Premium Hoists are available in the following product groups:
Premium Hoists
Technology that moves.
Devices that work precisely and reliably under the highest loads have borne the HADEF name for over 100 years.
The Premium line consistently continues the tradition of the highest product quality and safety.
Robust constructions and well-engineered assemblies “Made in Germany” guarantee the longest possible service life, even under extreme operating conditions.
The modular building block system
With the AK series, HADEF has created a modular “building block system” for hoists.
The basic model of this chain hoist is used here in many variants: as a trolley, reel or electric trolley, with different load capacities.
The variants of the AK series
66/04 AKS
stationary
66/04 AKR
with push travel trolley
66/04 AKH
with hand geared trolley
66/04 AKE
with electric trolley
Quality to the smallest detail
Top technology consistently thought through and produced for maximum reliability and durability
All components of the HADEF Premium line are designed for durability and high loads. Thanks to the use of high-quality materials and modern manufacturing processes, the devices in the Premium Line are particularly hard-wearing and fail-safe.

Advantage through research
Greater economy through innovative research into wear reduction.
The forces acting on the materials are measured in complex test procedures. The results of these tests are the basic data for our designers, whose task it is to continue to minimize wear and tear on the individual assemblies through optimal force distribution, with the aim of improving each new product generation a little bit.
chain comparison
chain wear in %
Number of load cycles (lifting and lowering)
The diagram shows the low wear of the calibrated HADEF special chain compared to tempered and case-hardened DIN standard chains.
total lifetime cost
Acquisition costs including wearing parts, service and labor costs are not taken into account
Operating time in years corresponds to 8 full load hours / day
The diagram shows the resulting cost advantage of HADEF chain hoists with calibrated special chains.
