The actuators on various mobile hoists have failed suddenly and without
warning. These failures have caused sudden, uncontrolled dropping of the
hoist boom and, on some occasions, serious patient injury.
Horcher equipment is categorically not affected by the inherent design issues
detailed in the above alert relating to electrical actuators
Please look at a copy of the latest Certificate of our Diana Lift Series,
issued by Berlin Cert (Berlin Cert is a part of the Technical University
of Berlin, Testing Centre for Medical Devices).
The Diana Lift Range is the only product that we manufacture that works with
a linear actuator as described in the MHRA Alert. All our products are tested
and monitored by Berlin Cert. They also additionally perform Lifetime Tests,
in which the product has to run a One Million Cycle test. In Addition to
these tests, Berlin Cert runs tests until the product eventually breaks (destroying
test). They also test and certify products during the whole year, and in
none of all performed tests, an actuator failed.
The simple reason for this is because we use so called “ball spindle
driven actuators unlike the nylon nut actuators that most all other manufacturers
of mobile hoists use. Above mentioned actuators are costing more than the
ones that use spindle nuts out of plastic (Nylon or similar) materials,
but they have almost no mechanical wear.
The Actuators in hoists manufactured by Horcher Lifting Systems have no limited
lifetime, replacement of the hoist or parts of the hoist shall be determined
by a trained service technician during normal inspection terms.
