ဟိ ထရပ်ကားတပ်ဆင်ထားသောကရိန်းis a type of vehicle commonly utilized in engineering construction. Regrettably, within engineering construction incidents, a considerable number of accidents are triggered by the rupture of wire ropes. အမှန်တိုင်းပြောရရင်, many of these accidents could have been evaded initially. This demands that we exercise greater caution during normal operations and not overlook the wire rope when conducting maintenance on theထရပ်ကားတပ်ဆင်ထားသောကရိန်း.
ပထမဦးစွာ, let’s delve into the reasons behind wire rope breakage. The summary is as follows:
When lifting goods, if the hook lands on the ground and the wire rope pops out of the groove and slips into the side seam, a phenomenon known as rope jumping occurs. When the crane exerts force, the wire rope gets jammed and subsequently breaks. This situation often arises due to improper operation or insufficient attention during the lifting process.
Overloading poses a significant risk. When lifting goods that exceed the weight limit, the wire rope is subjected to a load beyond its capacity to withstand. This excessive stress can lead to its failure and poses a serious threat to safety.
Regular maintenance is of paramount importance. Frequent application of butter to wipe the wire rope in a timely manner helps reduce friction. Neglecting this aspect can accelerate the wear and tear of the wire rope, increasing the likelihood of damage and breakage.
It is imperative to be vigilant for any signs of fraying on the wire rope. Once such indications are detected, immediate replacement must be carried out without delay. Remember, safety should always be the top priority!
ကဲ, let’s explore the key points to note during the maintenance of the truck-mounted crane:
Pay meticulous attention to the presence of aging, leakage in pipelines, valves, and oil seals. ထို့ အပြင်, regular checks of the hydraulic oil are essential, encompassing aspects such as the oil level, the presence of dirt, and viscosity. Ensuring the integrity and proper functioning of these components is crucial for the smooth operation of the crane’s hydraulic system.
Keep a watchful eye on any leakage in the control valve. This includes observing whether the outriggers retract or extend automatically, and whether the boom drops unexpectedly after the luffing cylinder lifts it. Such malfunctions can indicate potential issues within the control system and require prompt attention.
Be attentive to any abnormal noises emanating from components such as the power take-off, oil pump, slewing ယန္တရား, and winch. Unusual sounds can be an early indicator of mechanical problems or excessive wear and tear, warranting further inspection and maintenance.
Ensure proper lubrication at crucial points like the slewing bearing and the fulcrum of the hydraulic cylinder. Adequate lubrication reduces friction, extends the lifespan of these components, and helps maintain the smooth operation of the crane.
Make a point to carefully inspect the wire rope for broken wires and fraying. Also, examine the edge of the pulley for damage, assess whether the groove of the pulley is overly deep, and check if the hook structure shows excessive wear. Any of these issues can compromise the safety and performance of the lifting mechanism.
In the special vehicle market, the sales volume ofထရပ်ကားတပ်ဆင်ထားသောကရိန်းs remains highly satisfactory. The tonnage options forထရပ်ကားတပ်ဆင်ထားသောကရိန်းs are diverse. Generally, the smaller tonnages include 2 တန်, 4 တန်, နှင့် 5 တန်, while the larger ones range from 16 တန်, 20 တန်, ရန် 25 tons and beyond. The appeal of truck-mounted cranes lies in their dual functionality of lifting and transporting goods simultaneously. This versatility is what earns the trust of the majority of users and makes them a preferred choice in various construction and logistics applications.
နိဂုံးချုပ်အားဖြင့်, proper maintenance of the wire rope and other critical components of the ထရပ်ကားတပ်ဆင်ထားသောကရိန်းis not only essential for ensuring its efficient operation but also for safeguarding the safety of personnel and equipment on the job site. By adhering to regular inspection and maintenance procedures and promptly addressing any identified issues, the reliability and longevity of theထရပ်ကားတပ်ဆင်ထားသောကရိန်းcan be significantly enhanced, contributing to successful project completion and minimizing the risk of accidents.
