Technical Requirements for AGV Omni‑Directional Transfer Cart

(1) Motion‑control performance: The AGV Automatic transfer cart shall realize forward/backward travelling, side‑shifting and in‑situ rotation to adapt to narrow aisles and multi‑station turning inside workshop. Start‑stop shall be smooth without impact or obvious shaking to guarantee safety of transported goods.

(2) Speed specification: Maximum straight‑line travelling speed ≥48 m/min, multi‑speed adjustable (preset: 0.3 m/s, 0.5 m/s, 0.8 m/s).

(3) Braking performance: At heavy-duty 1000kg-20000kg load and speed of 48 m/min (0.8 m/s), braking distance ≤200 mm. Equipped with laser obstacle‑avoidance (detection distance 500 mm) and bumper‑edge emergency‑stop function.

(4) Slope‑climbing & obstacle‑crossing: Capable of 5° uphill / downhill; no slipping when parking on slope under full‑load condition. Max obstacle‑crossing height ≥10 mm.

(5) Ground adaptability: Tolerate height difference up to 20 mm among four wheels; no jamming or overturning risk during travelling.

(6) Lifting‑mechanism performance

① Transfer cart Lifting stroke ≥130 mm; lifting height with adjustable steps. Both upper and lower limit positions shall adopt mechanical + electrical dual‑limit protection.

② The Electric Transfer Cart at Rated Load Capacity kg load, lifting / lowering speed ≤5 mm/s with smooth action; lifting repeat positioning accuracy ±2 mm. Four lifting units run synchronously to keep platform horizontal.

③ Power‑failure self‑locking: No dropping or slipping under full‑load condition upon power loss.

(7) Auto‑centering function

① Fore‑aft centering: When driving under transfer cart, AGV detects relative fore‑aft position, stops by closed‑loop control at set position and disables forward / backward commands from remote controller.

② Left‑right centering: One‑click auto‑docking mode; automatically measure clearance on both sides and disable steering commands from remote controller.

(1) Top interface & levelling: Integral flat bearing surface with flatness ≤1 mm. Height difference of four corners ≤2 mm before and after lifting to match bottom supporting surface of parked equipment.

(2) Insulation & positioning: Insulation resistance between top supporting surface and vehicle body＞30 MΩ; adopt light‑blue / grey high‑hardness pressure‑resistant rubber. Supplied with removable locating taper pins.

(3) Storage layout: Drawer‑type storage box on vehicle side for taper‑pin storage; hand‑held remote controller can be mounted on battery transfer cart to avoid loss.

(4) Integration & dimension: Charger preferably integrated inside chassis (bonus item for bidding).

Overall dimension L×W×H: 2000 mm×1100 mm×614 mm, top cargo‑carrying width 940 mm. Dimensions shall be confirmed in writing by purchaser, no mechanical interference in operation.(The load-bearing platform of the transport cart can be customized to different dimensions. )

(5) Structural strength: Sufficient rigidity and strength for long‑term operation under rated load; no permanent deformation or abnormal noise.

(1) HMI: On‑board touch panel with touch operation and screen‑lock function. Clear interface for status monitoring, parameter setting and manual operation.

(2) Emergency movement: Mechanical unlock and cable‑controlled movement available under power‑off or fault condition for convenient on‑site handling.

(3) Lifting & forklift pockets: Lifting lugs at four corners plus forklift pockets for transportation of the AGV itself.

(1) Multi‑level obstacle‑avoidance

① Non‑contact laser scanner: Diagonally‑mounted laser sensors; detection range 0.05‑3 m adjustable, response time ≤50 ms. Cover perimeter and height 0‑2000 mm for multi‑stage deceleration and stop.

② Contact safety bumper: Surrounding bumper strips; trigger force ≤50 N, response time ≤20 ms. Power cut‑off and emergency brake once triggered.

(2) Emergency‑stop: Redundant E‑stop buttons both on Self propelled transfer cart body and hand‑held remote controller; dual‑redundant full‑loop design, response time ≤10 ms. Cut‑off whole‑transfer trolley power upon activation.

(3) Audible‑visual alarm: Independent travelling warning (volume adjustable / mute available) and fault alarm with different sound tone.

(1) Fault diagnosis: Built‑in self‑check, alarm and fault‑code output. HMI displays fault information and standardized troubleshooting guidance for fault location.

(2) Emergency evacuation: Allow external tooling for moving when self‑driving fails. Supplier shall provide dedicated evacuation tools and standard operation procedure for safe & quick removal from work area.

(1) Capacity retention (refer to GB/T 31486): ≥80 % capacity after one‑month shelf storage; ≥80 % capacity after 2 000 charge‑discharge cycles.

(2)Industrial Transfer Cart‑level electrical protection: Protection against overload, short‑circuit, under‑voltage, over‑voltage and electric leakage complying with GB/T 20721‑2022; eliminate risk of electric leakage and arcing.

(3) Status monitoring: Real‑time monitoring of battery voltage, current, temperature and SOC; percentage‑of‑charge displayed on on‑board HMI.

(4) BMS internal protection: Full protection against over‑charge, over‑discharge, over‑current, over‑temperature and short‑circuit for safe charge‑discharge and extended service life.

(1) Charger safety: Charging unit integrated with protection for over‑voltage, over‑current, over‑charge, over‑temperature, short‑circuit, reverse connection and electric leakage, complying with national electrical standards.

(2) Communication capability: Reserved interface for future dispatching‑system integration. Support bidirectional wireless communication for uploading charging status, electrical parameters and fault alarms.
