How often should the first-level maintenance of a crane be performed?
2 Answers
Crane first-level maintenance should be performed every 6 months. Here is some extended information about cranes: 1. Introduction: A crane refers to a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It is also called an overhead crane, aerial crane, or hoist. 2. Main characteristics of a tire crane: Its driving cab and lifting control cab are combined into one. It evolved from a crawler crane (crawler hoist), with the crawler and walking frame parts of the traveling mechanism replaced by a tire chassis, overcoming the disadvantage of crawler cranes (crawler hoists) damaging road surfaces with their crawler plates. It belongs to the category of material handling machinery.
As someone who frequently operates cranes, I believe that first-level maintenance must be adhered to daily. Before starting work each day, I spend about ten minutes checking the hydraulic oil level, testing the brakes, and inspecting the wire ropes for any wear to ensure everything is in order. If screws become loose or oil leaks, minor issues can escalate into major problems, potentially causing work stoppages or safety hazards. In practice, our team has a rule to perform maintenance after each shift, such as checking every 8 hours of operation. Getting used to this routine extends the equipment's lifespan and provides peace of mind during work. Last time, a colleague failed to lubricate the chain in time, resulting in a stuck crane boom that delayed the project—a lesson learned the hard way. In short, first-level maintenance should never be skipped; daily diligence can prevent major repair costs.
