A large power transformer manufacturer replaced struggling manual handling with a compact fork-type AMR that shuttles 0.8–3 t transformer units through 1.6 m aisles — transfer time cut from 20 to 3 minutes per unit.
Electric Power & Equipment Manufacturing
The client is a large manufacturer of oil-immersed distribution transformers, covering R&D, assembly and finished-goods outbound. The workshop is compact with dense production lines, and transformer units weigh 0.8–3 t each, palletized on wooden pallets. Aisles between stations are only 1.6–2.2 m wide — traditional heavy internal-combustion counterbalance forklifts cannot turn or travel between the lines, while manual hydraulic pallet jacks make moving heavy transformers exhausting and inefficient. The plant urgently needed compact, short-distance handling equipment.
Equipment deployed: Fork-type AMR
A compact body with an extremely small turning radius travels easily through the workshop's 1.6 m aisles, reaching transformer assembly stations directly and completing a seamless line-off → palletizing → staging flow with no second handling.
The mast load is matched to single-pallet transformer weight; forks pick the wooden pallets precisely and lift smoothly without sway, avoiding collisions with porcelain bushings and copper terminals on top of the units — sharply reducing finished-goods damage and scrap.
Fully electric with zero exhaust and low noise, the AMR fits the clean-production standards of power-equipment workshops. Compared with internal-combustion trucks, there are no engine oil or filter consumables, fewer wearing parts and simpler daily maintenance.
+220%
outbound throughput
Transfer time per transformer fell from 20 minutes (pallet jack) to 3 minutes; daily finished-goods outbound capacity rose 220%.
1 operator + 1 truck
instead of 4 handlers
The work of 4 manual handlers is now done by 1 operator with one MightyCargo forklift.
3.2% → <0.3%
precision-part damage
Transformer damage rate dropped from 3.2% to under 0.3%, saving over 10,000 RMB a year in rework and scrap.
−65%
annual maintenance cost
Lithium charging costs about one-fifth of diesel; annual maintenance spend fell 65%.
+80 m²
of new storage
Narrow aisles are now usable for continuous transfer; idle corner areas were converted into a temporary finished-goods storage zone.
“MightyCargo's fork-type AMR precisely solved our narrow-aisle heavy-load handling challenge. The compact body and stable rated load fit transformer transfer across the full production chain — it is the preferred equipment for short-distance heavy handling in compact electric-equipment plants.”
The customer has since ordered 2 more units of the same model for new production line support.
This deployment validates a blueprint that MightyCargo continues to replicate and refine across the industry.
