MQ Model portal crane is a multi-function large size loading and unloading equipment for handling of chandlery. It is applicable to all kinds of big docks and ports and can move freely along the pre-set rails. This model is widely used in various fields with high operating efficiency. This Model includes single girder type and single Rack Luffing type. Facilitated with compensating pulley system, the crane is capable of horizontal movement with load and joint operation for slewing, hoisting and luffing at any angles with load. The crane has the advantage of energy saving and high efficiency. The activities conducted by this machine are stable , reliable, and safe.
This model of crane is designed and manufactured according to GB3811-83 Criterion of Designing for Cranes, , GB6067-85 Safety Rules on Cranes, GB17495-1998 Technical Requirement on Portal Crane, JT400-1999 Safety rules on Portal Crane and other related standards.

Ship Portal Crane |
|
 |
 |
| |
|
 |
| |
| |
50t-60m portal crane is designed for the setting in the
shipyard and the large manufactory.
This crane is single boom structure which ensures a
horizontal path of the load
throughout luffing and stable
slewing at any angle with load .The
hoisting, luffing and slewing
mechanisms can be operated
individually or jointly with the
advantages of large radius and high
speed.
The cab is of panoramic-view type. The high quality marine
cables and controllers are provided
in electrical system. The central
slip-ring collector has the
advantages of large capacity and
good property and is suitable for
shipyard frequent operation.
Necessary electrical and mechanical safety protection devices
are provided for all mechanisms. |
