Take the Heavy Lifting out of your next Crab, Cray or Lobster Pot Haul with this 900W 136kg Heavy Duty Line Hauler

Anybody who has ever tried pulling in a cray or crab pot without using a pulley will know how tiring the process can be. Its tough manual labor, not to mention it can also be dangerous for both the user and the boat. There’s a high risk of hurting yourself physically and scratching up the boat's paint job at the same time. With all that in mind, investing in an electric OzTrap Marine Line Hauler becomes a no-brainer.

This heavy duty 300lb/136kg marine series cray pot line hauler from OzTrap takes the heavy lifting and hauling out of recreational or professional crab, cray and lobster fishing.

It has a line pull capacity of 300lbs, or 136kg, and is designed to minimise the effort required to haul heavy pots, long lines and even anchors. 

Using the supplied base plate, the line hauler is attached to the gunwale of your boat, where it's arm extends out over the edge, allowing the line hauler to lower and lift your pots with the flick of a switch. Thanks to the smart design the unit can quickly and easily be removed from the base plate, and folds flat for easy storage.

The quick mounting system includes an adjustable arm allowing you to quickly set the desired length as required.

Shopping with 4x4 Down Under: I found the team very helpful in the purchasing process and delivery was swift. It would have been good to have a more detailed fitting instructions.
Crab Hauling Made Easy

I have used the OzTrap Pro300 on three occasions since purchase in January 2022. Setting up on the boat took a little work to ensure Line Hauler was securely and appropriately positioned. The short 1.8m power cable dictated the layout. 2.4m would be much better. An electrician was required to make up cable and connections to the battery.
I have found that the line hauler needs to be removed while in transit at sea as the vertical shaft that is inserted into the body of the hauler is quite short and there is excessive movement. This will create problems in the long term. A longer shaft could be worth considering. To prevent corrosion I clean the hauler down with Inox before and after each trip. The Pro300 lifted my spanner tray from a depth of 50m loaded with crabs and a 2.5kg weight in just over one minute. Because it draws up to 160amp I keep the boat motor running while operating the lift. I am very happy with the OzTrap Pro300 and I hope it can handle its work in the long term.

Thank you for your valuable feedback Peter. Your comments regarding the Pro300 have been passed on to OzTrap. If you require anything further please don't hesitate to reach out.

Ozhaul pot hauler

Very satisfied with the product and service. However, did make some minor modifications to suit my needs - removed the pulley system and replaced with ‘horn’. Also removed fixing plate and welded a post for better strength.

Thanks for the review and pic Eric! It's looking great!

Shopping with 4x4 Down Under: Dale was good to deal with and answered my questions promptly. I would recommend anyone to deal with 4x4.

The product was as described and good value for money.

Why Shop at 4x4 Down Under?

We know that you have a lot of options out there, and we’re incredibly grateful that you’re considering spending your hard earned money with us. We like to think we stand out from the crowd in a few ways.

Excellent & Honest Service

We try and provide the best pre and after sales service possible. If you have a question we’re here to help, and if we don’t know the answer we’ll tell you and then do our absolute best to find the answer for you. We’re also here to guide you to the best possible outcome for you. A lot of stores will simply try to up-sell you on the most expensive option. That’s not how we operate. We want to build a relationship with our customers, and the only way to do that is by being honest and direct.

4x4 Down Under is built on honesty and integrity. For example when you make a purchase with us we only charge your account once we confirm the product is ready for dispatch. Although we like to guarantee everything on our store is available we’re not perfect and mistakes do happen. If something turns out to not be available we’ll let you know immediately and you have the option to cancel your order or wait for more stock to arrive. Should you not want to wait the order is voided, and there’s no waiting a week to get your money back (it’s instant!).

Aussie and Proud!

We're Australians, and we like to support our fellow Australians, which is why all our products are sourced locally from the official Australian distributors. Nothing is imported directly and we don't stock any grey imports. This also means that all manufacturer warranties are fully honored by the brands themselves.

No Sales Gimmicks 

When you shop at 4x4 Down Under you don’t have to worry about:
  • Annoying and dishonest ’Sales Timers’ that simply reset every few hours and are there to coerce you into buying.
  • Dishonest “low stock” labels, another coercive sales gimmick.
  • False “John just bought a…” alerts. Our customer alerts (bottom left) are 100% true and we're proud of them.
  • Being bombarded by trust badges and labels everywhere you look that mean nothing. 
  • We don't spam! Your information is safe with us. It will never be shared or sold, or used to fill your inbox with garbage.

Fast Shipping with Insurance!

We've partnered with some of Australia's best couriers and freight agents to ensure your purchase reaches you in super-quick time. Once your order has been dispatched you'll receive tracking information which will allow you to track your order online every step of the way. And if something should happen to your order while in transit you can rest assured that it's insured and you won't lose a dime!

If you still have any doubts feel free to give us a call on 1300 76 86 41, or contact us here. We'd love to hear from you.
