Ultimate Guide: How To Choose The Best Caravan Jack

Let's face it, when you're out exploring the stunning landscapes of Australia, the last thing you want is to be stuck with a flat tyre or struggling to level your caravan with a dodgy jack. Choosing the right caravan jack isn’t just a matter of convenience; it’s about safety. A jack that fails under the weight of your caravan can lead to serious accidents and damage. Here at My Generator we've got a range of options, from simple mechanical jacks to powerful hydraulic caravan jacks and convenient electric caravan jacks. Whether you’re changing a tyre, levelling your rig, or performing routine maintenance, the ability to safely lift and support your caravan is crucial. And that all starts with understanding the importance of matching the jack's weight capacity to your caravan. Let’s dive in and find the best caravan jack for your travels.

 

Understanding Caravan Weight Specifications

Let's talk about something that's absolutely vital for choosing the right caravan jack: understanding your caravan's weight. It's not just about guessing; it's about knowing the numbers to stay safe and compliant.

 

Tare Mass: The Starting Point

First up, we have the tare mass. This is essentially the weight of your caravan as it rolls off the factory floor, without any of your personal belongings, water, or gas. Think of it as the empty weight. 

 

Gross Trailer Mass (GTM): The Critical Figure

Then there's the Gross Trailer Mass (GTM). This is the maximum permissible weight of your fully loaded caravan when it's supported by its own wheels. This is the figure you absolutely need to pay attention to when selecting a caravan jack. Why? Because exceeding the GTM is not only dangerous but also illegal.

 

Tow Ball Weight: Balancing the Load

Don't forget the tow ball weight. This is the downward force exerted by the caravan’s coupling on your vehicle's tow ball. Getting this right is crucial for stability and handling. Too little or too much tow ball weight can cause serious problems on the road. It also plays a role in how you distribute the weight, and therefore, what jack you might need.  

 

How These Measurements Affect Jack Selection

Here's the key: your caravan jack must be rated to handle at least the GTM of your caravan. If you're using a jack that's under-rated, you're putting yourself and others at serious risk. Imagine trying to lift a caravan that's heavier than your jack's maximum capacity – that's a recipe for disaster. When looking at hydraulic caravan jacks or electric caravan jacks, always double check their maximum lifting capacity.

One of the biggest mistakes people make is underestimating the weight of their loaded caravan. We tend to forget about all the extra gear we pack – water tanks, food, camping equipment, and personal belongings. All of this adds up quickly. Another common mistake is relying on outdated or inaccurate information. Always refer to your caravan’s compliance plate and weigh your caravan when fully loaded if possible, to obtain accurate weights.

 

Types of Caravan Jacks

Let's break down the different types of caravan jacks you'll come across in Australia. Each type has its own strengths and weaknesses, and understanding these differences will help you choose the right jack for your needs.

 

Hydraulic Jacks: Power and Stability

• Operating Principles and Mechanics: These jacks use hydraulic fluid to lift heavy loads. You pump a lever, which pressurises the fluid, pushing a piston up to lift your caravan.

• Weight Capacity Advantages: Typically, these jacks can handle heavier loads, often up to 1600kg. This makes them ideal for larger caravans.

• Best Applications: Perfect for heavy caravans and situations where you need to lift on uneven terrain.

• Popular Brands: Trail-A-Mate and Kojack are well-regarded brands in Australia.

• Pros and Cons:

  • Pros: High lifting capacity, stable, relatively easy to use.

  • Cons: Can be heavier and bulkier than other types.

Australian Safety Standards

When it comes to choosing a caravan jack in Australia, safety is paramount. That's where the Australian/New Zealand Standard AS/NZS 2693:2007 comes into play. It's a key guideline that helps ensure the safety and reliability of vehicle jacks. Let’s break down what you need to know.

 

Certification Requirements: Meeting the Standards

AS/NZS 2693:2007 sets out specific requirements for the design, construction, and testing of vehicle jacks, including those used for caravans. Manufacturers who comply with this standard demonstrate that their jacks have undergone rigorous testing and meet the necessary safety criteria. This includes tests for lifting capacity, stability, and durability.

 

How to Verify Compliance: Look for the Mark

When purchasing a caravan jack, look for the compliance mark or certification that indicates it meets AS/NZS 2693:2007. This mark is your assurance that the jack has been tested and meets the required safety standards. Reputable brands will clearly state their compliance with this standard. If you're unsure, ask the retailer or contact the manufacturer directly.

 

Safety Rating Terminology

The standard also defines safety rating terminology, which is crucial for understanding a jack's capabilities. You'll often see terms like "maximum lifting capacity" and "rated load." These terms indicate the maximum weight the jack can safely lift. Always ensure the jack's rating exceeds your caravan's GTM (Gross Trailer Mass) to provide an adequate safety margin.

 

Installation and Maintenance 

Getting your caravan jack installed correctly and maintaining it properly is crucial for safety and longevity. Let’s walk through the steps and tips you need to know.

 

First-Time Setup Instructions: Getting Started Right

Read the Manual: Always start by thoroughly reading the manufacturer's manual. It contains specific instructions for your jack model.

Gather Your Tools: Ensure you have the necessary tools before you begin. Some of the tools needed include wrenches, a socket set, torque wrench, measuring tape, level.

 

Step-by-Step Mounting Procedures:

1. Locate Mounting Points: Identify the recommended mounting points on your caravan chassis. These are usually reinforced areas.

2. Position the Jack: Position the jack according to the manual’s instructions. Ensure it’s level and secure.

3. Bolt the Jack: Use the appropriate bolts and washers to secure the jack to the chassis. Tighten the bolts to the manufacturer’s specifications.

4. Check Alignment: Ensure the jack is properly aligned and won’t interfere with other components.
