| Tandem Set | Combined Payload | Per-Unit Payload | Typical Use | Drive Per Unit |
|---|---|---|---|---|
| STC-15+15 | 30 ton | 15 + 15 ton | Long parts (girders, pipes, large structurals) | 1000W BLDC + L-series gearbox |
| STC-25+25 | 50 ton | 25 + 25 ton | Mold sets, machine bases, transformer cores | 1000W BLDC servo + planetary |
| STC-50+50 | 100 ton | 50 + 50 ton | Ship hull blocks, large transformer, heavy machinery | 2000W BLDC servo + planetary |
AGV Tugger — Synchronized Tugger AGV Pair For 50+ Ton Loads.
Also known as: tugger AGV, AGV electric tugger, AGV tractor, AGV tow tractor, tugger AGVs, AGV tugger train, electric tug. Built for AGV pulling, AGV towing, AGV tugging applications where a single carrier cannot handle the load alone — ship blocks, transformer cores, long structural parts, multi-piece mold sets.
When the load goes past 50 ton — a ship hull block, a transformer core, a complete machinery base, a multi-piece mold set — no single carrier can take it on one turret. The standard answer is two carriers operating in front+rear tandem, electronically synchronized so they move as one unit. This is what AGV tractor / AGV pulling / electric tug means in heavy industry.
Pair Configuration
Three Standard Tandem Configurations
Combined payload doubles when both units share the load.
Where Tandem AGV Pulling Wins
01
Shipyard block transfer
Ship hull blocks 50–100 ton from fabrication shed to dry dock. Outdoor IP build. Standard tandem-pair scenario.
02
Transformer / generator core
50–80 ton transformer cores moved between coil winding shop and final test. Pair handles weight + length together.
03
Long structural parts
20+ m girders, large pipes, structural members. Two units front+rear at the lift points avoid cantilever stress.
04
Multi-piece mold set transfer
Stamping mold sets where the assembled set exceeds 50 ton — common in automotive and appliance plants.
05
Heavy machinery final assembly
Complete machine bases moving between assembly station and test station. Tandem pair lifts on two turrets, no crane needed.
AGV Tractor / Tugger / Electric Tug — What's What
Across English procurement language, several terms describe similar functions. Use whichever term your team uses; we map it to the right spec on our side.
- AGV tractor — most often paired carriers for 30–100 ton single loads
- AGV tugger / tugger AGV — usually a small lead unit pulling a train of carts (lighter loads, lighter platform)
- AGV electric tug — pendant-operated small unit, usually below 5 ton, for pull-through workshops
- AGV pulling / AGV towing — same family, depends on whether the load is on a hitch or a platform
- AGV tow tractor — same family, a synonym for tugger AGV in some markets
Tell Us The Single-Load Tonnage And Length.
For tandem-pair recommendation we need: total single-load weight, load length, lift point distance, floor type (indoor / outdoor), navigation preference.
