LOAD LIMITERS

RM2M - 150 rue des Sources - 69280 MARCY L’ETOILE

Utility

The  

load  

limiter  

has  

been  

developed  

to  

prevent  

possible  

overloads  

that  

could  

appear

on  

lifting  

devices  

such  

as  

hoists,  

overhead  

cranes,  

cranes,  

hoists  

...  

It  

avoids  

cable

breaks,  

structural  

deformations  

and  

by  

way  

of  

consequently,  

accidents  

resulting  

from

problems due to overloads.

Security

Directive  

89/392  

EEC  

requires  

all  

cranes  

to  

be  

equipped  

with  

a  

load  

limiter.  

Also,

regarding   

the   

prevention   

of   

work-related   

risks,   

the   

legislation,   

Directive   

98   

/

1084CEE,  

indicates  

that  

it  

is  

necessary  

to  

eliminate  

any  

danger  

and  

therefore  

any

risk of accident. Are concerned: hoists, overhead cranes, etc…

Information

In  

the  

event  

of  

an  

accident  

following  

an  

overload,  

any  

user  

of  

a  

lifting  

device  

is

responsible  

for  

any  

accident  

resulting  

from  

improper  

use  

of  

his  

machine  

and  

in

particular,  

take  

care  

not  

to  

create  

an  

overload  

condition  

of  

his  

machine.  

In  

the  

event

of   

an   

accident,   

and   

if   

the   

machine   

is   

not   

equipped   

with   

a   

means   

to   

avoid

overloading,    

all    

site    

managers    

and    

possibly    

maintenance    

managers    

are

consequently  

responsible  

for  

any  

accident  

that  

may  

occur  

on  

the  

site.  

which  

they

are responsible for.

Verification

The   

traveling   

cranes   

must   

undergo   

annual   

periodic   

general   

inspections,   

with

reference  

to  

articles  

R.4323-23  

and  

R.4323-27

  

(

in  

french

)  

of  

the  

Labor  

Code,  

as  

well

as  

to  

the  

decree  

of  

1  

March  

2004  

adopted  

in  

these  

items.  

This  

check  

shall  

include,

inter  

alia:  

the  

operation  

of  

the  

devices  

limiting  

the  

movements  

of  

the  

hoist  

and  

the

load (top and bottom limit switches and load limiting systems)

Among  

the  

safety  

devices  

of  

traveling  

cranes,  

the  

load  

limiter  

is  

one  

of  

the  

most  

important.  

Its

installation can avoid a lot of serious accidents. It is obligatory from 1000 kg.

3  

types  

:  

electromechanical,  

power  

controllers  

and  

electronics.  

If  

the  

first  

2  

types  

are

autonomous,  

the  

third  

is  

more  

sophisticated  

as  

a  

whole  

because  

it  

is  

usually  

accompanied  

by  

a

precise  

strain  

gauge  

sensor  

and  

sometimes  

a  

load  

display  

allowing  

the  

operator  

to  

constantly  

monitor

the evolution the weight of the load, the workshop or his office.
