HAHA vending trays & pull-out shelves

A pull-out tray kit for each HAHA Vending smart cooler, built around that cooler's original trays. Operators call them drawers: each tray slides out for loading and locks closed for customers. Pick your machine; every kit covers all six of its shelves. CE shelves, the version customers pull out themselves, are coming soon. New to it? Read how HAHA trays and shelves work.

Start with your cooler

Pick your cooler. Every kit uses your machine's original trays, so there's nothing to measure.

Every kit covers the whole machine.

Every kit covers all 6 shelves of your HAHA, all OE-L: your key opens one locking shelf at a time, and customers never touch a tray. CE shelves, the version customers pull out themselves, are coming soon. When they ship, you’ll swap them into any kit for $15 each.

HAHA vending tray kit questions

Do I need to replace my shelves?

No. Smart Shelves is a revision kit that clips onto the trays already in your HAHA, with no screws. The pushers, dividers and price tags stay where they are.

Which kit do I order?

Order the kit named after your cooler: Mini 360, Plus 440 or Pro 542. Every kit covers all six shelves of that machine, all OE-L. CE shelves are coming soon; join the waitlist on the kit page and we’ll email you when you can swap them in.

Can a customer pull the tray out?

Not on the OE-L. The tray is locked closed and only your key opens it. The CE shelf, coming soon, is the customer-facing version: the customer pulls it toward them and it glides back on its own.

Can the cooler tip over while I load?

The slide stops well short of the tipping point, and the key fail-safe means only one shelf can be open at a time. That is the whole reason it exists.

Does it block the AI cameras?

No. Travel is set so an open tray stays clear of the cameras that watch the shelves below it.

How long does install take?

About 5 minutes per shelf. Each slide clips onto the tray and into the cooler with no screws, and the printed guide and the video walk you through it. A whole machine takes one short visit.

How many keys come with it?

Two keys with every kit. Keep one on the route and a spare at the shop.

Is it safe?

Every part is designed for the HAHA tray. Only one shelf can be unlocked at a time, travel stops short of the tipping point and clear of the cameras, and safety stickers for the machine come in the box.

What does a kit cost?

$599.95 per machine kit (six shelves, all OE-L), plus flat $19.99 shipping per order to the lower 48. When CE shelves ship, each one you swap in will add $15: $614.95 with one, $629.95 with two, and $689.95 for an all-CE kit as a special order. Installation is not included; the kit clips in with no screws or zip ties.

How does it ship?

By parcel, with tracking, for a flat $19.99 per order to the lower 48. Orders have outpaced our last production run, so kits are on a short backorder: estimated delivery is 7–14 business days, and that includes large and custom orders. Delivery times are always an estimate, not a guarantee.

Can I order a large or custom quantity?

Yes. Large and custom orders have the same estimated delivery of 7–14 business days during the current backorder. For a whole fleet or a mixed set of models, send the details on the contact page and we will quote it.

Is there a fee for paying by card?

No. There are no processing fees: card, Apple Pay, Google Pay, Affirm, Klarna and bank transfer (ACH) all pay the same price. Affirm and Klarna split the purchase into monthly payments, subject to approval.

What if the kit doesn’t work out?

Return it within 30 days of delivery. You cover the return shipping and we refund the kit price once it arrives. Kits are sold without a warranty beyond that.

Do you make kits for other brands?

Qingo, XMAI, TCN, Vendera, SandStar and Micromart kits are on the roadmap. Tell us what you run on the contact page and we will prioritize by demand.
