Custom Hydraulic Power Units for Mobile Equipment: OEM Capability Guide
Custom Hydraulic Power Units for Mobile Equipment: OEM Capability Guide
A hydraulic power unit (HPU), also called a hydraulic power pack, supplies pressurized oil to hydraulic cylinders and motors. For mobile equipment such as dump trailers, scissor hoists, aerial work platforms, and special-purpose vehicles, the HPU must fit inside a compact vehicle envelope and operate reliably under vibration, temperature changes, and intermittent duty cycles.
This guide is written for OEM buyers moving from evaluation to execution. It explains how to assess a custom hydraulic power unit manufacturer, which customization options matter, and what evidence to review before placing an order.
Problem Definition: Why a Standard Hydraulic Power Pack Often Does Not Fit
Mobile HPU selection fails when the specification is copied from a stationary industrial unit. A dump trailer needs a power-up / gravity-down circuit. A scissor hoist may need a double-acting power-up / power-down unit. An aerial work platform may require multiple valve functions for lifting, steering, leveling, outrigger control, and emergency lowering.
Typical mismatches include the wrong motor voltage, a single-acting circuit where a double-acting circuit is required, no load-holding valve, no weather protection, or a reservoir that is too large for the installation envelope.
That is why mobile equipment buyers rely on custom hydraulic power units. An OEM manufacturer can configure the voltage, motor, pump, manifold, valve, reservoir, and control system around the actual machine rather than forcing the machine to accept a fixed catalog unit.
Industry Background: Mobile Equipment Raises the Demand for Configurable HPUs
Market data shows the scale of the hydraulic power unit industry. Third-party research estimates vary, but published figures for the global market in 2024 include USD 13.6 billion from Grand View Research and USD 11.4 billion from Precedence Research. Grand View Research also reports that Asia Pacific accounted for 40.2% of the global revenue share in 2024.
In the United States, electric-powered hydraulic power units accounted for 60.1% of the revenue share in 2024, according to Grand View Research. Mordor Intelligence reports that standard packaged units accounted for 47.8% of the global revenue share in 2024. For the trailer-related segment, the global dump trailer market was estimated at USD 63.51 billion in 2024 by Market Research Future.
For European applications, buyers should also verify compliance with EN ISO 4413:2010, which sets general rules and safety requirements for hydraulic fluid power systems, and with Machinery Directive 2006/42/EC, which governs health and safety requirements for machinery in the EU.

Use Cases: Mobile HPU Configurations Across Equipment Types
Dump trailer hydraulic power unit
A typical dump trailer application uses a single-acting power-up / gravity-down circuit. The APEX-DTHPU is designed for HTC-series telescopic cylinders and other single-acting cylinders used on dump trailers. In a one-year Canadian dump trailer program, Apex Hydraulic supplied 1,200 sets of HTC Series telescopic cylinders and 500 sets of power units. The result was smooth lifting performance, a stable dumping angle, and reduced service downtime under continuous heavy-duty operation.
Scissor hoist hydraulic power unit
Double-acting DC power units are used on scissor hoist kits for power-up and power-down control. The APEX-CDAMHPU family can be configured with 12V or 24V motors, gear pumps, and solenoid valves to operate with scissor hoist cylinders in dump beds and lifting platforms.
Vehicle hydraulic power unit
For refuse trucks, tailgates, and service vehicles, the APEX-CVMAHPU provides 24V/48V operation, 1–6 hydraulic functions, and chassis-mounting options. This type of unit supports auxiliary functions such as lifting, clamping, and vehicle stabilizer control.
Multi-function hydraulic power unit for aerial work platforms
Aerial work platforms often require 2–8 hydraulic functions in one compact unit. The APEX-CMFHPU can support steering, platform leveling, outrigger control, electric lifting, and emergency lowering in a single manifold-based power unit.
Mini hydraulic power unit
Compact applications need a small package with controlled noise. The APEX-CLNCHPU is a low-noise compact hydraulic power unit available for DC or AC power. It is used in lift tables, access lifts, medical equipment, warehouse equipment, and similar stationary or mobile machinery.
