그만큼 트럭 탑재 크레인, also referred to as the 트럭 탑재 크레인 transporter, is classified based on the tonnage of the crane, ~와 같은 2 톤, 3.2 톤, 5 톤, 6.3 톤, 8 톤, 10 톤, 12 톤, 16 톤, 20 톤, 등. Different tonnage 트럭 탑재 크레인s come with varying configurations. 일반적으로, small-tonnage models are less likely to be equipped with outriggers, while large-tonnage 트럭 탑재 크레인s typically have both front and rear outriggers. The rear outriggers play an indispensable role in the operation of the 트럭 탑재 크레인. 그래서, what aspects need to be taken into account during the use of the 트럭 탑재 크레인, and what are the common faults that might occur?
When a 트럭 탑재 크레인 with rear outriggers is deployed on a construction site, utmost attention must be paid. It is crucial to select a flat and sturdy road surface to guarantee that the outriggers can make maximum contact with the ground and provide stable support for the lifting operation.
Let’s elaborate on this point. A stable and level ground surface is essential to evenly distribute the weight and forces exerted during the lifting process. Uneven or unstable ground can lead to instability of the crane, increasing the risk of tipping over or causing inaccurate lifts. This not only poses a threat to the safety of the operation but can also result in damage to the equipment and the load being lifted.
Attention should also be given to the correct operation sequence. Each component of the 트럭 탑재 크레인 has a specific and predefined operation sequence. 첫째로, the two-way hydraulic lock should be opened. The horizontal outriggers should then be extended to ensure they are properly positioned and fully extended. Only after this is accomplished should the vertical outriggers be operated. This sequential approach helps prevent the outriggers from hitting the ground and causing potential damage.
After the operation is completed, it is imperative to close the hydraulic lock. Failure to do so can result in the horizontal outriggers sliding out unexpectedly, which can lead to dangerous situations and potential equipment damage.
Pay close attention to any oil leakage phenomenon. Internal damage to the hydraulic control valve of the vertical outriggers of the 트럭 탑재 크레인 can lead to leakage or surface damage to the vertical outriggers. 게다가, damage to its sealing ring can also cause internal leakage. Regular and thorough inspections should be carried out to proactively prevent and troubleshoot such issues.
The common faults of the rear outriggers of the 트럭 탑재 크레인 include the following:
- When retracting the vertical outriggers, the horizontal outriggers are also retracted simultaneously.
The reason for this issue lies in a malfunction of the horizontal outrigger overflow valve of the multi-way valve on the lower part of the vehicle.
The solution involves removing any clogged impurities and promptly replacing any damaged components. It is essential to ensure that the overflow valve functions smoothly and without obstruction to maintain the proper operation of the outriggers.
- One of the outriggers extends very slowly.
This could potentially be attributed to either a loose positioning of the multi-way valve, which subsequently loses control over the speed of this particular outrigger, or there might be internal leakage within the horizontal cylinder. Internal leakage leads to insufficient pressure, thereby resulting in a slower extension speed.
The solution here is to firmly fasten the positioning of the multi-way valve. 추가적으로, interchange the vertical and horizontal oil pipes to observe if the horizontal outrigger is still slow. By eliminating the normal components, inspect the cylinder to confirm if there is any internal leakage. If so, replace the seal or the entire cylinder as necessary.
- The rear outriggers extend and retract slowly and have low pressure.
The cause of this problem is often internal component damage within the overflow valve of the multi-way valve, which leads to internal leakage.
The solution involves conducting a detailed check to confirm whether the fault lies with the overflow valve or the pump. The specific operation is as follows: Disconnect the pipe connecting the overflow valve of the multi-way valve to the hydraulic oil tank. Position the outrigger selection handle in the neutral position and operate the reversing handle. Observe the pressure gauge. If the pressure does not increase, check whether there is oil flowing out of the disconnected oil port of the multi-way valve. The presence of oil indicates internal leakage of the overflow valve or that the pressure value is set too low. The absence of oil indicates damage to the oil pump.
The outriggers of the 트럭 탑재 크레인 are directly related to the safety of the operators. Everyone must exercise extreme caution and vigilance during operation.
A minor oversight or failure to address these faults promptly can have severe consequences, including equipment damage, property loss, and most importantly, threat to human life. Regular maintenance, proper operation, and immediate attention to any anomalies are crucial to ensure the safe and efficient functioning of the 트럭 탑재 크레인‘s outriggers.
결론적으로, understanding the common faults and their solutions, along with adhering to correct operating procedures and maintenance schedules, is vital for the reliable and safe operation of the rear outriggers of the 트럭 탑재 크레인.
