■ Series components of the SH series proven thousands of times over ■ Modular design ■ 3 hoist motors up to 38 kW with two speeds in a ratio of 1:6 ■ 6 hoist motors up to 200 kW and stepless speed control ■ All travel drives with soft start ■ Overload cut-off device is already pre-set during manufacture ■ Compact headroom thanks to innovative design of the rope drive The SHW 8 winch program is based on the tried-and-tested SH wire rope hoist program and is designed for the high-load bracket up to 250,000 kg. Its strong hoist motors and robust, low-maintenance design make it ideal for tough...

Double-grooved rope drum If true vertical lift is required, we recommend this model with double-grooved rope drum (right/left-hand thread). This version can be used both in stationary form and with trolleys. Reeving without lateral hook movement Double-grooved rope drum The design with double-grooved rope drum (right/left-hand thread) is used for many lifting and towing tasks where a multipoint load attachment is required and no lateral hook movement during lifting and lowering is desired. Optional reeving with multipoint load attachment S.W.L. to* Reeving Stationary OE double rail crab...

It is a reassuring feeling to know what convincing technology is inside every SHW 8 winch. The largely maintenance-free components of the modular winch from proven series components are matched to each other optimally. They guarantee constant performance, high efficiency and long service life. Flexible drive technology, the high-performance gear unit with versatile ratios and standard safety components or many additional options increase safety at the workplace. ■ Pole-changing or frequency-controlled three-phase motors ■ Classification according to ISO, high duty cycle and high switching...

STAHL Kit ■ Standard emergency hoist limit switch in highest and lowest hook position ■ Switch can be equipped optionally with up to eight switching elements. This allows, for example, further holding positions and the operational limit stop in lowest hook position to be realised. ■ Designed for high safety and long life ■ Flexible, galvanised special rope with rope safety factor >4 ■ Standard version with 2 ropes, no lateral hook movement ■ Wear-resistant return sheaves, rope-friendly rope drum grooves thanks to fine machining ■ Robust hook block with low headroom in spites of large hook...

Although they are already first-class in their standard design, you have the possibility to make your SHW 8 winch even safer, more economical and more convenient with a range of mechanical, electrical and electronic options. With the add-ons, you improve the performance of the wire rope hoist and adapt it individually to your requirements. ■ The brake air device for manual release of the hoist brake and to lower the load in the event of a power failure. ■ For hoist motors up to 63 kW and 50 Hz additional double-shoe brake according to DIN 15435 with external brake spring ■ For hoist motors...

Engineering means innovation and individuality. It is the task of our experts to redefine the lifting and moving of loads for complex requirements time and again. They constantly develop modern, individual custom and off-standard solutions from one of the largest ranges of standard components available. Virtually no other manufacturer of hoisting and crane technology can offer this variety of precisely engineered special solutions with such quality and such efficiency. The modular SHW winch programme forms the basis for a wide variety of solutions. Specific system solutions adapted...

Example 1 Power station cranes with two SHW 8 winches Two power station cranes from STAHL CraneSystems, each with a lifting capacity of 80 tonnes, are used by an Icelandic energy company for installation and maintenance of 47.5 MW hydropower turbines. Working in tandem mode, which is realised via mechanical coupling of the cranes and trolleys, the cranes are able to lift the hydropower turbines with a total lifting capacity of 160 tonnes and transport them out of the shaft for maintenance work. The cranes have a span of 13.8 m and a lifting height of 27 m. The SHW 8 winch from STAHL...

Example 2 Dam winch for S.W.L. of 100 tonnes The Kishanganga hydroelectric power station in India lies more than 2,400 metres above sea level. A winch developed by STAHL CraneSystems engineers is used to lift and lower the 100 t sluice of the dammed Kishanganga River. The stationary SHW 8 winch with a load capacity of 2 x 60,000 kg is designed with two rope drums and a gearbox. For even distribution of the weight, the hoist is designed with a reeving of 2 x 12/2-1. The double symmetrical arrangement ensures absolute synchronisation of the two load hooks. In order to compensate tolerances...

Example 3 Inspection crane in hydroelectric power station Due to extensive modernisation, a new crane system has been commissioned at a Swiss hydroelectric power station. An SHW 8 winch from STAHL Crane-Systems with a lifting capacity of 85 tonnes and an additional auxiliary hoist, an SH wire rope hoist for a safe working load of 10 tonnes, work parallel to an existing winch. The two new hoists have a maximum lifting height of 40 metres. The system is operated with a special control system that enables particularly precise and fine control of the crane. The travelling and lifting speeds...

The explosion-proof winch SHW 8 Ex ATEX STAHL CraneSystems is known internationally as a specialist for explosion protection and considered one of the world market leaders in explosion protection technology. The safety of people and machines in potentially explosive gas and dust atmospheres is our top priority. We make no compromises here. As a developer of numerous innovations in this field, we have influenced the progress in crane technology perceptibly. Experience and know-how from many decades, our own fundamental research and development, approvals from the German national metrology...
