Rack Handling Safety: 
 

The racks must be assembled and installed only by skilled 
personnel having the necessary knowhow and experience. 

☞ 

See section “

Qualified Personnel

” 

 

Always wear suitable safety helmet, goggles, protective gloves, and 
safety shoes when lifting rack out of its packing and handling it. 

 

A second person should be called in or a crane be used, if the weight exceeds 20 lb.  A 
second person should also be used if the rack length exceeds 1,000 mm, in order to prevent 
injury due to bad posture.  The crane must always be operated by a crane driver.  The rack 
to be carried must be properly secured and, if necessary, the ends of the rack marked in a 
clearly visible way. 
 

 

The table below shows the weight of the individual racks. The lengths are rounded 
to the nearest round length.

When pivoting with a rack in hand, mark the pivoting radius with 
a warning sign and warning tape.  This area must be blocked 

during transport and handling so that no person may be endangered. 

 

Before starting transport of racks, make sure that the travel path is 
clean & clear, with ample room to maneuver with good footing. 

 

Avoid twisting and bending while lifting or moving.  Lift the racks 
comfortably and smoothly, keeping them close to the body. 

 

Before starting transportation of racks, it must be ascertained that 
the overall dimensions of the rack permit safe handling.  Never allow 

the load to obstruct your view!
