5.1.
When is the right time to thoroughly inspect your Spierings crane?
When your Spierings crane is used in the course of the years, parts wear out and malfunctions and/or
defects occur more frequently. The average service life of the crane depends on crane type, use of the
crane, history and maintenance approx. 15 to 20 years based on maximum 8 operating hours per day,
five days a week. When do you need to thoroughly inspect your crane?
-
If several crane functions such as erecting and/or folding are slow and inaccurate or
frequent malfunctions occur;
-
If you do not fully know the crane’s history, for instance if the crane is a second hand crane
and commercially purchased with an incomplete Crane’s Logbook;
-
If the crane is older than 15 years, the crane has made many operating hours and is daily
erected and folded;
-
If the crane is used intensively and/or a lot is overloaded;
-
If you receive complaints about oil leakage, cracks or excessive noise;
-
If the annual inspections are not carried out.
What does thoroughly inspected mean?
The thorough inspection means that all the construction parts of the crane and truck, which are part of
the crane function of the machine, are inspected accurately. It may be necessary to disassemble some
parts of the crane and drive components. These may include ty bars, toothed wheels and bearings in
reduction gear units and seals in cylinders.
The inspection determines whether the service life can be extended or replacements of parts is
necessary.
5.1.1.
Electronic component
The crane control is the brain of the crane. It controls the machine and all electronic and hydraulic
systems from the moment you start up the crane. This also includes the operation and switches.
The control and the components before and after the input and output signals of the controller have at
normal use and proper maintenance a service life of approx. 20 years.
5.1.2.
Drive component of the crane
The engine and hydraulic pumps, called power pack, is the beating heart of the crane. The power pack
provides all crane functions, which include erecting, hoisting, slewing, trolley travelling and folding.
Due to wear its service life at normal use and proper maintenance is approx. 15 to 20 years.
