7.1.1 

Free-wheeling of chain 

When  the  unit  is  used  appropriately,  unintended  activation  of  the  free-wheeling  mechanism  under  load  is 
impossible. Opening of the brake system with only small load is possible, this is no mistake.  

   DANGER! 

Never activate the free-wheeling mechanism if the hoist is under charge. 

 

Switching ON the free-wheeling mechanism 

 

  Place the switch knob in middle position. 

 

Illustration 10   

 

 

  Pull the free-wheeling wheel upwards in 

direction ▲ . 

 

  The  chain  can  be  pulled  through  in  both 

directions. 

 

A free-wheeling OFF 

B free-wheeling switched ON 

 

Illustration 11   

 

Switching OFF the free-wheeling mechanism 

 

 

  Turn the free-wheeling wheel with one hand in 

direction ◄ and pull the load chain at the same 
time.  

  Free-wheeling wheel turns back to position 

OFF. 

  Free-wheeling mechanism is switched OFF 

 

C Switch OFF the free-wheeling. 

D free-wheeling OFF 

 

Illustration 12   

 

 

NOTICE!

 

When free-wheeling is activated and chain is pulled through the divice, an increasind resistance 
must be there with increased speed. This is no mistake . 

 

7.2 

Brake and pawl 

The brake system needs a minimum load of 3% of the capacity. 

Only  this  minimum  load  makes  sure  that  the  load-pressure-brake  closes  correctly.  When  the  brake  closes 
correctly, the load is safely held. 

 

   DANGER! 

Working situations with no guarantee that the minimum load is charged, are forbidden! 

 

The brake remains closed (stuck) if: 

  The ratchet lever hoist is uncharged without lowering the load, i.e. in case of vertical lifting/lowering or in 

case of horizontal pulling/tensioning. 

  The load hook is pulled against the housing and got stuck there. 

The chain does not move, the load cannot be lowered. 

Remedy: 

  Charge the ratchet lever hoist again
