Model format: ZWW-L [capacity_kg]/[lift_mm]. Standard rack length shown; different lengths available on request. Compressive (pushing) load possible up to 1,200 kg on request. ZWW-L 1200/1400 specifications estimated, contact us to confirm.

Key Features

  • Wall-mounted design: Bolted to a wall, structural frame, or rigid mounting point for fixed-position lifting and pulling.
  • Compact, lightweight: Light-duty jacks 5.4 to 13 kg, easily portable for installation.
  • Worm and spur gear drive: Smooth manual operation.
  • Tensile or pressure operation: Lift, lower, pull, or push. Pressure mode available on request.
  • Solid steel rack with load fixing hole: Direct yoke, eye bolt, or shackle attachment.
  • Folding handle crank option: Compact storage for tight installations.
  • Multi-jack coupling: 3/4 inch or 1 inch tube (DIN 2440) couplings for synchronised systems up to 1,000 kg total.
  • Explosion-proof variant: 600 and 1,000 kg available in ATEX-rated design on request.

Suitable Applications

Universal light-duty wall-mounted jack. Applications: machinery installation and adjustment, fixed-position lifting in maintenance bays, agricultural and forestry workshops, industrial process equipment, building services, fabrication fixtures, ZWW-L coupled levelling systems, sluice gate auxiliary drives.

How to Use the Pfaff-Silberblau ZWW-L Wall-Mounted Rack & Pinion Jack (Light Duty)

  1. Select model: Match capacity (300/600/1200 kg) and lift travel to your application.
  2. Mount the jack: Bolt to a rigid wall or structure rated for WLL plus safety factor.
  3. Connect to load: Use rack bore hole to fasten yoke, eye bolt, or shackle.
  4. Fit crank: Folding handle or standard crank matched to gearbox. See Pfaff Cranks product.
  5. Verify free movement: Manually check rack moves through full travel.
  6. Operate: Steady crank rotation. Hand effort: 10 daN (300 kg), 14 daN (1200 kg), 15 daN (600 kg).

Warning: Wall mounting structure must be rated for jack WLL plus appropriate safety factor.

Safety Information

  • Always inspect the jack before each use (base plate, rack, gear housing, crank).
  • Never exceed the Working Load Limit stamped on the jack body.
  • Use only the manufacturer-approved crank, never with extension bars or mechanical drives.
  • Never use on soft ground, ice, or unstable surfaces.
  • Never side-load, angle-load, or use the jack to lift persons.
  • For sustained load support, place additional supports beside the jack before any work beneath the load.
  • LOLER 1998 thorough examination required every 12 months where used as lifting equipment.
  • Wall mounting must be rated for WLL plus safety factor.
  • For pressure operation, special-order, contact us to verify compatibility.
  • Multi-jack coupled systems require synchronisation.

Inspection and Maintenance

Lubricate worm and spur gears annually under normal use. Inspect rack, gearbox, mounting plate bolts, and crank at each LOLER examination. Load brake is sealed. WOLFF Onsite provides LOLER inspection.

Optional Accessories

  • Pfaff Cranks: Folding handle and standard cranks for ZWW-L operation.
  • Pfaff Worm Gear Drive S20: Bolt-on for reduced hand effort, self-locking.
  • Custom rack length: Different rack lengths than standard available on request.
  • Multi-jack coupling: Tube couplings for synchronised systems.
  • Explosion-proof variant: 600 and 1,000 kg ATEX-rated on request.

Frequently Asked Questions

Q: What does ZWW-L [cap]/[lift] mean?

First number is capacity in kg (300/600/1200); second is lift travel in mm (400/600/800/1000/1200/1400).

Q: Pressure operation?

Standard ZWW-L is tensile. Pressure (pushing) operation up to 1,200 kg available on request.

Q: Multi-jack coupling?

Yes, ZWW-L jacks couple via 3/4 inch or 1 inch tubes (DIN 2440) for synchronised multi-jack systems up to 1,000 kg total. Three configurations: in line, at 90ยฐ, or across a surface area.

Q: ATEX version?

600 and 1,000 kg ZWW-L variants available in explosion-proof design on request.

Q: Worm Gear Drive S20 compatible?

Yes, S20 (25 mm shaft) is specifically designed for the ZWW-L range, providing 20:1 reduction with self-locking action.

Q: Why does the lift per crank rotation differ between 300/600 kg and 1200 kg models?

The 300 and 600 kg ZWW-L use an 11 mm per rotation gear ratio for fast lifting at lower loads. The 1,200 kg variant uses 3.6 mm per rotation for low-effort lifting at higher loads. Lighter loads lift fast (11 mm, 10 daN); heavier loads lift slowly (3.6 mm, 14 daN). Total system effort per unit lift is similar across the range.

Q: Why is there no Compass datasheet for the ZWW-L?

The ZWW-L range was not bundled with a dedicated datasheet PDF in the Compass dealer portal at the time of capture. The specifications are published in the full Pfaff-Silberblau Hoisting catalogue (Chapter on Rack & Pinion Jacks, pages 126 to 128). Contact us for catalogue extracts or a consolidated technical data sheet.
