-20°C/+40°C 

 

 

) * At an atmospheric pressure range from 0.8bar to 1.1bar and an oxygen content of approx. 21% 

 

) ** Devices of this category have been specially modified and labeled by the manufacturer

 

 

 

   

DANGER!

 

The ambient temperature range must not be exceeded!

2.5 

Basic safety measures 

  Observe installation-, operation and maintenance instruction. 

  Take notice of caution notes at units and in the manual 

  Observe safety distances. 

  Take care for a free view on the load. 

  Only use the hoists appropriately. 

  The equipment is to be used exclusively for movement of goods. Under no circumstances my persons be 

moved. 

  Never load the devices beyond their working load limit. 

  Pay attention to the accident prevention regulations (UVV). 

  Should the hoist be used outside of Germany, please pay attention to the national regulations that apply. 

  Supporting structures and load-attached devices used in conjunction with this equipment must provide an 

adequate safety factor to handle the rated load plus the weight of the equipment. In case of doubt, consult 
a structural engineer. 

  If the equipment has not been used for a period of time, carry out visual checks of all main components 

such  as  chains,  load  hooks  etc.  and  replace  any  damaged  parts  with  new,  original  spare  parts  before 
putting the equipment back into operation! 

  Do not use a hoist that is defective, pay attention to any abnormal noise it makes during operation. 

  Stop working immediately in case of disturbances and remedy failures. 

  Any damage and faults must be reported to a responsible supervisor immediately. 

  If the unit is put into motion, any persons in the immediate vicinity must be informed by calling to them! 

  Please pay attention to the regulations for load carrying devices UVV for both positive and non-positive 

methods of attaching loads.
