Core segmented user demands include plug-and-play original equipment replacement, constant hydraulic oil temperature stabilization, stable motor linkage startup, impurity-free hydraulic oil circulation and unified electrical signal linkage, aiming to solve traveling block jitter, hydraulic system overheating, electric control loop trip, oil return pipeline impurity blockage and motor seat vibration offset frequent onsite electromechanical composite faults.

1.2 Pre-positioned On-site Lifting Working Pain Points Solved

• Universal aftermarket traveling block assemblies produce wheel shaft deflection exceeding 0.42mm under 260kN rated lifting load, leading to unilateral rope abrasion and uneven load bearing of FY50 drawworks steel wire rope

• Ordinary hydraulic cooling and temperature control components fail constant temperature regulation, making ZKYZ-630II hydraulic oil temperature exceed 68℃ after 580 continuous lifting hours, triggering hydraulic valve spool clamping failure

• Generic low-voltage contactors and relay parts generate signal delay under site electromagnetic interference, causing asynchronous action of BY201 oil cylinder motor startup and shutdown

• Common oil return filters have low impurity interception precision, leading to metal abrasive particle entering hydraulic valve cavity and accelerating ZKYZ-630II valve assembly inner component wear
