1. How to prevent overload the
wire rope lifting cranes

2. Lifting crane wire rope to prevent
overload measures
• Lifting crane wire rope to prevent overload measures: mounted on a crane load indicator , or
overload limiter, or alarm, eliminate overload. Strict compliance with safety procedures , to
eliminate artificial overload phenomenon . Improve the performance of the crane to reduce
frictional resistance can be adjusted via a pulley groove shape and add oil to reduce more.
• To prevent overloading the rope should take the following measures:
• 1 ) the correct selection of the safety factor , and strive to reduce the impact of load other than the
static load on the rope . Such as bending loads can increase the diameter of the pulley and the
drum to reduce the dynamic load by raising the level of the crane driver's operation , to improve
the performance of the overhead crane to reduce the frictional resistance can be reduced by
adjusting the shape of the pulley and the supplementary oil groove so .
• 2 ) strict compliance with safety rules, eliminate human overload phenomenon .
• 3 ) mounted on the electric hoist single girder gantry cranes load indicator or an overload limiter, or
alarm, to eliminate overload.
• In addition to the basic type of injury above the rope , there are high temperatures and other
factors also make rope radiation damage . But, in general , the rope is usually a regular injury , the
key is how to further our understanding of these laws, in order to identify effective prevention
methods , try to extend the life of the rope .

3. Hydraulic cranes hoist remediation
work
• Electric hoist hydraulic cranes remediation work is mainly three-
pronged approach:
• First, the Task Force has organized experts, managers, maintenance
managers and hydraulic cranes, the fault type of hydraulic jib
cranes, the fault causes were analyzed and classified, write
technical documents have practical value for the ship management
personnel implemented and in use continue to improve;
• Second, actively implement proactive maintenance by improving
training of management personnel expertise, fault diagnosis and
repair skills to improve maintenance management-level
management personnel, electric hoist for sale and;
• Thirdly, it is 70% and for oil cleanliness issues related to failure of
the hydraulic system, hydraulic system cleanliness strictly controlled
to keep it within the allowable range.
