SHW 8 卷扬机

Top technology for the heaviest of loads and high demands

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 160,000 kg. Its strong hoist motors and robust, low-maintenance design make it ideal for tough everyday use. Compared to wire rope hoists, winches only need a few rope reevings even for high loads, making a very compact construction possible.
To enable a variety of different economical solutions, there are three motors up to 38 kW with two speeds in a ratio of 1:6 available for the SHW 8 winch. For higher ease of use, there are six hoist motors up to 98 kW with stepless speed control. All travel drives are equipped as standard with soft start. The SHW 8 winch is available on request with high-performance frequency inverters or with individually adapted speeds.

The winch programme is also available in explosion-proof design for Zone 1, Zone 2, Zone 21 or Zone 22.

Series components from the SH range, field-proven in thousands of applications
Modular design for cost-effective individual solutions, simple transport and speedy erection
Versatile drive technology meets demanding specifications: 3 hoist motors up to 38 kW with two speeds in a ratio of 1:6 and 6 hoist motors up to 98 kW and stepless speed control
All travel drives with smooth starting characteristics
Overload cut-off pre-set during manufacture
Compact headroom thanks to innovative rope drive design

The modular construction of the SHW 8 winch makes it possible to transport the winch in its individual parts and to assemble it again on site quickly.
This SHW 8 winch is designed for particularly high speeds and equipped with tool grippers.
The innovative design of the rope drive enables the very low headroom of the SHW 8 winch.
The SHW 8 winch is particularly maintenance-friendly as its clean assembly grants the service technician easy access to all important components.

Models

The different models and trolley variants allow not only a wide variety of uses, but also very individualised solutions tailored to specific requirements.

Stationary model

The SHW 8 winch can be used as stationary hoisting or towing equipment, for example in systems manufacture. Depending on the application, the rope lead-off angle, the attachment of the hoist and the mounting position of the hoist motor can be varied.
OE double rail crab

The OE double rail crab is intended for use on double girder overhead travelling cranes. The extremely compact construction makes very low approach and headroom dimensions possible and the available space can thus be used to the full. The double rail crab is available with various track gauges for the whole load capacity range and automatically compensates for any unevenness of the cross travel runway.
Double-grooved rope drum (True vertical lift)

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 or with travel carriages.
Double-grooved rope drum (Optional reeving for multiple load pick-up points)

The model with double-grooved rope drum (right-/left-hand thread) is used for many lifting and towing tasks where the load must be picked up at more than one point and true vertical lift is required.

Technology

The modular design of the SHW 8 winch allows a virtually endless combination of components: therefore – as with the SH wire rope hoist – individual solutions are possible on the highest level of quality.
- All mechanical components are bolted
- Dismountable for transport
- Lifting eyes provide better handling
Paint
- Standard paint treatment as per RAL 7021 greyish black
- High-quality primer and top coats for standard applications
- Off-standard paint treatment for outdoor use or corrosive ambient conditions
- Shade as per customer’s requirement
Overload cut-off
- Permanent electronic monitoring of the suspended loads
- Limitation of the maximum load by load measurement at the rope anchorage in the case of multiple reeving or at the gearbox
- Adjusted over load cut-off at pivot-mounted gearbox, depending on hoist size
SLE/SMC control and motor management
- Condition monitoring as standard
- Inching operation is suppressed thus reducing stress
- All common control voltages available
- High degree of safety thanks to overdimensioned contactors
- Monitoring of the temperature of the hoist motor and travel motor
Brake
- Low-maintenance, asbestos-free double-shoe brake; no readjustment necessary
- Long service life thanks to generously dimensioned brake
- Brake easily accessible for inspection from outside
- Motor management ensures low wear
- IP 65 protection
Hoist motor
- Pole-changing or frequency-controlled three-phase motors
- ISO classification according to FEM/ISO standards, high duty cycle and switching operation frequency
- IP 55 protection, thermal class F
- Good motor cooling, maintenance-friendly
- Temperature control by ptc thermistors
Hoist gear
- Versatile gear ratios for individual speeds
- Long service life through oil lubrication, with minimum maintenance
- Hardened and ground gears
Gear limit switch
- Standard emergency hoist limit switch for top and bottom hook position
- As an option, up to eight switching elements can be fitted to the switch. This permits for example further stopping positions and operational limiting in bottom hook position.
Rope drive
- Designed for high protection and life time
- Flexible, galvanized special rope with safety factor >4
- In the standard design with 2 ropes, no hook travel
- Wear-resistant return sheaves, fine machining provides rope-friendly grooves in rope drum
- Robust bottom hook block with low headroom in spite of large dimensioning of hook

Options and features

Although they are already first-class in their standard design, you can make the hoists even safer, more economical and more convenient with a range of mechanical, electrical and electronic options. They simultaneously improve performance, prolong service life and make it possible to adapt the hoist individually to specific requirements.

Here are some of the options frequently used.

Control pendant
- Robust control pendant with EMERGENCY STOP palm button and control cable
