Operator’s Manual for Crawler Crane

Chapter 3 Safety Guidelines

3.1 Operational planning

In addition to a perfectly working crane and a well-trained crew, operational planning is an important precondition for safe and reliable crane operation.

The crane operator must obtain or receive the necessary information (familiarize himself with the operating manual, basic knowledge about pneumatic, electrical and hydraulic drive, and notes for safe operation as well as operating environment) before starting the crane, in particular: a) Clearly define the area of responsibility of all personnel concerned. b) Type of crane operation and required working mode c) Distance between the lifting points and surrounding buildings d) Influence of public facilities (including the overhead high/low voltage lines and underground gas pipes). e) Space requirements at the work site f) Movement restrictions due to surroundings (e.g. is there another crane nearby in working) g) Number, material, dimensions, and weight of load(s) to be lifted h) Required lifting height and slewing radius i) Load-bearing capacity of soil or surface to be operated upon j) Height and width of thoroughfares leading to the site. k) Other factors affecting the site (e.g. weather, live lines, etc.) l) Communication means adopted between signalman and crane operator m) Take appropriate measures to keep people and equipment unconcerned away from the working area

Based on the above information, the crane operator must assemble the equipment required to operate the crane:

– Required working mode for crane operation

– Hook blocks/load hook(hook with/without pulley)

– Weight of counterweight, etc

Caution

(1) A correct and complete operational planning is vital for safe and problem-free operation of the machine. The operation planner must plan a safe and reliable operational planning by obtaining and analyzing all necessary information about the operation and considering all the factors that may impair safety of crane operation.

(2) If the crane operator does not possess all necessary and required information, it may prove impossible to carry out the intended work and accidents may be the result!
