ST Chain Hoist

The loyal companion for everyday tasks

The ST chain hoist programme ranks among the most distinctive and comprehensive on offer worldwide. It is strong, reliable and modest when it comes to maintenance and energy consumption. The modular system enables innumerable combinations of the subassemblies for customised solutions. With 6 variants available, the ST chain hoist covers the lifting capacity range from 125 kg to 6,300 kg. The portfolio is supplemented by special models such as the STK extra short headroom trolley and the STD dual chain hoist for long material and lifting beams.

The chain hoists are also available in explosion-proof design for Zone 1, Zone 21 and Zone 22.

Models

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

Slide title

Push trolley

In standard version, the ST 05 and ST 10 1/1 chain hoists are suspended by eye or hook from the smooth-running push trolleys. A rigid connection with the chain hoist is possible on request. This rigid connection is standard in the ST 20 to ST 60 chain hoists. The push trolley does not affect the low headroom of the hoist. Optional wheel arresters make your workplace safer.

DKE articulated trolley

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

“Standard headroom” electric trolley

Not one millimetre was given away in the design in order to enable large hook paths even at standard headroom.

Button
Slide title

“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 %.

Button
Slide title

STK short and extra short headroom trolley

The construction of the short headroom trolley itself saves a tremendous amount of space. The body of the chain hoist is mounted at an angle, meaning that no return sheave is required. This reduces the headroom by 33 %. The extra short headroom trolley with its headroom reduced by 60 %, by contrast, achieves maximum hook paths, which is particularly beneficial in extremely low-ceilinged rooms. It fully deserves its name. The extremely short distance from the underside of the beam to the bed of the hook is just 210 mm at a load capacity of 5,000 kg and even just 185 mm at a load capacity of 3,200 kg.

The STD dual chain hoist

The STD dual chain hoist is ideal for long material and lifting beams that need to be picked up at two points. It is equipped with two load chains, which are moved synchronously by a hoist motor. There are various versions of the STD dual chain hoist available for different requirements and space situations.

Slide title

STB Big Bag design

The Big Bag version is designed for load capacities up to 3,200 kg. Its special feature is the free choice of the distance between chain hoist and load hook which makes lifting bulky loads or Big Bags up to top hook position possible without hindering edges such as trolley, chain hoist or chain box.

Suspension for stationary version

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. Electrical hoists, such as the ST chain hoist, are designed for various applications. 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 swinging on the trolley.

Foot mounting for stationary version

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