Temporarily Installed Suspended Access Equipment 

  18 

a.

 

Cleaning the surface; 

b.

 

Cleaning  the  surface  of  the  electromagnetic  brake  and  the  end  cover  of  the 
motor by removing the cover of the motor; 

c.

 

Cleaning the surface of the steel rope and clear out the rust; 

d.

 

Prevent the water and dirty matter from entering the hoist and motor. 

7.2 Daily Check 

a.

 

Reliability of the safety lock; 

b.

 

Emergency stop and limit switch; 

c.

 

Reliability of the electromagnetic brake; 

d.

 

Sensitive of the manual descending device; 

e.

 

Steel rope, rope clamp and connections; 

f.

 

Making the suspended platform move upward and downward 3-5 times with 
the travel of about 3-5 meters; 

g.

 

Following  the  “Daily  Check  Items”  (see  attached  table  2),  check  two  times 
every  day  (morning  and  afternoon).  It  is  not  allowed  to  use  the  suspended 
platform with any troubles. 

7.3 Check Periodically 

The safety lock must be re-calibrated in six month from the date of the delivery 

by the manufacturer; and the hoist must be checked by the qualified person. 
Generally, the equipment should be checked at an interval of 2 months depending on 
the  application  condition  and  the  working  period.  After  the  end  of  use  of  entire 
machine, a thorough keeping and examination should be done. 

7.3.1

 Hoist: 

a.

 

Replace the oil in the gear reducer: No. 30 machine oil, quantity: 0.6 kg; first 
replace in 20-30 days, then replace in one or two months intervals. Check the 
wear-out condition of the worm and gear. 

b.

 

Clearing out the dirty matter by removing the cover of the hoist; cleaning the 
gear  and  replace  the  grease;  check  the  wear-out  condition  of  the  bearing 
assembly, guide roller, steel ring and press pan. 

c.

 

Cleaning the electromagnetic by removing it; check the wear-out condition of 
the  armature  and  the  brake  disk.  Replace  if  the  armature  is  deformed  or  the 
thickness of the brake disk is less than 10 mm. 

7.3.2

 Safety lock: check if the arm action of the lock and the rotation of the roller are 

sensitive. 

7.3.3

 Electric control box: the isolated resistance should be less than 2M

Ω

; check the 

electric elements and the connecting wire; replace the elements, if necessary, based on 
the diagram; check the system condition with power on. 

7.3.4

 Check if the working steel rope and safety steel rope are in good condition. 

7.3.5

 Check if the suspended platform and the suspension mechanism are deformed or 

damaged; if there is any crack and fracture in welding of the structure. Repair or reject 
if necessary.
