What is the maximum pay load capacity of a reefer 40 High cube container?

1 x 40' RH  maximum payload in metric is 29,480KG

CMA CGM 29300 kg

Yang Ming 28560 kg

Maersk 29480 kg (Standard)

......

So as you can see, there is no only one capacity

Payload depends on the design / spec of the container. Usually, payload on a40HC reefer is between26 to30 tons and this information is found on the CSC plate of that particular container.

Operator or the owner of the container will also be able to supply payload details.

its a30mt as for my experienced and this is a subject for approval from the container operator or  shipping line agent in the port of loading.

26.380ton
