Overhead crane corrective maintenance is carried out after a fault is detected and is aimed at restoring your crane to a condition in which it can perform its intended function. Timely repair of known faults reduces the likelihood of emergency breakdowns and is often mandated by regulation.

CORRECTIVE
MAINTENANCE
Corrective maintenance is carried out
after a fault is detected and is aimed
at restoring your crane to a condition
in which it can perform its intended
function. Timely repair of known
faults reduces the likelihood of
emergency breakdowns and is often
mandated by regulation.

3. PLANNED
CRANE REPAIRS
Correcting known faults is good for
safety and makes economic sense.
Component faults identified during
inspections and preventive maintenance
are documented, and corrective actions
are discussed with you.
In the event of a breakdown, contact us for emergency repairs.
COORDINATED TO YOUR SCHEDULE

4. COORDINATED
TO YOUR
SCHEDULE
Planned repairs are scheduled according
to inspection and maintenance reports.
Optimally the repair is coordinated and
scheduled around your production
schedules. Our technicians are equipped
to perform a wide scope of planned
repairs that include repairing, adjusting,
and replacing any component or
equipment part.
PREAUTHORIZED REPAIRS
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

5. PREAUTHORIZED
REPAIRS
Preauthorized repairs provide a blanket
authorization to perform corrective
maintenance, up to a certain amount, in
order to get small repairs or adjustments
arranged and completed quickly and
efficiently. They are normally completed
during inspection or preventive
maintenance visits.

6. RETROFITS
Retrofits are a relatively easy
and economical way to add
current features and
technologies to your existing
overhead crane. Common
retrofits include hoist and
component replacements,
variable speed control, radio
remote control and LED
lighting. Compared to
modernizations, retrofits
typically require much less
pre-planning and downtime.

HOIST
REPLACEMENT
Has your hoist reached the end of its
productive design life? No matter how
well maintained, your hoist will not
last forever.
Konecranes CXT® hoists can be
retrofitted onto most cranes. Our pre-
engineered hoist retrofits are designed
for easy installation, causing minimal
disturbance to your production.
IMPROVED LOAD HANDLING
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

8. IMPROVED
LOAD HANDLING
The CXT hoist has many features that ease
load handling and maintenance. With
Adaptive Speed Range (ASR), the motor
speed varies according to the load. This
allows for optimal speed and enhanced
safety when handling heavier loads. Its
service-friendly reeving design provides
improved access to the upper rope sheaves
and overload device, making rope changes,
rope length adjustments and sheave
replacements fast and easy.
MOTOR AND BRAKE EASILY ACCESSIBLE

9. MOTOR AND BRAKE
EASILY ACCESSIBLE
The CXT hoist motor brakes are sealed and dust-
proof. Built for low maintenance and trouble-free
operation, CXT brakes are designed to require
minimal adjustment and built to last numerous
operating cycles.
The unique placement of the motor inside the drum
protects the motor from contaminants, while
increasing the cooling ability. The design makes
the motor and brake easily accessible for
maintenance.

10. ELECTRIC
CHAIN HOIST
REPLACEMENT
Konecranes chain hoists are
designed for flexibility and durability
in industrial applications.
You can use the electric chain hoists
at a workstation, on an overhead
travelling crane or with a jib crane.
Konecranes CLX chain hoists are
ideal replacement hoists for all
these applications.
FLEXIBILITY AND EASY ACCESS
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

11. FLEXIBILITY AND
EASY ACCESS
You can move the electric chain hoists around
your workshop and put them to different uses.
Compact headroom, hook suspension, push
trolley, motorized trolley and many other options
give you the flexibility you need.
With CLX, the hoist motor is easy to access,
maintain and replace. The same easy
serviceability applies to the chain drive, slip
clutch, hoist limit switches, electrics and gears.
DURABLE LIMIT SWITCHES AND BRAKES

12. DURABLE LIMIT
SWITCHES AND
BRAKES
The standard upper and lower limit switches
of Konecranes hoists are durable. Protected
against environmental influences, they bring
improved safety and performance to the
hoist and the user.
The brake is a critical part of the chain hoist
and the safety of your lifting equipment. Our
self-adjusting brake is designed to last the
complete lifetime of the hoist.

13. CRANE COMPONENT
REPLACEMENT
In addition to hoists, there are numerous other
components that can be replaced or retrofitted:
• Travelling machinery, end trucks,
wheels, drives, etc.
• Ladders, platforms and other
means of crane access
• Safety apparatus such as tie-off
lines and limit switches
• Drive and hoist motors

14. CONTROL
UPGRADES
There are a variety of retrofits
that can improve the way your
crane is powered and controlled.
LOAD CONTROL
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

15. LOAD
CONTROL
Stepless speed controls,
collision avoidance systems and
other technologies can often be
added or upgraded to bring
current technologies into use.
RADIOS
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

16. RADIOS
Pendant controls require the operator to
move with the crane. With radio controls,
the operator can stand in a position that
gives them a better view of the load.
Improved user ergonomics reduces the
strain for the operator and can
simultaneously increase your productivity.
Radios for all crane brands as well as
licensed frequency and radios with
special features are available.
CONDUCTOR SYSTEMS

SYSTEMS
Konecranes offers conductor
systems, including festoons,
energy chain and conductor bar
systems to improve safety and
reduce operating costs.

18. SMART
FEATURES
A host of Smart Features can
be added to your overhead
crane to give you more
control over material handling
in your production process.
SWAY CONTROL

19. SWAY
CONTROL
Sway Control limits load swing by
controlling bridge and trolley acceleration
and deceleration. This allows for faster
load handling and more precise positioning.
TARGET POSITIONING

20. TARGET
POSITIONING
Allows an operator, with the single push
of a button, to lift a load to a
predetermined height, move it to a
programmed location and place it.
PROTECTED AREAS

21. PROTECTED
AREAS
Limit crane movement to a designated working
area. This maximizes the safe operating space of
the crane, while helping to reduce the risk of
accidents, equipment collisions and load damage.

22. LED
LIGHTING
Traditional metal-halide or
halogen lights have a short
service life and can suffer from
damage due to vibrations,
resulting in increased costs
and less-efficient operations.
With an LED Lighting Retrofit
you get lights that have a much
longer service life, and your
lights will be far less prone to
damage from vibration.
USES LESS ENERGY
CORRECTIVE MAINTENANCE RETROFITS HOISTS COMPONENTS CONTROLS SMART FEATURES CONTACTTRUCONNECTLIGHTING

23. USES LESS
ENERGY
Traditional lighting can account for 50 to
90 percent of electricity used by a crane.
Lighting is, therefore, a major cost in all
crane operations. LED lights provide the
same degree of lighting to the working
area than standard lights, yet consume
little more than one third of the energy.

24. TRUCONNECT
A remote service connection can
be installed as a retrofit kit for
your existing industrial cranes to
give you access to TRUCONNECT
Remote Service.
TRUCONNECT is a suite of
remote service products and
applications to support
maintenance operations and
drive improvements in safety
and productivity.
REMOTE MONITORING

25. REMOTE
MONITORING
TRUCONNECT Remote Monitoring
uses sensors to collect data, such as
running time, motor starts, work cycles
and emergency stops, providing visibility
to crane usage. It also provides brake
and inverter monitoring. The data is
transmitted to the Remote Data
Center, where it is compiled and made
available on the yourKONECRANES.com
customer portal.
