01
Choose the hook for each load
Use a single hook for routine lifting, or choose a main and auxiliary hook crane when the same bay handles both large equipment and smaller components.
02
Match the crane to the work cycle
A5 and A6 selections let the bridge, lifting mechanism and travel equipment follow the frequency and severity of the lifting task.
03
Cover the complete workshop bay
Bridge travel and trolley travel move the hook between receiving, assembly, storage and maintenance positions on one overhead runway.
01 / APPLICATIONS01 02 03
Move heavy work through the workshop.
Equipment assembly and maintenance
Move motors, gearboxes and complete machines into position. Add an auxiliary hook when smaller components need a separate lifting mechanism.
Industrial storage and dispatch
Transfer heavy finished equipment between storage and loading positions. Outdoor service can be specified for an exposed runway.
For a 20/5 t crane, the main hook is rated 20 t and the auxiliary hook 5 t. The technical offer defines the permitted hook combinations.

Each row is a complete selection. A slash identifies main and auxiliary hook values. Capacity, span, duty and speeds stay together; heavy configurations use their own geometry and duty.
03 / EQUIPMENT VIEWS
See the bridge and winch trolley.
Compare the complete crane arrangement with workshop views to see the main girders, trolley and hook system.
04 / CONFIGURATION
Select the load, hook arrangement and working speed.
A clear starting point is your largest load, working span and required lifting height. The crane package can then be matched to the handling cycle.
Single hook or main and auxiliary hooks
Standard selections include 5 and 10 t single-hook cranes, plus 16/3.2, 20/5, 32/5 and 50/10 t main/auxiliary arrangements. Each hook retains its own rating.
Duty and lifting speed
Choose the duty with the lifting cycle. For example, the 16/3.2 t arrangement has 7.9 m/min main hoisting at A5 and 10.7 m/min at A6, with a 14.6 m/min auxiliary hook.
Operator position and travel control
Select cabin, pendant or radio control to suit visibility of the load and the production route. State any requirement for slow positioning or variable-frequency travel.
Heavy lifting and destination supply
Larger configurations use their own spans, speeds and duty classes. Match the electrical package to the destination voltage, frequency and indoor or outdoor operation.
05 / PURCHASING & DELIVERY

Answers for your QD crane purchase
Find the arrangement, equipment options and order information that suit your application.
When should I choose a QD winch-trolley crane?
QD suits workshop lifting where the load and operating cycle call for a winch trolley on a double girder bridge. Compare the selected duty and speeds with an LH electric-hoist crane when choosing the lifting package.
What does 32/5 t mean?
It identifies a 32 t main hook and a 5 t auxiliary hook. It is not a 37 t hook rating. The order defines whether the hooks can operate together and the permitted load case.
Which standard capacities and spans can I compare?
The standard group includes 5, 10, 16/3.2, 20/5, 32/5 and 50/10 t selections, with 10.5–31.5 m spans. The configuration table pairs capacity, duty, span, lifting height and hoisting speeds.
How do A5 and A6 affect the crane?
Duty follows the load spectrum and lifting frequency. A5 and A6 versions can have different hoisting speeds, structural details, crane masses and wheel loads. Select the duty with your typical load and operating hours.
Can you supply a crane above 50 t?
The QD family includes heavy main/auxiliary configurations from 75/20 to 450/80 t. These use capacity-specific geometry and mechanisms; for example, the 450/80 t selection has a 20.8 m span and A1–A3 duty.
Can I use the same crane indoors and outdoors?
The operating environment is specified with the order. For an outdoor runway, include the wind, rain, temperature and corrosion conditions so the electrical protection, coatings and parking arrangement can be selected.
What information is enough to get a price?
Send the maximum lifted load, span, lifting height and lifting frequency. Include the destination power supply, preferred control and whether rails, power supply equipment, installation or shipping are required in the offer.
How are delivery, warranty and certification confirmed?
The offer identifies the selected crane, dispatch schedule, warranty terms and required inspection or conformity documents. Production, international transport and site installation are scheduled as separate parts of the order.
