Hoist Capacity vs. Trailer GVWR — What’s the Difference?

A hoist capacity rating is not the same as your trailer’s GVWR or payload rating. Actual lifting performance depends on trailer design, mounting geometry, load distribution, dump angle, and rear overhang.

Always review the official Dexter Power Hoist capacity charts before selecting a hoist for your application.

Choose Your PH630 Kit Configuration

The PH630 is available in four configurations so you can choose the dump trailer lifting system that best matches your trailer build and operational requirements.

← Swipe left/right to compare all kit options →

Hoist Only: Includes the PH630 hoist assembly and mounting brackets for builders supplying their own hydraulic components.

Standard Kit: Complete dump hoist system with KTI pump, hoses, fittings, wiring, remote, hinges, and safety components.

Pro Kit: Standard Kit plus a single Dexter Power Jack hydraulic trailer jack system.

Pro Max Kit: Standard Kit plus dual Dexter Power Jack hydraulic trailer jack systems with a hydraulic flow divider for synchronized operation.

Most buyers choose the Standard Kit for a complete dump trailer setup, while the Pro and Pro Max systems are ideal for trailers requiring powered tongue lifting convenience and integrated hydraulic jack functionality.

Why the Pro & Pro Max Systems Use a Shared Hydraulic Pump

No second pump. No extra wiring.

The Pro and Pro Max kits share one KTI power unit between the dump hoist and hydraulic jacks using a simple selector valve. Fewer components to wire, fewer parts to maintain, and a cleaner setup on the trailer tongue.

The Pro configuration includes a single Dexter Power Jack hydraulic trailer jack system, while the Pro Max configuration includes dual Dexter Power Jacks with a hydraulic flow divider for synchronized lifting performance.

KTI Hydraulic Pump System

Applicable PH630 configurations include a genuine KTI 12V DC hydraulic power unit engineered specifically for dump trailer lifting systems.

The KTI power unit supports power-up, power-down, and gravity-down operation using the included 15’ wired remote control for smooth dump bed operation during loading and unloading cycles.

For trailer builders and repair shops replacing older systems, the PH630 provides a matched setup with compatible hoses, fittings, controls, wiring, and safety components included on applicable kit configurations.

⚡ Protect Your Investment: Why Proper Battery Charging Matters

Dump trailer lifting systems place heavy electrical demand on trailer batteries during raising and lowering cycles. Low voltage conditions can lead to slow lifting speeds, shortened battery life, damaged solenoids, and premature hydraulic motor wear — and it’s one of the most common causes of hydraulic system problems we see in the field.

Johnson Trailer Parts carries a full line of trailer battery charging solutions to help keep your hydraulic system running reliably:

• Road Chargers — Charge your trailer battery directly from the tow vehicle while driving
• SolarPulse® Battery Maintainers — Keep batteries topped off on parked trailers
• Smart Battery Chargers — Great for charging between jobs or during storage
• Battery Optimizer Systems — Combine multiple charging methods for maximum battery protection
