ELECTRIC WIRE ROPE HOISTS

Now available with approvals for Class 1, Division 2, Groups A, B, C & D, Temperature Class T4

The SH Ex wire rope hoist

The SH Ex wire rope hoist is a leader in lifting and crane technology all over the world. Precision engineered, these hoists are built for reliable operation, high efficiency, and long service life.

Operators, crane manufacturers, and system manufacturers benefit from the hoist’s modular design that allows configuration of the hoist and crane system to meet exact application needs. Complete with a low-headroom trolley, the STAHL SH Ex is ideal for applications with space limitations.

The SH Ex is available for load capacities from 1000 lbs to 30 tons in five frame sizes with 26 load capacity variants. These wire rope hoists are available as deck mount models, monorail trolleys, and double girder trolleys for standard cranes, customized cranes, or special systems.

Various customized designs are available for use in certain environmental conditions. IP66 or NEMA 4/4X protection is available for outdoor hoists without a protective roof or if the hoist is exposed to water. If the risk exists for condensation formation or extremely low temperatures, panel heaters can be added. The SH Ex wire rope hoist can even be configured to effectively function in explosive atmospheres. Upon request, the entire hoist is available in an explosion-protected design for Zone 1, Zone 2, Zone 21, Zone 22, as well as Class I, Division 2, Groups A, B, C & D, Temperature Class T4. We are a global market leader with decades of experience.

The SH Ex wire rope hoist

TDC Twin Drive Design The TDC Twin Drive Design is the uncompromising solution for hoists complying with DIN EN 14492-2, Annex B. Hoists in TDC design are intended for the transport of molten metals and for use in high-risk applications: acids, alkalis, gases, or transport over gas and acid pipelines. They are equipped as standard with two motor-gear units. Both motors are always synchronously controlled. The brakes mounted on the two motors are designed so that in an emergency each one is capable of braking or holding the load by itself. The two brakes are activated in conjunction with one another and act as operating and holding brakes. On twin drive design hoists, all drives are monitored by STAHL CraneSystems condition monitoring systems.

SH Ex wire rope hoist and crane components in explosion-protected design for extremely low temperatures

In winter, temperatures can fall to -67 °F in many regions of the world. This can affect electronics, mechanics, and the crane component materials. STAHL CraneSystems has developed a non-standard solution especially for an extremely low temperature range.

The hoisting gear and control of the wire rope hoist are in thermally insulated housings. As soon as external sensors measure temperatures below -5 °F, the explosion-protected panel heater in the housing switches on. Panel heaters in all motors reliably prevent icing, condensation, and material embrittlement.

The crane system can be radio controlled. However, at temperatures below -4 °F, the control switches automatically from radio to manual operation. If temperatures drop below -40 °F, the crane switches off automatically.

The catwalk along the crane bridge is equipped with a handrail on both sides for safe maintenance work in snow and ice. The platforms over the crane endcarriages protect the travel drives and facilitate climbing onto the trolley.

�� Wire rope hoist and crane compo-nents in explosion-protected design for Zone 1�� ATEX and IECEx certified�� Automatic cut-off at -40 °F, storage

down to -58°F when shut down�� Thermally insulated housings for
