In 2022, Quanzhou Jingli Engineering And Machinery Co., Ltd., the railway excavator series JG80LT Sleeper Changer Machin won the "Beauty of Manufacturing" Trophy of 2022 manufacturing and processing machinery on the manufacturing platform in China, which is a great encouragement and affirmation for our company and employees. We will make more efforts to build high-quality excavators. Better service for customers, let customers satisfied, win-win cooperation, create brilliant.

At 10 o 'clock on February 27, 2023, Quanzhou Jinli Construction Machinery and technicians from a railway company in the Philippines formally met, and the two sides had a friendly conversation. Lead customers to visit the factory in the morning, watch the actual operation of railway excavator machines, and feel the production process of railway excavator machines on the spot. At noon, we will have a special lunch in Quanzhou. After an afternoon break, the two sides discussed the details of railway machinery. The meeting lasted about two hours. At four o 'clock in the afternoon, we took the customer to Wudian City of Quanzhou to experience the characteristic ancient buildings of Quanzhou, appreciate the local customs and customs of Quanzhou, and took a photo with the customer.

1. First of all, we need to remove the pin sleeve on the bucket and put it aside for use. 2. Use the butter gun to inject the butter into the hole sleeve of the drill rod of the hydraulic crushing hammer, install the drill rod, and nail into the bolt. 3. Put the front sleeve of the forearm of the excavator into the ear plate of the hydraulic crushing hammer shell, install the pin pin sleeve, manipulate the forearm of the excavator, lift the crushing hammer, and put down the small police "ox bone" to install another part of the pin pin sleeve. 4. Connect the hydraulic tubing on the forearm and the middle cylinder block of the hydraulic crushing hammer with two high-pressure hoses. Tighten the bolt and open the valve of the hydraulic tubing on the forearm. 5. Because most excavators have reserved oil port joints for installation of accessories when leaving the factory, when installing the crushing hammer, it is only necessary to connect the pipes, joints and crushing hammer together according to the requirements of the instructions.

Characteristics of rubber track walking system Rubber crawler has the characteristics of light weight, small vibration, low noise, large adhesion, good ground adaptability, no damage to the road surface, etc. Especially suitable for urban road construction, the basic structure of rubber track and steel track is the same, usually by the guide wheel, supporting wheel, driving wheel, support wheel, track and walking frame and other parts, its main differences and characteristics are: (1) The rubber track is the whole continuous eyebrow belt moulded by rubber, the heart is strengthened by fabric and a number of steel cables, the outside is equipped with a shoe, and the inside is equipped with a transmission part. The steel drive is embedded in the vulcanized rubber belt. The main parameters of rubber track are pitch, number, track width, pattern and embedded metal parts (2) The driving wheel is installed on the walking reducer, which is used to wind the track to ensure the mechanical running operation. The driving wheel of rubber track adopts convex tooth shape and pitch is 128mm. Bending stress in the working process of overburden belt will cause fatigue damage, so the driving wheel diameter is not too small (3) The support wheel, support wheel and guide wheel are straddled on both sides of the track teeth, pressed on the rubber plane, in order to prevent rim cutting and serious rubber pressure and damage, so the rim width: because the teeth are higher, so the wheel body is larger.
