T27978 50-Ton Hydraulic Press (Mfd. 12/16)

-3-

3.  Attach  hydraulic  reservoir  assembly  to  out-

side of press frame (see 

Figure 5) by thread-

ing  (4)  M10-1.5  x  30  hex  bolts,  10mm  flat 
washers,  and  10mm  lock  washers  through 
frame  mounting  bracket  into  threaded  holes 
of hydraulic assembly.

4.  Attach  winch  to  outside  of  press  frame,  as 

shown  in 

Figure 6,  using  (2)  M10-1.5  x  25 

hex  bolts,  10mm  flat  washers,  and  M10-1.5 
hex nuts.

Anchoring to Floor

Anchoring machinery to the floor prevents tipping 
or  shifting  and  reduces  vibration  that  may  occur 
during operation, resulting in a machine that runs 
slightly quieter and feels more solid.

If the machine will be installed in a commercial or 
workplace setting, local codes may require that it 
be anchored to the floor.

If  not  required  by  any  local  codes,  fastening  the 
machine  to  the  floor  is  an  optional  step.  If  you 
choose not to do this with your machine, we rec-
ommend placing it on machine mounts, as these 
provide an easy method for leveling and they have 
vibration-absorbing pads.

Lag  shield  anchors  with  lag  screws  (see  below) 
are a popular way to anchor machinery to a con-
crete floor, because the anchors sit flush with the 
floor surface, making it easy to unbolt and move 
the  machine  later,  if  needed.  However,  anytime 
local codes apply, you MUST follow the anchoring 
methodology specified by the code.
