MAINTENANCE CHECK LIST 

 
The 

Mat Mover

® 

is designed to operate for many years without any significant service 

performed.  Depending upon the usage of the unit, it is recommended that at least an 
annual inspection is made, at which time the following steps should be taken: 
 

1.  GENERAL 
 

Make certain the Porter key switch was not substituted, and is located within full view 
(but not beneath) the 

Mat Mover

®

.

 

Check the walls in close proximity to the 

Mat Mover

®

 

for any type of protrusions that may interfere with the raising or lowering of the unit 
(i.e., new scoreboard, chinning bars, etc.). 
 

2.  LOAD BAR

 

 
Check the two (2) flange connections for any type of separation.  Tighten or replace 
bolts as required, using a Grade 5 or better bolt.  Inspect all hooks for fatigue and 
alignment.  If hooks are bent or missing, they must be replaced. 
 
The most critical connection to be inspected is the cable attachment at the load bar (or 
pulley).  These connections must be made with Grade 8 bolts and nylock nuts (a lock 
nut may be substituted). 
 

3.  PULLEY AT LOAD BAR 

(If Applicable) 

 
It is advisable to disassemble the pulley, check the sheave bearing and shaft for 
excessive wear, and replace with a factory-replacement pulley, if necessary.  There is 
a grease fitting on the sheave.  Use a standard high-temperature wheel-bearing 
grease for the sheave. 
 

4.  INSPECT HOISTING CABLE

 

 
Check cable for kinking and fraying.  The best method is to take an oily or grease-filled 
rag and rub along the cable.  The rag may hit broken strands of cable and snag.  If the 
snags appear approximately ten times in a ten (10) foot length of cable, the cable 
should be replaced.  This procedure not only checks the cable, but lubricates it for 
longer wear. 
 

5.  HOISTING WINCHES

 

 
Remove the covers on each hoist frame.  Grease the shaft bearing with a minimum 
amount of grease.  Run the units and visually inspect the drum for concentricity.  If the 
drum rotates with a cam effect (wobble), consult the factory.
