Rtg Container Gantry Crane Portable Rubber Tyre Double Girder Crane
Rtg container crane is a type of large dockside gantry crane found
at container terminals for loading and unloading intermodal
containers from container ship.Main structures are portal frame,
power transmission system, hoisting mechanism, crane traveling
mechanism, trolley traveling mechanism and telescopic spreader.
Trolley with container spreader inside travels along girder track
to handle and stack containers.It adapts specialized spread and can
hoist different types container like 20 feet, 40 feet and 45
feet.The rubber tire container gantry crane is the special
machinery to operate at pier. It walks through rubber tire and it
can operate flexibly.

Notes:The foregoing attached table shall only be used for reference. The
actual application shall be appropriately modified according to
1. It adopts all-hydraulic driving , built-in diesel generator to
provide power, good liquidity;
2. Adopt the way that travelling mechanism is hinged to
longitudinal beam to eliminate the stress caused by uneven road
surface when walking;
3. Effective and optimization design minimize the self-weight and
ensures safety, stability and intensity.
4. All parts are highly cost effective, highly standardized, with
high accuracy, reliable quality and stable performance, also easy
to install and freely combine.
5. Be suitable for different operating conditions and provide you
Rtg Container Gantry Crane is mainly used for loading and
unloading, handling and stacking of containers at railway transit
yard and large container yard.
The port/harbour cpntainer Rtg crane:To guarantee the normal
operation of crane and avoid the personal casualty and mechanical
damage, the safety device we provide are not only the electric
protective devices or alarm bell but also other equipments as
1. Limit Switch:Safety limit switches for stoppers prevent over
traveling in all motions.
2. Anti collision device: When two crane traveling on the same
rail, the cranes will install the 3. Current weight overload
Includes automatic stopping type lifting weight limiter and weight
4. Lifting limit switch and traveling limit switch
6. Electrical protection: The main insulation switch, emergency
stop switch, short circuit, Zero voltage protection, loss of field
protection, Current overload protection, over speed protection,
zero position protection Phase sequence protection and adopted
crane specially anti- vibration contactor etc.
Parts show :
Rtg Container Gantry Crane is composed of main steel structure,
crane travelling mechanism, trolley,container spreader
and so on.
