Articulated Self-propelled Boom Lift Cherry Picker Solution To Slow Lifting Speed

Planning with Safety First

First of all, the articulating arm lift has fully taken care of safety issues in the detailed planning, which makes it very safe to operate and can greatly improve work efficiency. The stability of the aerial work platform also greatly shortens the working time, which is unmatched by traditional aerial work tools such as scaffolding and hanging baskets.

The color application of aerial work platforms directly affects the working conditions and psychological reactions of workers. According to the relationship between color and heart rate and breathing rate, some colors can effectively reduce the fear of people in high-altitude environments, and are not easy to cause visual fatigue. The scientific colors used in the high-altitude work platform make the workers on the high-altitude work platform reduce their sense of psychological fear.

Strict market supervision

Articulated boom lift equipment has strict production standards and quality control in the production process, which ensures that the product has never had a single safety accident due to product quality, so it has been increasingly recognized and used in large-scale projects.

Safety operation training

In order to ensure safety, there will be intermittent safety training for operators before working at heights, so as to ensure that every operator who boards the platform for working at heights has received detailed and systematic training. After the training, the qualified personnel will conduct one-on-one training, practice the machine theoretically, and then re-evaluate intermittently to see if they can work alone. Meet the requirements to get on the job.

Shandong Cathay Machinery Co., Ltd, as a professional supplier, gives the following professional suggestions for slowing down the articulated boom lift during use:

1. The lifting speed of the hydraulic lifting platform slows down, and the overflow valve is adjusted by itself. After the relief valve is adjusted, the lifting speed does not increase, but the lifting platform fails and stops working. lift

2. After the equipment is purchased and used, the speed slows down due to improper use or aging and dirt. After the speed slows down, first consider the factor of hydraulic oil flow. Factors affecting the flow of hydraulic oil include hydraulic pipelines, hydraulic valves, hydraulic oil pumps, motor speed control devices, etc.

3. The overflow valve is generally placed inside the pump station, with an adjustment valve on one side. Its function is to prevent the pressure of the hydraulic system from being too high and it is set to protect the hydraulic system. It is dangerous to simply set the relief valve. If the pressure in the oil cylinder or oil pipe is too high, serious failures such as blasting may occur. The customer of the lifting platform stopped the fault because he adjusted the overflow valve by himself.

4. The pressure of the hydraulic system should be checked only when the hydraulic lifting platform cannot start with the load. If the pressure is lower than the normal range, the setting value of the relief valve can be adjusted.

5. The hydraulic oil has deteriorated or has impurities. After the hydraulic oil has been used for a long time, there may be impurities or deterioration in the hydraulic oil. Take a sample for inspection to see if it contains solid particles, discoloration, or odor. Replace the hydraulic oil if necessary.

6. The hydraulic pipeline may be blocked. The hydraulic pipeline is also a very important link, check whether the hydraulic pipeline is smooth. Wenshao Lift reminds everyone to focus on checking whether all hydraulic valves, including one-way stop valves, electromagnetic reversing valves, proportional regulating valves, and overflow valves, are blocked or stuck. If there is a problem, the hydraulic valve should be cleaned or replaced in time.

7. The hydraulic pump is also an important factor affecting the flow of hydraulic oil. Hydraulic pumps that have been used for a long time are also prone to problems. When the speed of the hydraulic lifting platform slows down, you should check whether the oil supply flow of the hydraulic pump is stable. If any problem is found, please contact the manufacturer in time to avoid the expiration of the warranty period.

8. There may be a leak in the hydraulic system. Check whether there is leakage in the hydraulic system, focusing on checking the hydraulic pipes and joints, oil cylinders, and hydraulic valve connections. If there is hydraulic oil leakage, replace the composite pad or wrap the raw material belt.

9. The relief valve cannot be adjusted by itself.

1. Environmental characteristics of the hydraulic system of the hydraulic lift

By controlling valves and other accessories, oil is used as the working medium, and the whole set of devices that use the pressure of the oil to control the work of the hydraulic actuator is called the hydraulic system. It mainly includes five parts: power components, executive components, control components, auxiliary components (accessories), and hydraulic oil.

Based on the characteristics of each component itself, the particularity of the hydraulic system environment is determined. Its main features are:

(1) The fluid resistance of the hydraulic oil is relatively large, the leakage is serious, and the airtightness must be good;

(2) The temperature dependence is large, the temperature condition should not be too high or too low, and the temperature requirement is high;

(3) The vibration is serious, and the requirements for vibration resistance are strong.

2. Common failures of the hydraulic system

Accident failures of the hydraulic system are not uncommon, and they often occur. The reasons for the common failures of the hydraulic system of the lifting platform mainly include the following aspects:

① Leakage at the connection joint;

②Stuck valve core;

③ Block the small damping hole;

④ Missing or wrong installation of springs or seals;

⑤ Improper design;

⑥Component processing is not in place;

⑦Component aging and so on.
