DESCRIPTION:
Krupp Crane KMK 7250 Operating Instructions Manual 2085930 – PDF DOWNLOAD
Foreword:
- These operating instructions with lifting capacity tables and outrigger pressure tables belong to the
scope of supplies of truck crane KMK 7250. They are intended first and foremost for the crane operator
and contain all information required to operate truck crane KMK 7250 safely for the permitted applications,
which are listed. - These operating instructions are not intended to be used as a training manual for trainee crane operators.
The descriptions given have been written on the assumption that they will be read by crane operators
who are fully trained for working with truck cranes. - Plan each job carefully. Make sure that you obtain all the information you need concerning the route to
the site (distance, route to be followed, headroom, maximum loads permitted to cross bridges, etc.).
Find out details of the work to be performed by the crane (load bearing capacity of the ground, weight
and dimensions of the loads to be lifted, required lifting heights and working radius, and buildings, etc.,
which will restrict movement). Assemble the equipment which will be needed (lifting tackle, counterweight,
packing material for the outriggers, etc.). Organize the journey and procure any permits
needed for it. - If you do not plan things properly you will be forced to improvise – and improvisation often
leads to accidents!
A word of advice to all crane operators: - As you know, as the crane operator you are responsible for the crane and for all work connected with it.
For the safety of those around you – and of course your own safety – please follow the advice given
below: - Before you use the crane for the first time, familiarize yourself with its operation in all permitted operating
modes. Read these oper~ting instructio_ns through and compare all of the illustrations with your
crane. Go through the· described procedu·res step· by step· with your crane.
