Frequently Asked Questions

What size dump bed is the PH310 designed for?
The PH310 is designed for 8’ to 10’ dump beds when properly matched to trailer design, bed length, load placement, mounting position, overhang, and dump angle.

Does the PH310 include a dump trailer hydraulic pump?
Yes, applicable PH310 kit levels include a KTI 12V DC electric hydraulic pump / hydraulic power unit for dump trailer applications. The pump supports power-up, power-down, and gravity-down operation through the included wired remote on applicable kit levels. The Hoist Only version does not include the pump, remote, hoses, fittings, electrical components, or charging accessories found in the more complete kits.

What is a KTI single / double acting hydraulic pump?
A KTI single / double acting hydraulic pump is a 12V DC electric hydraulic power unit that can support both single-acting and double-acting hydraulic operation depending on the trailer setup. On applicable PH310 kit levels, it supports power-up, power-down, and gravity-down operation. Power-up raises the dump bed with hydraulic pressure, power-down lowers the bed with hydraulic pressure when needed, and gravity-down allows the bed to lower using the weight of the bed, which can help conserve battery power during normal dump trailer use.

What is the difference between the Standard, Deluxe, and Premium kits?
The Standard Kit includes the main hoist, hydraulic pump, hoses, fittings, control components, and safety components. Deluxe adds a 5 amp charger and SP-3 SolarPulse panel. Premium, Premium HD, and Premium HDX add progressively stronger trailer battery charging system packages.

Should I choose the PH310, PH416, or PH516?
The PH310 is rated for 3 tons (6,000 lbs) and is designed for 8’–10’ dump beds when properly applied. For larger 10’–14’ dump bed applications, consider the PH416 6 Ton Hydraulic Scissor Power Hoist Kit or the PH516 8 Ton Hydraulic Scissor Power Hoist Kit.

Can the PH310 be used as a hydraulic scissor lift system for dump trailers?
Yes. The PH310 is a compact hydraulic scissor lift hoist designed to raise compatible dump trailer beds, truck dump beds, and custom dump body builds when properly matched to the application.

How do I choose the right hydraulic scissor hoist?
Hoist selection depends on bed length, overhang, dump angle, load type, mounting position, load placement, and trailer design. For more help comparing models, review our Scissor Hoist Selection Guide or contact Johnson Trailer Parts for fitment support.

Is free shipping included?
Yes, free shipping is available to commercial addresses or local freight terminals in the lower 48 states. Residential and liftgate delivery are available for an additional fee.
