Pfaff-Silberblau MWS Wall-Mounted Wire Rope Winch

Model MWS | Capacity 150 kg – 1,500 kg | Wall-Mounted Manual Winch | Five Capacity Grades | Wire Rope 4 mm – 10 mm | Top-Layer Rope Length 12 m – 35 m | CE & UKCA Marked | Made in Germany

The Pfaff-Silberblau MWS is the broad-range wall-mounted manual wire rope winch, covering capacities from 150 kg through to 1,500 kg across five standard models — the largest spread of any wall-mounted winch in the Pfaff range. Each model is matched with the appropriate wire rope diameter, from 4 mm on the 150 kg and 300 kg up to 10 mm on the heavy-duty 1,500 kg, with top-layer rope lengths between 12 m and 35 m. The robust hand-cranked drum mechanism is built for steady industrial use across factory, warehouse, plant room and on-site lifting.

Key Features

• Five capacity grades: 150 kg, 300 kg, 600 kg, 1,000 kg, and 1,500 kg covering everything from light workshop lifting to heavy industrial fixed-position duty.
• Rope diameter matched to capacity: 4 mm (150 / 300 kg), 6 mm (600 kg), 8 mm (1,000 kg), 10 mm (1,500 kg) — the rope diameter is sized for the rated capacity with appropriate safety factors.
• Gear ratio matched to load: Lift speed ranges from 122 mm/rev on the MWS 150 (light load, fast lifting) down to 14 mm/rev on the MWS 1500 (heavy load, controlled lifting). The gearing keeps crank force manageable across the capacity range.
• Wall-mounted hand-crank design: Direct-acting manual lifting from a fixed wall installation. No power supply, hydraulic feed, or compressed air required.
• Pre-fitted wire rope: Each winch ships ready to use with matched rope diameter, length, and termination — no separate rope assembly required.
• Top-layer rope lengths up to 35 m: The MWS 300 provides the longest standard lift on the range; the heavy 1,500 kg model still provides 21 m of working rope.
• Robust mechanical construction: Industrial-grade build for steady daily duty cycles in factory, warehouse, and on-site applications.

Technical Specifications

Capacity is the 1st-layer rated load. Lift per crank revolution applies at the top rope layer and reduces as the drum fills. Note the MWS 150 is geared for high-speed lifting (122 mm/rev) at light loads, while the heavy MWS 1500 is geared for high-force low-speed lifting (14 mm/rev) — pick the capacity carefully as it changes the lifting feel significantly.

More About This Product

The Pfaff-Silberblau MWS is the broad-range wall-mounted manual wire rope winch covering capacities from 150 kg through to 1,500 kg across five standard models. This is the largest spread of any wall-mounted winch in the Pfaff range, making it the go-to choice when a single supplier solution is required to cover light-duty workshop lifting at one end and serious industrial fixed-position lifting at the other. Each model is matched with the appropriate wire rope diameter — 4 mm on the 150 kg and 300 kg, 6 mm on the 600 kg, 8 mm on the 1,000 kg, and 10 mm on the heavy-duty 1,500 kg — and ships with top-layer rope lengths between 12 m and 35 m depending on model. The MWS series is built around a robust hand-cranked drum mechanism designed for steady industrial use across factory, warehouse, plant room, and on-site lifting applications.

Suitable Applications

The Pfaff-Silberblau MWS is the standard wall-mounted manual winch for fixed-position lifting across the broadest capacity range in the Pfaff catalogue. Light-duty applications for the MWS 150 and 300 include workshop hoists, agricultural hatch openers, small-scale theatre and event rigging, and light equipment positioning. Mid-range applications for the MWS 600 cover machine room access, heavier door and hatch operation, and goods-lifting in light industrial environments. The heavy MWS 1000 and 1500 are specified for serious fixed-position industrial lifting: structural component positioning, machine installation on building sites, agricultural feed and material handling, and barrier / gate operation where powered solutions are not practical. 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 range.

How to Use the Pfaff-Silberblau MWS

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. 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.
4. 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.
5. 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 MWS 150 lifts 122 mm per crank revolution; the MWS 1500 lifts 14 mm per crank revolution.
6. 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. Hand-cranked winches are designed for active lifting, not long-term load anchoring.
7. Lower the load: Crank the handle in the reverse direction at a controlled rate. Maintain a firm grip on the crank handle throughout the 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 or distorted housing. 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.
• 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.
• Maintain a firm grip on the crank handle throughout lifting and lowering — uncontrolled back-driving of the drum can cause serious injury.
• 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 MWS is built for steady industrial service with routine maintenance focused on the rope and gearbox. Before each use, inspect the wire rope for the full working length for kinks, broken strands, or surface damage; check the wall mounting; verify the crank handle is undamaged and rotates smoothly. 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. WOLFF Onsite provides LOLER-certified Thorough Examination, spare parts, replacement rope sets, and full overhaul for the Pfaff-Silberblau MWS range.

Optional Accessories

• Replacement wire rope assemblies: Matched diameter and length, pre-terminated for each capacity in the MWS 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 where direct fixing into structural masonry is not possible.
• Wire rope grease and corrosion protection: Service consumables for routine maintenance of the rope.
