Corrective maintenance and retrofits

Corrective maintenance is carried out after a fault is detected. It aims to restore 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.

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 modernisations, retrofits typically require much less planning and downtime.

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. We will coordinate crane and hoist repairs around your production schedule in order to minimise downtime.

In the event of a breakdown, contact us for emergency repairs.

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.

Crane component replacement

In addition to hoists, there are numerous other components that can be replaced or retrofitted:

• Travelling machinery, end carriages, 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

Control upgrades

There are a variety of retrofits that can improve the way your crane is powered and controlled.

Load control: Stepless speed controls, collision avoidance systems and other technologies can often be added or upgraded to bring current technologies into use.

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.

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

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 is designed to automatically limit load swing by controlling the bridge and trolley acceleration and deceleration rates.

Shock Load Prevention allows for smooth load control. If an attempt is made to pick up a load too abruptly, hoisting speed is automatically and immediately adjusted.

Protected Areas are no-go areas, which the crane operator cannot override or adjust.

LED lighting retrofit for cranes

Traditional metal-halide or halogen lights have a short service life and can suffer damage due to vibrations, resulting in increased costs and less efficient operations. An LED Lighting Retrofit will provide you with lights that have a much longer service life and are far less prone to damage from vibration.

Traditional lighting can account for 50 to 90 per cent of the electricity used by a crane. Lighting is, therefore, a major cost in all crane operations. LED lights provide the same amount of lighting to the working area as standard lights, yet they consume little more than one third of the energy.

Get connected to your crane fleet

A remote service connection can be retrofitted to your existing overhead cranes to give you access to TRUCONNECT® Remote Services. This retrofit enables you to receive detailed information about your cranes on the device of your choice. TRUCONNECT analyses compiles your fleet data and turns it into valuable information so you can monitor your cranes using the latest technology.
