Winches for building maintenance

The Syncrowinch model SW 500 has received EC-type test approval from TÜV, Berlin. It is designed and built to meet and exceed the European Safety Standard EN 1808 for Building Maintenance Units (BMU).

The SW 500 hoist is manufactured out of top quality materials. All required safety devices are integrated. No loose parts ! The compact design of the SW 500 allows an easy installation to the gondola.

The main frame of the SW 500 hoist incorporates all components such as twin drum drive assembly, rope layering device, safety block with shock absorber, overload and underload sensor, top limit and ultimate limit switch, tilt sensor, terminal box with multi-pin connecting plug to connect control box.

The main frame acts as a stirrup which is fixed by 2 fastening points to the floor of the gondola. A third fastening point is located at the upper guard-rail for lateral stability.

Compared to a traction type hoist, the SW 500 powered twin grooved drum system with differential and rope layering device ensures a much longer rope life and eliminates the common risk of rope jam.

The annual inspections are simple and few replacement parts are needed.

Following safety features are included in the SW 500 hoist:

• overload and underload sensor;
• empty drum limit switch;
• tilt sensor and brake;
• slack rope sensor with emergency brake on each suspension rope;
• shock absorber for emergency stop;
• speed limiter for manual controlled descent; and
• top and ultimate limit switch.

Technical data of the SW 500:

• lifting capacity: 500 daN;
• maximum rope length: 160 m Ø 6,5 mm DIN 5038x;
• average lifting speed: 9 m/min;
• total weight (without rope): 90/110 kg depending on drum size;
• weight of 6,5mm rope per 100m: 18 kg;
• power supply : 3 x 400 V 50 Hz / 1 kW; and
• overall dimensions: depending on drum size

Optional equipment:
