What Our Customers Say
Purchased for Canadian Tire 108. The jacks, the pricing, and the service are all excellent. If you're considering buying, go right ahead, you won't be disappointed
The SELR20 Electric Pallet Jack is not only a top-quality product but also backed by customer service that sets Sumachay apart from the competition. A true differentiator in the market.
Sumachay Lifts saved the day during a critical project. We urgently needed stretch wrap, and their next-day shipping allowed us to stay on schedule. Their supply chain expertise and customer service are second to none
SST15+ Sumachay Plus Series
The SST15+ is what we recommend for warehouses running daily or multi-shift. It has the AC drive, proportional lift and lowering, fault code diagnostics, and an 18-month warranty. If you need a stacker that shows up every day and doesn’t create problems, this is the one.
Precision Control
Proportional lift and travel — your operators place loads exactly where they need to go
Controlled Lowering
Lowering buffer keeps pallets and product from getting jarred on the way down
Fault Code Diagnostics
When something’s off, the display tells you what it is — no guessing, no waiting for a tech
Protected Components
Wiring and internals are covered, so forklifts and tight aisles don’t chew them up
Choosing between SST15 and SST15+?
If you run daily, multi-shift, or care about uptime — choose SST15+.

Warehouse Racking & Aisle Planning Guidance
When designing racking or planning warehouse layouts around the Sumachay SST15+, the following clearance details should be considered.
In practice, we recommend planning for at least 91–92″ of clear aisle width to allow for safe and comfortable operation.
- Right-angle stacking aisle (48″ load) ~90.16″
- Recommended planning width 91–92″
- Straddle-leg width (each, widest) ~3.55″
| Position | Inner Width | Outer Width |
|---|---|---|
| Narrow | 38.2″ | 45.3″ |
| Middle | 43.7″ | 50.8″ |
| Wide | 49.2″ | 56.3″ |
For standard 40″ × 48″ skids, we generally recommend the middle position, which provides a 43.7″ inner width. The wide position can be used if additional clearance is preferred.
Total Cost of Ownership
Dealer-sold 1.5T AC straddle stackers typically run $9,500–$11,000 in Canada. The SST15+ matches the core specs at $2,500–$4,000 less.
- Factory direct pricing: vs. $9,500–$11,000 from traditional dealers
- 18-month warranty eliminates early-life repair costs (typically $300–$800 per incident)
- Diagnostic fault codes reduce technician callouts — one avoided call covers the difference
- Lithium-ion battery: zero watering, zero acid checks, zero replacement cost during warranty
Based on published dealer pricing for comparable 1.5T AC-motor straddle stackers in Canada (2025–2026).
Extended Warranty — Standard on SST15+
Every SST15+ ships with an 18-month warranty — 50% longer than the standard SST15. That extra six months covers the period when most early-life issues surface, so you’re not paying out of pocket for them.
Diagnostics & Service Readiness
When something goes wrong with a stacker, the expensive part is usually figuring out what it is. The SST15+ shows you a fault code on the display so your team can diagnose the issue before calling anyone.
Clear Fault Codes
The controller display shows alphanumeric codes — look it up in the manual, know what’s wrong
Skip the Guesswork
Your maintenance person can identify the problem and order the right part the same day
Less Downtime
Diagnose, order, replace — no waiting days for a technician to come look at it
Accessible Service Points
Components are laid out so your team can actually get to them without disassembling half the machine
E21
Motor controller communication error — check wiring harness connection
Here’s the math: A service call starts at $150+ just for diagnosis. If your team can read the code and identify the problem themselves, you skip that cost entirely — and get the right part ordered the same day instead of waiting for a technician visit.
