KUKA KR 360 FORTEC Inspection and Maintenance Guide

A2 abnormal noise, sinking or vibration: Check the balance system bearings, pressure, mechanical limit and connecting rod fixation.

Wrist abnormal noise or positioning drift: Check the axial clearance of the transmission shaft and replace it if it exceeds 0.8 mm; Check the teeth and O-ring.

Gear oil leakage: Check O-ring A4/A5, magnetic plug, oil pipe, oil pan nut, and gearbox seal.

Motor overheating: Check the load, duty cycle, ambient temperature, cooling, brake and motor current.

Cable wear or interference: Check the cable group, bending radius, shielding, separate laying, and lubrication.

Zero point loss: Mastering A1 to A6 again.

Abnormal braking: Conduct a braking test to check the parameters of the brake, motor, and controller.

Automatic mode cannot start: check safety door, operate safety signal, external emergency stop, confirm button, and mode selection.

After maintenance, functional testing must be conducted to ensure that all safety functions are effective. The replaced components must use original parts or equivalent approved parts. Screws with a rating of 10.9 or above or certified by testing can only be tightened once to the rated torque, and must be replaced after loosening. Tighten the torque according to the appendix, and follow the marked values for special positions.

Key points of standards and compliance

KR 360 FORTEC is involved in the Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, Pressure Equipment Directive 2014/68/EU, and EN ISO 10218-1、EN ISO 12100、EN ISO 13849-1/-2、EN ISO 13850、ANSI/RIA R15.6  Waiting for standards. The F variant has higher dust, lubricant, coolant, and water vapor resistance, and adopts a special paint surface and transparent protective coating. If used for other environmental conditions, KUKA Deutschland GmbH must be consulted. The balance system contains nitrogen and hydraulic oil, and must be depressurized before disposal. Only pressure free balance systems are allowed to be scrapped.

Overall, the reliability of KUKA KR 360 FORTEC depends on the installation foundation, balance system, gear oil, transmission shaft, and safety circuit. Regularly checking pressure, oil level, clearance, and torque can detect abnormalities in the early stages of faults. When encountering abnormal pressure, abnormal noise, leakage or shutdown, first lock it safely, and then investigate according to the levels of power supply, safety circuit, balance system, transmission shaft, gear oil and motor. This can reduce unplanned downtime and maintain stable operation of heavy-duty robots under harsh working conditions.
