When it comes to safely and efficiently connecting your trailer to your tow vehicle, a reliable trailer jack isn’t just a convenience—it’s a necessity. At Hitches and Couplers, we’ve spent years helping customers find the right lifting solutions for everything from small utility trailers to heavy-duty equipment haulers. While there are many jack designs on the market, electric hydraulic trailer jacks have become the gold standard for those seeking power, speed, and minimal effort.

In this guide, we’ll give you a complete overview of the main trailer jack types, then dive deep into why electric hydraulic jacks are the go-to choice for demanding applications.

The Main Types of Trailer Jacks

Although they all serve the same core purpose—raising and lowering the trailer tongue or frame—different jack designs suit different needs.

1. Manual (Crank) Jacks

These are the most common and affordable type. A hand crank turns a threaded rod, which raises or lowers the trailer’s leg. They’re simple, low-maintenance, and reliable. However, they require physical effort and can be slow when lifting heavy loads.

Best for: Light- to medium-duty trailers, occasional use.

2. Electric Screw Jacks

Instead of a hand crank, an electric motor spins the threaded rod. This reduces physical strain but still relies on mechanical screw motion, which can wear over time under heavy loads.

Best for: Medium-duty trailers where convenience is a priority.

3. Hydraulic Jacks (Manual Pump)

These use hydraulic pressure to lift, usually via a hand pump. Hydraulics provide smoother and stronger lifting than screw jacks, but you still have to operate the pump manually.

Best for: Heavy trailers in settings without access to trailer battery power.

4. Electric Hydraulic Trailer Jacks

This design combines the smooth, powerful lifting of hydraulics with the push-button convenience of electric operation. A 12V electric motor powers a small hydraulic pump, which pressurizes fluid inside a cylinder. The result is quick, quiet, and effortless lifting, even with extremely heavy loads.

Best for: Heavy-duty trailers, frequent hitching/unhitching, and users who value speed, safety, and convenience.

How an Electric Hydraulic Trailer Jack Works

Electric hydraulic jacks may look similar to other jacks from the outside, but the magic is in their internal design:

1. Power Source – Connected to your trailer or RV’s 12-volt battery.
2. Electric Motor – Activates when you press the switch, powering the hydraulic pump.
3. Hydraulic Pump – Pressurizes hydraulic fluid, usually oil.
4. Hydraulic Cylinder – Uses that pressure to extend a piston, raising the trailer.
5. Control Valves – Direct fluid flow for lifting, holding, or lowering.
6. Safety Features – Overload protection and manual backup options.

Because hydraulic fluid is nearly incompressible, this system multiplies the motor’s power, allowing it to lift far more than a screw jack of similar size.

Key Benefits of Electric Hydraulic Trailer Jacks

While each type of jack has its strengths, electric hydraulic systems stand out for several reasons:

1. Minimal Effort

With manual jacks, the heavier the trailer, the harder you work. An electric hydraulic jack eliminates the strain. The push of a button does all the work—ideal for those who hitch and unhitch frequently.

2. Superior Lifting Power

Hydraulic pressure delivers tremendous force. Heavy RVs, boat trailers, and loaded equipment haulers can be lifted without overloading the jack or straining components.

3. Smooth, Controlled Motion

Unlike screw jacks, which can bind or jerk under heavy loads, hydraulics operate smoothly and quietly. This makes positioning easier and safer.

4. Faster Operation

Many electric hydraulic jacks can fully raise or lower in a fraction of the time it takes a manual crank. That’s more time on the road—or on the water—and less time fussing with equipment.

5. Durability Under Load

Hydraulic systems handle high weight capacities day after day with less wear on moving parts. With proper maintenance, they deliver years of reliable performance.

6. Safety Features

Quality electric hydraulic jacks include built-in overload protection, preventing accidental damage from lifting beyond rated capacity. Many also feature manual overrides in case of electrical failure.

Applications: Where Electric Hydraulic Jacks Shine

Electric hydraulic trailer jacks aren’t just for large RVs—they’re the smart choice anywhere heavy lifting and frequent use are involved.

Heavy Boat Trailers

Launching and retrieving boats often involves steep ramps and varying loads. Hydraulic jacks provide the strength and precision to keep your trailer level and secure.

Large Travel Trailers & Fifth Wheels

These rigs put serious weight on the tongue or kingpin. An electric hydraulic jack handles the load without wearing you out, making setup and breakdown faster.

Equipment & Utility Trailers

From skid steers to construction materials, equipment trailers often carry shifting or uneven loads. Hydraulic lifting ensures stable, controlled height adjustments.

Commercial Fleets

For businesses that hitch and unhitch multiple times a day, the time savings and reduced labor add up quickly.
