Stahl ST Electric Chain Hoist

Facts About Stahl ST Electric Hoist Line

The ST chain hoist programme ranks among the world’s most distinctive and extensive ranges on offer. Users, crane manufacturers and systems manufacturers appreciate the robust classic which proves itself in operation day for day. It is powerful, reliable and undemanding as regards maintenance and power consumption. The supervised series production of the standard components brings you economic advantages. And in conjunction with the precise manufacture of off-standard components, the ST chain hoist is an acknowledged top-level quality product.

The modular system permits numerous combinations of sub-assemblies to achieve your individual solutions.

The ST series from STAHL CraneSystems is available in 9 load capacity variants for the load capacity range from 125kg to 5-tonne.

ST chain hoists can be used as stationary models with suspension hook or eye, with rigid suspension or with a push trolley. Or when completed by an electric trolley they are mounted on standard cranes, off-standard cranes or in systems manufacture. The technical highlight which makes the ST chain hoist one of the safest around is the direct suspension on the patented solid cast iron chain guide. The load is supported at the point where it engages.

Various off-standard designs are available for use in particular conditions. Two constructions optimise the effective hook height of all chain hoist models if required. The headroom of the short-headroom trolley and the extra short-headroom trolley is a reduced Standard ST chain hoist with electric trolley by 33 % and over 60 % respectively. For exceptional requirements, our experts in the engineering department will develop suitable customised solutions. Even in explosive atmospheres, you do not have to manage without the ST chain hoist. On request, nearly the entire chain hoist programme is available in explosion-protected design for Zone 1, Zone 21 and Zone 22. It’s no coincidence that Stahl is a market leader for explosion-protected lifting technology and crane components.

Models and Suspension Options

Different construction types and trolley variants for the ST chain hoist open up the most varied applications in crane and systems manufacture. Individually tailored to your specific requirements as stationary hoist or for use with a trolley. The trolleys are equipped as standard with one travel speed, as an option the motors can be supplied with two travel speeds. But in this matter too we are open to your requirements. Our chain hoists are known worldwide for their flexible and versatile use. Compact dimensions and extremely short approach dimensions help to make optimum use of the production shop.

Stationary Suspension Options

The standard stationary ST chain hoist has hook suspension. However, you can also choose eye suspension or rigid suspension.

The eye suspension is used when the stationary chain hoist is only rarely moved to a different location, while the low headroom permits long hook paths even in low-ceilinged rooms. If the ST chain hoist is to be permanently mounted, for example in systems manufacture, we recommend rigid suspension. Here too the extremely short headroom is of advantage. In addition, the rigid mounting prevents the chain hoist from swinging on the trolley.

Stationary Foot Mounting

In order to utilise space optimally in low-ceilinged rooms the ST chain hoist can be bolted from below onto a foot mounting.

Trolley Options

Push Trolley In the standard version, the ST05 and ST 10 1/1 chain hoists are suspended by eye or hook from the smooth-running push trolleys. Rigid suspension of the chain hoist is possible on request. The push trolley does not affect the low headroom of the hoist. Optional wheel arresters make your workplace safer.

DUE Articulating Trolley The DUE articulated trolley is available for frequent travel around bends and narrow radii. Depending on the radius of the bend, runway flange width or application it is equipped with one or two travel motors. The lateral guide rollers cause minimum wear. The DUE articulated trolley is designed for load capacities up to 6,300kg.

Standard Headroom Electric Trolley Even with the smooth-running electric trolley, the extremely short headroom permitting long hook paths is typical.

Short Headroom Electric Trolley The smooth-running electric trolley can also be combined with the ST short headroom chain hoist, reducing the headroom by a further 33%.

Explanation of Duty Cycle

%ED is how long the motor can run in a 10 minute period

40% ED means the motor can run for 4 minutes and then needs to rest for 6

20% ED means the motor can run for 2 minutes and then needs to rest for 8
