Max date in analytic function

Question

I have records that has repeating load dates.
I would like to pick the records that has the maximum load_dates.
My source data looks like this -
( select 60589 as C_number, to_date('01/08/2012','DD/MM/YYYY') as load_dt from dual union all
select 60768, to_date('01/08/2012','DD/MM/YYYY') from dual union all
select 60888, to_date('01/08/2012','DD/MM/YYYY') from dual union all
select 12345, to_date('01/09/2012','DD/MM/YYYY') from dual union all
select 54321, to_date('01/09/2012','DD/MM/YYYY') from dual union all
select 66666, to_date('01/10/2012','DD/MM/YYYY') from dual union all
select 55555, to_date('01/10/2012','DD/MM/YYYY') from dual)
I would like to pick records with the max load_dt that means
C_number load_dt
666666 01-Oct-12
555555 01-Oct-12
I have written an oracle analytic function but it's not working the way it should be -
My query looks like this -
select a.*
from
select
c_number,
load_dt,
max(load_dt) over (partition by load_dt) as mx_dt
from table_name
where
load_dt = mx_dt;
It returns all the rows for some reason.
Any help or guidance is highly appreciated

without analytical..
with mydata as
( select 60589 as C_number, to_date('01/08/2012','DD/MM/YYYY') as load_dt from dual union all
select 60768, to_date('01/08/2012','DD/MM/YYYY') from dual union all
select 60888, to_date('01/08/2012','DD/MM/YYYY') from dual union all
select 12345, to_date('01/09/2012','DD/MM/YYYY') from dual union all
select 54321, to_date('01/09/2012','DD/MM/YYYY') from dual union all
select 66666, to_date('01/10/2012','DD/MM/YYYY') from dual union all
select 55555, to_date('01/10/2012','DD/MM/YYYY') from dual)
select *
          from mydata
          where load_dt = (select max(load_dt) from mydata);
