Both AC (Alternating Current) and DC (Direct Current) electrical motors are crucial for crane operation, providing the power needed for movements like hoisting, trolleying along the crane bridge, moving the structure of gantry cranes along the rails, or slewing the crane arm in jib cranes.
The demanding operating conditions means that motors sustain various issues. Common problems that develop over time include:
Our experts can address all these issues and more. We carry out repairs that involve specific parts and minor mechanical damage, and comprehensive overhauls that involve disassembling the motor and restoring it to tip-top condition. If a motor has suffered irreparable damage, repairs are not cost-effective, or a more efficient motor is required, we can replace the motor.
We work on any make or model of faulty or worn out drive motors, such as Siemens, ABB, Weg, Ametek, Schneider, Nidec and more.
We have clients across the UK who depend on our skilled team of engineers to diagnose, repair, monitor, overhaul, remove and refit ailing gearboxes of all types on a wide range of lifting equipment, including cycloidal, helical, spur, worm, planetary, hypoid, spiral bevel and traction drives.
We can competently and efficiently handle any common gearbox problems, like bearing failure, oil leaks, gear teeth damage, shaft bending or misalignment, keyway damage, and lubrication issues. We monitor gearbox vibration and noise which are symptomatic of underlying problems.
Our engineers will offer open and honest advice about whether gearbox malfunctions can be addressed with repair, replacement or rebuilding, assessing such factors as:
We can offer on-site support for gearbox issues and workshop facilities for gearbox disassembly, inspection, repair and testing across the UK, for gearboxes from leading brands like Kone, Beta Power, ABB, Cleveland Gear Col, Bonfiglioli, Brevini, ZF and Allison, Dana Spicer and many more.
Inverter drive units (also known as Variable Frequency Drives (VFDs) or variable speed drives) are sophisticated electronic devices that control the speed and torque of the electric motors used in lifting equipment, allowing for precise control.
Troubleshooting and repair of inverter drives requires specialised knowledge and experience – something which we at TC Motion Repairs Ltd. have plenty of, along with the equipment we need to diagnose, repair, calibrate and test these crucial drives.
If it can’t be repaired, we’ll assess your faulty inverter drive unit for possible overhaul, or removal, refitting or replacement. We’re familiar with inverter drives from most leading manufacturers including Siemens, ABB, Kone, and Vector.
We deal with any and all inverter drive faults and failures, such as:
Don’t compromise your crane’s safety, performance and service life by neglecting the well-being of the inverter. Partner with us to ensure trouble-free smooth, precise control of your cranes.
PLCs (Programmable Logic Controllers) and CPUs (Central Processing Units) constitute the brain of your crane. Like any complex electronic system they are susceptible to various issues that can lead to malfunctions, downtime and – in severe cases – dangerous accidents.
Our specialists have the knowledge and expertise to keep the PLC – that robust industrial computer that houses the crane’s control system – and it’s processing core working together seamlessly to ensure the crane operates efficiently, safely and accurately.
There is plenty that can go wrong with your crane’s PLC, with hardware failures and software glitches and programming errors at the top of the list, followed by environmental factors like temperature extremes, electrical noise and interference in the surroundings, the ever-present risk of human error and even, increasingly, cybersecurity risks.
The CPU itself can suffer internal component failure, memory chip issues, or even fall victim to problems with its precise internal clock.
A malfunctioning PLC or CPU can lead to a range of critical problems from minor glitches to complete system failure in a crane – not something any operator should risk lightly.
Call us in to diagnose, repair, overhaul, remove, refit or replace your faulty PLC and CPU controllers. Along with our meticulous workmanship you’ll get a load of free advice for peace of mind going forward.
