With a closed roof, the hardtop
the container offers the same
reliable protection as provided
by a standard box.
Hardtop containers have more
lashing points than other
container types. This guaran-
tees reliable and convenient
securing of cargo.
Where required, the hardtop
the roof can be stowed upright in
the container during transport,
reducing the inner width of the
box by only 13 cm (5'1/8''). A tarpaulin may replace the roof upon request from shipper.
Main features of hard top container
The hard top container is ideal for :
bulky cargo that cannot be stuffed
via the door opening
of a standard container or only just fit
through it.
Heavy goods that are best stuffed
into the container with
a crane from above or
with a large forklift.
Sensitive goods that are better stuffed
with an open roof
and top door header
into the container but
have to be optimally
protected during
transport.
Goods with excessive heights that are stuffed easier
into the container
when the roof is raised
providing an additional
7 cm (2'3/4'') of height
when loading goods.
With the roof removed and the door header
swung out, it is much easier to load cargo
using a crane via the door side.
The steel roof of most series is fitted with forklift rings to be removed using a forklift. The
weight of the steel roof is approx. 450 kg
(990 lbs).
In case cargo has overheight the roof
sections can be lashed to a sidewall inside
the container using only some 13 cm (51
/8)
of space.
If required, provide disposable
tarpaulins for the transport which can be
fastened to the walls on the outside using
lashing devices. The hardtop container provides many
lashing devices to fasten goods. The
lashing devices on the corner posts and on
the longitudinal rails of the roof and floor are
capable of bearing loads of up to 2,000 kg
(4,410 lbs) each, and those in the middle of
the side walls up to 500 kg (1,100 lbs) each.
Lashing to the side walls can only be done
after the roof has been closed.
Hard top container with special feature
Hard top container removable roof
Forklift pockets for loaded containers.
Utilizable for bulk cargo.
The roof can easily lift by hand 70 mm
(2'3
/4"), using the roof locking devices so that the door-header can be swung out
without removing the roof.
This container type has been designed
for heavy loads. While considering the
technical data (including the permissible
spread load limitations) please bear in
mind the prevalent weight restrictions for
land transport.
A container is a more stable, safer, versatile, and convenient to stuff. It features loading, unloading & improved stability with a watertight steel roof easily removed with either a crane or forklift in a few easy steps. The upper door header can also be swung out.
Alternatively, heavy cargo can be stowed much more conveniently and safely while
retaining the comprehensive protection of a standard container during transport. The hardtop container meets the technical requirements of a standard box, is available as 20' and 40' (40' also available in the high cube).
The figure below shows a hard top container with a unique feature - Hardtop containers can be loaded more conveniently from above or through the door, as
the roof can be removed with a forklift or crane. The upper door header can be swung open to
the side.
The figure shows a hard top container with a unique feature. The hardtop container has a highly effective labyrinth rubber
seal. This ensures the cargo is protected just as effectively
against rain, water, and other
environmental influences as in
a standard container.
For stuffing purposes the roof can be raised manually with the locking handles without a forklift or ladder, providing
an additional 7 cm (2'3
/4'') of
loading height.
The duty of the Terminal planner/ Central planner is to carefully plan the loading onboard to ensure minimum or no overstow of containers that will require to be re-stowed at subsequent ports.
However same must be checked on board and if found, must be brought to the notice of the Terminal planner or Local agent for their information.
Other factors should be taken into account before accepting a containership cargo stowage plan :
