Advance HCL320 Heavy Duty Hydraulic PTO Clutch

Description

The Advance HCL320 Heavy Duty Hydraulic PTO Clutch functions as an active mechanical power-split assembly engineered by Hangzhou Advance Gearbox Group Co., Ltd. specifically to run auxiliary fire pumps, heavy deck winches, independent hydraulic systems, and bow thruster loops without dragging down main propulsion speeds. For shipboard engineers managing multi-tier power grids on commercial tugs, cargo fleets, bulk carriers, and offshore support vessels, a direct drive setup introduces a severe risk of engine stalling or immediate hull pressure drops when high-torque pumps spike under load. This dedicated multi-disc wet system provides a complete physical disconnect, allowing teams to engage massive water monitors or heavy anchoring winches at a moment's notice while the main marine diesel continues to run at an optimal, uninterrupted baseline speed across all commercial ship classes.

Built around a thick-walled 185.0 kg / 407.8 lbs dry weight dampening casing, this power take-off assembly completely isolates high alternating rotational strains from cramped machinery spaces to protect adjacent shaft bearings from micro-fracture damage. Physical alignment relies on an industry-standard SAE 1 or SAE 2 standard housing alignment grid that bolts directly to standard marine flywheels, maintaining an absolute 0° straight in-line transmission plane to eliminate complex offset universal joints or drop-box couplings that cause friction wear. Integrating this rugged, positive-engagement component onto heavy-duty commercial hulls prevents gear-face pitting, controls systemic torsional stress, and allows shipping operations to schedule predictable, low-cost shore maintenance instead of suffering catastrophic mid-voyage mechanical failures.

Key Features of Advance HCL320

• Continuous commercial duty class input power rating of 435 HP / 320 kW drives high-displacement auxiliary pumps without experiencing thermal degradation or frictional slip.
• Structural input torque limit of 2000 Nm / 1475 lb-ft withstands severe resistance spikes and prevents drivetrain shear during sudden winch engagement.
• Operational line pressure of 18.0 to 22.0 bar / 261 to 319 psi ensures instantaneous clamping force and positive multi-disc wet clutch plate alignment.
• Direct 24V DC electronic proportional solenoid valve loop controls modulate clutch engagement speeds to absorb severe torsional shock loading.
• Integrated sea-water cooled shell-and-tube external heat exchanger lowers fluid temperatures rapidly during long-haul commercial towing operations.
• Straight in-line 0° transmission plane axis simplifies engine room layouts by removing complex drop-box alignment mechanisms.
• Universal SAE 1 or SAE 2 standard housing alignment grid bolts directly to matching global marine engine flywheel housings.
• Generous 5.5-liter / 5.8-quarts lubrication oil capacity maintains structural film strength using SAE 30 or SAE 40 heavy-duty marine engine gear oil across all moving internal gear teeth.
• Heavy-duty 185.0 kg / 407.8 lbs dry weight casing dampens destructive low-frequency vibrations generated by medium-speed marine diesels.
• Flexible 1500 RPM to 2100 RPM maximum operational threshold accommodates variable engine speed ranges during tight harbor maneuvering.
