Safety Maintenance of Aerial Work Trucks

The majority of aerial vehicle owners pay special attention to the surface and interiors of aerial vehicles when they regularly maintain aerial vehicles. After all, they are places they often see. However, some key parts of aerial vehicles require a long time to use. Will be replaced once or not often replaced, so these usually do not pay too much attention to the parts will be ignored, in fact, these parts is where the aerial vehicle owners should pay attention.

First, check the brake fluid level regularly

The condition that occurs: If the brake fluid is insufficient to allow air to enter, the brake becomes insensitive. Therefore, it is advisable to regularly check the height of the brake fluid on a monthly basis and pay attention to whether there is a significant drop in the fluid level of the brake fluid and whether the quality deteriorates. If so, it should be added or replaced in time.

Solution: The storage tank of brake fluid for aerial vehicles is made of translucent resin. If the tank can be wiped with a cloth, it can be easily visually inspected. The brake fluid should reach the base line of the storage tank. If the brake fluid is greatly reduced from the previous inspection, there is a high probability of failure and leakage may occur. At the same time, the manual transmission is equipped with a clutch, which also requires attention to its fluid volume. If the fluid volume is reduced and air enters, it cannot be effectively braked.

Second, check the brake fluid every 10,000 kilometers

Appearance: The brake pads and brake discs (drums) of the aerial vehicles have a service life and must be replaced when they are worn to a certain extent. Generally in the city, the life of the brake disc (drum) is approximately 50,000 kilometers, and the life of the brake shoe is approximately 30,000 kilometers. However, the specific situation depends on the operation of the owner.

Solution: Brake shoes for aerial vehicles are best checked every 10,000 kilometers. The brake fluid is generally replaced every 50,000 kilometers. If the vehicle is driven in a humid area for a long period of time, the oil change cycle should be appropriately shortened.

Third, abnormal circumstances carefully check

Appearance: Brake fluid pipe is likely to be encountered when the aerial working platform is undercarriage; when the brakes are applied, the aerial working platform is obviously deflected to the left or right; the brake pedal is stepped to the end, but the braking effect is not obvious. And there is no improvement in the effect of continuously pressing the brake pedal.

Solution: After stepping on the bottom of the aerial working platform, step on the foot to brake, and get off to check if there is any deformation or leakage of the tubing. The deviation of the aerial working vehicle is caused by the non-synchronous front brake, which makes it easy to grab the left of the brake. Right) Accidents occur, especially at high speeds. The brakes must be adjusted immediately at the repair shop. The weak braking effect may be due to the presence of gas in the brake system, which must be repaired by a professional repair station. If there are problems such as too soft pedals, long strokes, etc., also check the maintenance point for inspection.

In addition, after the long-distance operation of the aerial working vehicle, the braking system should be carefully inspected to check whether there is bump, damage and leakage in the brake pipe of the aerial work vehicle because the flying stones hit the high-altitude operation vehicle at high speed. The brake fluid tube on the chassis may cause the brake fluid to leak or the brake to malfunction. If the brake fluid tube is flattened, it may cause the brake failure of a single wheel.

Vessel Production Cutting Machine

The CNC cutting machine has the characteristics of fast cutting speed and small slit in the cutting process, which may lead to limited actual cutting speed, excessive kerf and uneven cutting surface, and eliminate the mechanical failure of the plasma CNC cutting machine. Failure to properly set the plasma CNC cutter related parameters during operation will also affect the actual cutting effect.

The hub processing parts of large ships are concentrated in the base of high-power diesel engine, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and gearbox drive shaft, rudder shaft and propeller, etc. The material is special alloy steel, which is generally processed in small batches and requires a processing yield of 100%. The hinged parts have the characteristics of large weight, complicated shape, high precision and large processing difficulty. Large-scale ship pivot processing requires high-power, high-reliability and multi-axis heavy-duty, ultra-heavy CNC cutting machines.
