Beach Wagon Power Kit

I see quite a few topics on beach wagons but would like to add my question to the mix.  I have an all aluminum beach wagon with dimensions of 29" x 60".  The tires are 18x9.5-8 duro lug tires.  The entire wagon weighs approximately 130lbs.  I have attached a picture of the wagon for your viewing.  I shouldn't be pulling anything over 400lbs when fully loaded down.  I also have a 1" live rear axle.  I am curious on what kit I should go with or should I have a customized kit for this wagon?  I was looking at Kit-145 but am worried it won't have enough power.  I am also concerned about the 10ah batteries it comes with.  I want this cart to stay charged for at lease 1.5 hours of run time.  Please advise.


Thanks in advance,

Chip Elliott

The 750 watt motor has a gear box attached that reduces to 420rpm.  I’ve calculated the sprocket ratio based on my 16” diameter tires.  I have the speed at 3.2mph for the rear axle.

 

1. Do you want the thumb throttle to have a battery level indicator on it? No

2. Do you want the power switch to be on the throttle, or separate from it? On the throttle

3. If you want the power switch to be separate from the throttle then do you want a toggle, rocker, or key switch?

4. What is the Ah rating of the batteries and what type of terminals do they have?  22Ah -  see picture



Awesome, great to see that you have the right motor for the project and have calculated the correct gear ratio.

I created a kit for your project. It is item number KIT-36750-50. Here is the link to it: https://cart.electricscooterparts.com/ProductDetails.asp?ProductCode=KIT-36750-50

We do not have any thumb throttles with switches that do not have battery level indicators, so I had to include a throttle with battery level indicator in the kit. We will wire the throttle so the battery indicator works since it has one. The battery indicator will turn off when the power switch is off so it does not drain the battery when the beach wagon is in storage.

Please have a look at the parts and wire lengths in the kit. If you would like any changes to be made then please let us know.

Please let us know if you have any questions.
I am also looking to build a beach cart from a four wheeler chassis I have tires are 22 inch need to be able to carry approximately 400- 500 lb thinking 36 volt 600 watt geared motor would like to have thumb throttle with reverse not sure of batteries needed thinking 35 amp hour bustle need to know what size sprocket to use it is a live axle just needs to go walking speed
The 36 Volt 600 Watt motor would be a good choice for a 500 pound cart geared for walking speed. Under the most demanding conditions three 35Ah batteries would provide a 1-1/2 hour run time, and under normal conditions even more.

22 inch tires are fairly large as far as carts go so a large axle sprocket would be needed. I ran a gear ratio and sprocket size calculation using the 36 Volt 600 Watt gear motor and here are the results.

A 90 tooth axle sprocket would provide a 3.5 MPH top speed on flat ground. The top speed would be a little slower in the sand so that is why I aimed for 3.5 MPH instead of 3 MPH in the calculation.


The 36 Volt 600 Watt gear motor has a sprocket for #40, #41, and #420 chain and I do not think that off the shelf 90 tooth sprockets are available for these size chains. However a sprocket company called Rebel Gears can custom make it and many of our customers have used them before and have good things to say about them. 


We can put together a kit for your project with the exact parts that you want it to have. If you would like us to start working on a kit then please let us know the parts to base it on such as motor, batteries, throttle, with or without reverse, etc. and then we can start working on the kit for your project.


Here is a list of beach cart kits that we have already put together which you can use for inspiration or you might find one that is perfect for your project as it is. If you find a kit in this list and want something changed on it we can do that so please let us know. https://cart.electricscooterparts.com/SearchResults.asp?search=beach


Please let us know if you have any questions.

Please put together a kit for me 36 volt 600 watt geared motor 3 35amp batteries thumb throttle reverse controller and wiring not sure if anything else also I'll call Rebel for a 90 tooth sprocket what about chain when I talk to Rebel ask for 4:20 chain sprocket?
Also will need charger and wiring diagram because I am not too good with wiring

The 36 Volt 600 Watt motor's sprocket works with #420 chain so the axle sprocket needs to be ordered for #420 chain. We carry #420 chain and can include a length of it and a master link with the kit if you would like?


Would panel mount toggle switches be okay for the power and reverse switches, or do you need for these switches to be on the handlebar?


We could also make the kit with a panel mount key switch for power and the reverse switch either panel mount or on the handlebars?

Toggle switch ok please add in chain and master link
I have got the kit finished. It is our item # KIT-36600G-30. Here is the link to it: https://cart.electricscooterparts.com/ProductDetails.asp?ProductCode=KIT-36600G-30

There is an option on the kit page to select how many feet of #420 chain that you want.

Please have a look at the kit and if there is anything that you would like changed or added to it then please let us know.

Please let us know if you have any questions.

Hello -


I would like to build my own beach cart as well, but I'll need assembly instructions.  Can you help with this?


Also...


I've looked at these two wagons so far:

Would either of the above wagons work?  Do you have a list of specs needed when looking for a wagon....size, clearance, weight, load amount, etc?


Thank you,

Amanda

Hi Amanda,

An electric beach cart needs to have the power from the motor going to both of its rear wheels. If only one rear wheel is powered then it will slip and dig into the sand.

The plastic beach cart in the link above is not a good candidate to convert to electric because it is not made from steel so it can not be welded onto.

The steel yard cart in the link that you posted is a good candidate to convert to electric however doing so would require major modifications such as replacing their fixed rear axle and wheels with a live axle, bearings, bearing hangers, and wheels that attach to the new live axle.

We can supply all of the electrical parts and drivetrain parts up to the axle and we have kits with these parts that are made so all of the parts in the kit are plug and play with each other.

You or a welding shop would need to convert the steel yard cart so it has the right axle and wheels and a place to mount the motor, batteries, and electrical components.


We do not have a list of specifications to follow when looking for a wagon to convert. The wagon should be made from steel and be the right size and have the right weight capacity for your needs though.


Please let us know if you have any questions.

I am building a beach cart as well but I would like to make it RC instead of hand controls on the wagon.  Wagon will be similar size to Chips.  I like the package you made for him.  36 Volt 600 Watt Beach Wagon Power Kit (KIT-36600-02.  Can this be put together with out the hand controls. 

Could you assist with the RC connections?  Will the parts supplied connect to an RC receiver?

Thanks,
Scott

 

Hi Scott,


We have not made a kit before to connect to a remote control so we do not have any experience with making the RC connections and are not sure if the parts in the kit would connect to an RC receiver. 


Our variable controllers are actuated by a negative and +0.8 through 4.2 Volt DC signal. +0.8V being fully stopped and +4.2V being full power. If an RC receiver has or can be programmed to have a variable speed output signal between these Voltage levels then it should work with our controllers. 


Please let us know if you have any questions.
