Pfaff-Silberblau SW-W Wall-Mounted Wire Rope Winch (SG Version)

Model SW-W | Capacity 80 kg – 750 kg | Wall-Mounted Manual Winch | Special-Gear (SG) Drive | Five Capacity Grades | Replacement Crank Handle Available | CE & UKCA Marked | Made in Germany

The Pfaff-Silberblau SW-W (SG version) is the standard wall-mounted manual wire rope winch, covering capacities from 80 kg through to 750 kg across five compact models. The SG special-gear configuration tunes gear ratios for consistent crank-handle feel across the capacity range, with lifting speeds optimised for typical fixed-position lifting tasks. Each model ships with pre-fitted galvanised wire rope sized to capacity — 3 mm on the SW-W 80 up to 7 mm on the SW-W 750 — with top-layer rope lengths between 10 m and 30 m.

Key Features

• Five capacity grades: 80 kg, 125 kg, 300 kg, 500 kg, and 750 kg — covers the light to medium-duty range of fixed-position wall-mounted lifting requirements.
• Special-gear (SG) drive: Gear configuration distinct from the Alpha range, with ratios tuned to deliver consistent crank-handle feel and lift speeds optimised for typical fixed-position lifting tasks.
• Rope diameter matched to capacity: 3 mm to 7 mm wire rope, sized to the rated capacity with appropriate safety factors.
• Pre-fitted galvanised wire rope: Each winch ships ready to use with the correct rope diameter, length, and termination — no separate rope assembly required.
• Wall-mounted design: Direct mounting to any structurally adequate wall via four bolt fixings.
• Replacement crank handle available: Article 39401040 supplies a spare or replacement crank handle as an accessory item.
• Top-layer rope length to 30 m: The SW-W 80 offers the longest standard rope in the range; heavier models trade rope length for capacity headroom.
• Robust mechanical construction: Industrial-grade build for steady daily duty in workshops, plant rooms, and on-site installations.

Technical Specifications

Capacity is the 1st-layer rated load. Lift per crank revolution applies at the top rope layer. A replacement crank handle (article 39401040) is available separately for service or as a spare. Lift speeds range from 170 mm/crank revolution on the light SW-W 80 down to 35 mm/crank revolution on the SW-W 500 and SW-W 750, with the gearbox tuned to keep crank-handle force within comfortable manual range across the capacity span.

More About This Product

The Pfaff-Silberblau SW-W (SG version) is the standard wall-mounted manual wire rope winch covering capacities from 80 kg through to 750 kg across five compact models. The "SG" designation refers to the special-gear configuration that distinguishes this range from the premium SW-W Alpha, with gear ratios tuned to provide consistent crank-handle feel across the capacity range and lifting speeds optimised for typical fixed-position lifting tasks. Each model ships with a pre-fitted galvanised wire rope sized for the rated capacity: 3 mm on the SW-W 80, 4 mm on the SW-W 125, 5 mm on the SW-W 300, 6 mm on the SW-W 500, and 7 mm on the SW-W 750. Top-layer rope lengths between 10 m and 30 m cover most fixed-position lifting requirements. A replacement crank handle accessory (article 39401040) is available separately for service or for installations where a longer handle is preferred for mechanical advantage.

Suitable Applications

The Pfaff-Silberblau SW-W (SG) is the standard wall-mounted manual winch for light and medium-duty fixed-position lifting across workshops, agricultural buildings, theatre and event rigging, equipment maintenance bays, and on-site construction. Light-duty applications for the SW-W 80 and 125 include theatre scenery rigging, agricultural feed and hatch operation, small workshop hoists, and light material-handling. The SW-W 300 and 500 cover mid-range workshop lifting, machine room access, and equipment positioning. The SW-W 750 is specified for the heavier end of fixed-position lifting where the load characteristics suit a compact wall-mounted solution rather than a free-standing winch. For higher capacities up to 1,500 kg, see the Pfaff-Silberblau MWS range. For the 300 kg – 1,000 kg range with an integrated load-pressure brake, see the Pfaff-Silberblau SW-W Alpha range. For console-mounted aluminium-housing winches with safety spring brake, see the SW-K GAMMA or SW-K LAMBDA ranges.

How to Use the Pfaff-Silberblau SW-W (SG)

1. Verify the mounting: Confirm the four wall-fixing bolts remain fully torqued and the wall substrate is undamaged. The mounting must support the rated capacity plus an appropriate safety factor.
2. Inspect the rope: Visually check the full working length of the wire rope for kinks, broken strands, surface damage, or wear concentrations. Remove from service if any defect is found.
3. Verify the crank handle: Confirm the crank handle is correctly fitted and locked in place. Check the handle for distortion or wear at the spindle interface.
4. Attach the load: Connect the working end of the rope to the load via a suitable rated hook, sling, or shackle. Ensure all connections are secure and any hook safety latches are fully engaged.
5. Verify the rope alignment: The rope should run cleanly from the drum through any guide or sheave to the load without rubbing against the housing or wall.
6. Lift the load: Crank the handle smoothly in the lift direction to raise the load. Avoid sudden starts or stops. Note the gear ratio differs by model: the SW-W 80 lifts 170 mm per crank revolution; the SW-W 750 lifts 35 mm per crank revolution.
7. Maintain a firm grip: Hand-cranked winches require the operator to maintain control of the crank handle throughout the lift cycle. Releasing the crank without securing the load can cause back-driving.
8. Secure the load before unattended use: If the load is to be left suspended for any extended period, transfer it to a dedicated load-holding support.
9. Lower the load: Crank the handle in the reverse direction at a controlled rate, maintaining a firm grip on the handle throughout descent.

Warning:
Wire rope winches are lifting devices and must not be used to lift, lower, or transport personnel. Never exceed the rated capacity stamped on the winch body. Never use a winch with damaged rope, distorted housing, or a worn / damaged crank handle. The winch is for vertical lifting from a wall mount only.

Safety Information

• Verify the wall mounting before each use — bolts torqued, wall substrate undamaged.
• Inspect the wire rope for the full working length each shift; remove from service at first sign of broken strands, kinks, or surface damage.
• Never exceed the rated capacity stamped on the winch body.
• Never use the winch to lift, lower, or transport personnel.
• Maintain a firm grip on the crank handle throughout lifting and lowering — uncontrolled back-driving of the drum can cause serious injury.
• Keep at least three turns of rope on the drum at full extension — never run the rope off the drum.
• Do not stand under the suspended load. Position yourself clear of the load path.
• Transfer the load to dedicated support before leaving it suspended for any extended period.
• Workplace operators must establish a Thorough Examination regime under LOLER 1998 / PUWER 1998 at intervals not exceeding 12 months.

Inspection and Maintenance

The SW-W (SG) is built for low routine maintenance with the rope, crank handle, and gearbox being the key inspection items. Before each use, inspect the wire rope for the full working length, verify the crank handle is firmly fitted and undamaged, and check the wall mounting. The gear mechanism benefits from periodic light greasing per the OEM datasheet schedule. Replacement wire ropes are available from CMCO in matched diameters and lengths — only manufacturer-specified rope assemblies should be fitted, since rope substitution affects the rated capacity. The crank handle (article 39401040) is available as a spare and should be replaced if any wear or distortion develops. WOLFF Onsite provides LOLER-certified Thorough Examination, spare parts, replacement rope sets, and full overhaul for the Pfaff-Silberblau SW-W range.

Optional Accessories

• Replacement crank handle (article 39401040): Direct-fit replacement crank for all SW-W (SG) winches in the range.
• Replacement wire rope assemblies: Matched diameter and length, pre-terminated for each capacity in the SW-W range.
• Wire rope pulley blocks (DSRB): Pfaff-Silberblau DSRB pulley blocks deflect the rope at 90° or 180° to reposition the working line or double the pulling capacity of the winch.
• Wall mounting plate sets: Reinforced mounting plates for installation on lightweight walls or partitions.
• Wire rope grease and corrosion protection: Service consumables for routine maintenance of the rope.
