STAHL CraneSystems is adding an innovative, sophisticatedchain hoist programme to its tried and tested classics: the SC chain hoist . Our engineers, working in a team ofexperienced, practically orientated specialists, have
developed the upgradable SC chain hoist, equal to thechallenges posed today and in the future. Naturallyit complies with the latest RoHS directives and is par - ticu larly efficient as regards energy consumption andmaintenance. We are convinced that users, cranebuilders and systems manufacturers will appreciate thisextension to the product range.
The SC chain hoist is of modular design and plug-in
components make it ready for use in next to no time.STAHL CraneSystems SC series is at your d isposal in three variants for the S.W.L. range from 63 kg to 2,500 kg .Further variants for higher capacities are in preparationand will follow shortly. The chain hoists can be used asstationary hoists with suspension hook, eye or rigidsuspension. Mobile chain hoists are equipped with field-proven push and electric trolleys in various con figu-rations. The technical highlight that distinguishes the SCchain hoist is the patented 5-pocket chain sprocket. Anadditional cog provides extra positive locking to support the vertical chain link. This reduces wear and ensurespermanent safety. The whole chain guide is manufac- tured of robust spheroidal graphite cast i ron.
A further advantage of the SC chain hoist is the arrange-ment of brake, slipping clutch and motor on one axis.
SC05 chain hoist
The slipping clutch is not in the power flux during brakingand thus has no impact when the system has come to astandstill. In addition, a wider range of hoisting speeds isavailable, while the safe working load has been in-
creased by 25 %. The impressive straight-lined design ofSTAHL CraneSystems SC chain hoist and the syste maticcontinuation of the modular construction principle form the basis for developing and manufacturing purpose-builtand engineering solutions for individual customers.

Developed by experts for experts
Weve kept the good things, just added more of them. Our engineers, drawing on their many years of practical experience, were once more able to developimportant innovations to meet your requirements. The spectrum of chain hoist types available is now even further differentiated, more f lexible and adaptable.
Increased operational reliability, performance and cost-effectiveness, those are the features of the new chain hoist . Here are the highlights of thenew SC chain hoist:

Straight linesThe up-to-date straight-lined design of the SC chain h oist signalise s functi onal ityand maximum flexibility. It is the basisfor customer-specific, purpose-built andengineering solutions. The clear, right-angledside faces and compact dimensions make itpredestined for crane and systems building.It is particularly easy to adapt to the mostvaried requirements. Small, compact,straight-lined: that is not just visuallyattractive, but above all a direct andefficacious route to countless solutions.

Precise slipping clutchIn the new SC chain hoist, brake, slippingclutch and motor are arranged on one axis.The slipping clutch is not in the power fluxduring braking and thus is not active when the s yste m has com e to a standstill . The useof partially synthetic oil keeps the frictioncoefficient of the clutch constant. Optimumresponse is reproducible thanks to preciseadjustment by means of a fine thread.
Drive force
Motor
Gear
Brake
Slipping clutch
Maintenance-free brakeThe asbestos-free brake is situated inside thehousing and thus protected from environ-mental influences. The condition of the brakelining can be checked at any time through anaxial drillhole. Direct action on the load isguaranteed by the new brake arrangement.
Plug-in componentsThe SC chain hoist is of modular design, allcomponents and electrical connections have
plug connections. This means that this chainhoist is ready for use in a flash. Modifications,retrofitting and upgrading can be carried outwith minimal downtimes.
All-metalOnly high-tensile powder-coated aluminium isused for the robust housing of the SC chainhoist. The special aluminium alloy is virtuallyas strong as steel. Plastic parts in thehousing have consciously been avoided.
Braking force

Frequency controlled electric trolleyYou can choose travel motions with predefinedor stepless speeds for the electric trolley.Frequency control ensures smooth starting andbraking characteristics.
Hoist limitingThe SC chain hoist is equipped as standardwith a hoist limit switch for top and bottomhook positions. A rocker switch integrated into the chain guid e ensure s tha t cu t-of f is relia ble.
Extended range of hoisting speedsThe SC chain hoist programme is even more
efficient and supplements our portfolioperfectly. A greatly extended range of hoistingspeeds is available; and this in conjunctionwith a 25 % increase in load capacity.
Robust gearFlexible use in the most varied fields, thatswhat characterises all chain hoists fromSTAHL CraneSystems. You can rest assured that the gear of th e SC c hain hois t is d esignedfor the most stringent requirements anddemanding applications. The fully helicalgearing always guarantees even, smoothrunning.

Flexible controlAs standard, the SC chain hoist is equippedwith a p.c.b. control divided into a powersection with main contactor and transformerand a control section. The modules areplug-in and exchangeable, facilitating simple,fast commissioning and high flexibility.In particular crane and systems builders willappreciate this characteristic. STAHLCraneSystems will continue to offer thefamiliar conventionally wired contactorcontrol in the future in order to satisfy globalrequirements.
Innovative chain driveYou will find the new patented 5-pocket chainsprocket (EP 2 047 141 B1) and the field-proven, robust chain guide in spheroidalgraphite cast iron convincing. They are thebasis for long service life and reliableoperation even under extreme conditions.
The five asymmetrically arranged cogs of thenew chain sprocket provide extra positivelocking. This reduces the bending stress on the vert ical chain link wh en the chain isunder load.

The models and trolley variants
Hook
Foot mounting
Eye Rigid suspension
Different construction types and trolley variants for the SC chain hoist open up the most varied applications in crane and systems building. Individually tailored to your specif ic requirements as stationary hoist or for use with a trolley. The tro lleys are equipped as standard wi th two travel speeds, as anoption the frequency-controlled motors can also be supplied with stepless travelling speeds. Our chain hoists are known worldwide for their flexible andversatile use. Compact dimensions and extremely short approach dimensionshelp to make optimum use of the production shop.
Suspension for stationary versionThe standard stationary SC chain hoist hashook suspension. However you can also
choose eye suspension or rigid suspension.Eye suspension is used when the stationarychain hoist is never or only rarely moved to adifferent location, while the low headroompermits long hook paths even in low-ceilingedrooms. If the SC chain hoist is to bepermanently mounted, for example in systemsbuilding, we recommend rigid suspension.Here too the extremely short headroom is ofadvantage. The rigid mounting also prevents the chain ho ist swinging on t he tr olley.
Foot mounting for stationary versionIn order to utilise space optimally inlow-ceilinged rooms the SC chain hoist canbe bolted from below onto a foot mounting.

Its reassuring to know what convincing technology isconcealed in the innovative SC chain hoist. The largelymaintenance-free components of the modular chain hoistare optimally matched to each other. They guaranteeconstant performance, high efficiency and long servicelife. An important feature of the SC chain hoist is the newarrangement of brake, slipping clutch and motor on oneaxis. This means that the slipping clutch is not in thepower flux during braking. A further innovation is thepatented 5-pocket chain sprocket in spheroidal graphitecast iron, which greatly reduces the bending stress on the vertical chain links under load.

The factsSTC chain hoist as [extra] short headroom trolleyIf you do not want to lose even a millimetre of lifting height, STAHL Crane-Systems SCK extra short headroom trolley is just the thing for you. Theconstruction of the short headroom trolley itself saves a tremendous amountof space and reduces the headroom by 33%. The extra short headroom trolleywith its headroom reduced by 60% achieves maximum hook paths particularlyin extremely low-ceilinged rooms and fully deserves its name. The distancefrom the underside of the beam to the bed of the hook, just 210 mm at a loadcapacity of 5,000 kg and 185 at 3,200 kg, is extremely low and unique atpresent. The chain hoists used here, mounted vertically, are based on standardcomponents of STAHL CraneSystems SC chain hois t programme.
The patented chain drive is unique. Two separate chains running in synch act on asingle bottom hook block. The load is lifted and positioned without swinging orvibrating.
