PRACTICAL PRODUCT ANSWERS
DAESAN DSN chain block questions.
What capacities are available in the DSN range?
The documented range runs from 0.5 t to 40 t across 14 configurations. The selector lists each exact model with chain falls, headroom, load chain and range availability. A shortlist is a specification aid; the complete lifting arrangement still needs competent review.
What is the difference between DSN2 and DSN2N?
Both are rated 2 t. DSN2 uses one chain fall, 7.9 × 23.0 mm load chain and 380 mm reference headroom C. DSN2N uses two falls, 6.3 × 19.1 mm load chain and 430 mm reference headroom C. The assemblies and spare parts must be matched to the exact model.
Can I request more than 3 m of lift?
Yes. Enter the required lift above 3 m and the hand-chain drop if known. Extended lifts and optional fitments require configuration review and quotation. The manufacturer reference lift used for published mass may differ from the supplied lift.
How do I get a chain block price or delivery date?
Select a model, enter lift, quantity and application details, then add it to your quote request. Include your delivery location and required date. Regularly stocked describes the catalogue range; pricing, current availability and lead time are confirmed with quotation.
Continue to the product quote request →Where can I find the DSN manual and product guide?
The document library links to the manufacturer operation and maintenance manual, the Cooper DSN product and support guide, and the available permit certificate page. Use the documents with the exact model and configuration.
Open DSN manuals and documents →What SABS approval evidence is available?
The available permit certificate page is 11894/18580 and references SANS 1594:2007. Integral permit schedules are not available here, so individual model coverage must be confirmed against those schedules. Do not infer approval of every configuration from the range name.
Read the evidence and its limits →Where can I read about choosing a different hoist type?
Cooper Group hosts the equipment-selection guidance. Use that resource to frame your application, then return to Engineering Supplies for the relevant product specification and purchase enquiry.
