical.

Nylon wheels offer high mechanical strength and low rolling friction, making them ideal for outdoor yards, warehouse aisles with debris, and rough concrete surfaces. Their corrosion-resistant properties ensure reliable performance in humid or chemical-exposed environments. Both caster types are equipped with precision ball bearings and sealed raceways to minimise maintenance requirements.

Load Capacity and Dimensional Summary

Durability and Operational Benefits

The combination of a one-piece hydraulic housing, integrated fork-and-bearing structure, and segmented stiffener welding results in a pallet truck that maintains precise geometry under repeated heavy lifts. The arched fork profile reduces permanent deflection, while the eight grease points enable consistent maintenance without disassembly. These features collectively improve uptime, reduce repair costs, and provide dependable performance in logistics, warehousing, and manufacturing applications.
