Miniload ASRS Steel Telescoping Forks for Tote-Handling Systems & AGVs

Reach, Pick, and Retract

Miniload ASRS telescopic forks are load-handling devices designed to pick, move, and position totes, plastic boxes, and small cartons rather than pallets. Used in automated storage and retrieval systems (ASRS) and on tote-handling AGVs (Automated Guided Vehicles), these extendable forks reach into storage racks to retrieve or deposit containers without repositioning the main machine. Nested telescoping rails provide extended reach from a compact retracted assembly, while fork fingers engage, push, or pull containers during storage and retrieval. Every PBC Linear Steel Telescopic Fork (STF) extends and retracts bidirectionally from the carriage to serve storage locations on either side.

The PBC Linear STF Series is built on the SDP telescoping steel drawer slide platform, combining two SDP rails with a compact aluminum-alloy and formed hardened-steel fork structure and position sensors. Designed for miniload ASRS shuttle vehicles, tote-handling AGVs, lightweight stackers, stacker cranes, and gantry systems, the STF handles standard 600×400mm totes and mixed-size containers from 200–600mm wide. Single Depth forks access the first storage position, Double Depth forks use independent finger sets to service two rows, and Adjustable Depth forks accommodate different container sizes without hardware changes. Motorized configurations feature integrated 400W MOONS AC servo motors, while motorless versions allow customer-supplied actuation.

All STF forks share the following features:

  • Two PBC Linear SDP telescoping steel rails provide guided extension and load support
  • Compact aluminum-alloy and formed hardened-steel construction
  • Bidirectional extension and retraction from either side of the carriage
  • Nested sliding rails provide extended reach with compact retracted dimensions
  • Maximum load capacity: 50kg
  • Maximum no-load speed: Up to 2m/s, depending on configuration
  • Position sensors included for controlled fork travel
  • Single Depth, Double Depth, and Adjustable Depth configurations
  • Integrated 400W MOONS AC servo motor options or customer-supplied actuation
  • Applications: Miniload ASRS, warehouse shuttles, tote-handling AGVs, lightweight stackers and gantry systems
  • Made to order with a standard lead time of approximately 12 weeks

The STF platform allows engineers to select a telescopic fork based on tote dimensions, rack depth, and available mounting space without changing the underlying SDP rail technology. For standalone telescoping steel drawer slides, see SDP.

STF-1D - Single Depth Steel Telescopic Fork

Single depth steel telescopic fork STF-1D

The STF-1D picks and places a single row of 600 × 400 mm standard totes in automated storage and shuttle systems. Two SDP telescoping rails and a formed-steel fork structure extend and retract in both directions from the carriage, so the base unit never has to reposition.

  • Configuration: Single Depth
  • Applicable Case Size: 600 × 400 mm
  • Fork Dimension (L×W×H): 783 × 675 × 242 mm
  • Max Stroke: 910 mm
  • Max No-Load Speed: 2 m/s
  • Max Load Capacity (Fy): 50 kg
  • Max Sag Deflection: ≤ 10 mm at full extension
  • Position Sensors: QTY 3
  • Lead Time: ~12 weeks, standard

STF-2D - Double Depth Steel Telescopic Fork

Double depth steel telescopic fork STF-2D

The STF-2D reaches two rows of 600 × 400 mm standard totes in a single motion, using independent finger sets to service both storage positions across a 1,444 mm stroke.

  • Configuration: Double Depth
  • Applicable Case Size: 600 × 400 mm
  • Fork Dimension (L×W×H): 1,020 × 723 × 233 mm
  • Max Stroke: 1,444 mm
  • Max No-Load Speed: 1.6 m/s
  • Max Load Capacity (Fy): 50 kg
  • Max Sag Deflection: ≤ 16 mm at full extension
  • Position Sensors: QTY 4
  • Lead Time: ~12 weeks, standard

STF-AD - Adjustable Depth Steel Telescopic Fork

Adjustable depth steel telescopic fork STF-AD

The STF-AD services double-row totes from 200 mm to 600 mm wide, letting one fork handle mixed-size storage without a hardware change. Suited to shuttle vehicles and AGVs working mixed-size container storage.

  • Configuration: Adjustable Depth
  • Applicable Case Size: 600 × (200–600) mm
  • Fork Dimension (L×W×H): 1,003 × 1,016 × 233 mm
  • Max Stroke: 1,444 mm
  • Max No-Load Speed: 1.6 m/s
  • Max Load Capacity (Fy): 50 kg
  • Max Sag Deflection: ≤ 18 mm at full extension
  • Position Sensors: QTY 4
  • Lead Time: ~12 weeks, standard
