Construction Machinery

From 2017 to 2021, Jinlong has successively cooperated with HANGCHA Group, and has undertake spray production line for bridge-box, gantry, climbing truck, electric fork frame, storage truck parts and counterweight line. The highest cycle time of the production line is 35s/piece, and the lowest is 2.5min/piece. The work-piece weights 300~2500 kg.

In 2019, Jinlong provided service for Zhejing DINGLI. Finished the powder spray production line for structural parts and sheet parts, large arm and curved arm parts powder spraying line, shear fork lift truck GA line, large arm and curved arm GA line, and painting line for balance weight. The production rate of the production line is 1.5 min/piece at the fastest and 10 min/piece at the slowest. The weight of the work-piece is 300~7500 kg.

Coating conveyor line is used to finish automatic conveying process for work-piece from load station to discharge station (loading, shot blasting, pre-treatment, water blowing, moisture drying, forced cooling, grinding repair, powder spraying, powder drying, forced cooling, discharge). The conveyor system is controlled by PLC, which is convenient for interlock and synchronization with other large equipment. Which realizes the automatic monitoring and tracking of the whole line, makes the mass production and organization more effectively.

Conveyor design meets the requirements in “Made in China 2025", bring out the automation and intelligence of the product. Considering practicability, progressiveness and economy, while ensuring the smoothness of the entire coating logistics. Based on the principle of advanced technology, improve the process level and equipment level of the coating workshop, and at the same time paying attention to the practicality and economy of the process and equipment.

Implement the principle of "safety first and civilized production"; Meet product quality and process requirements; The equipment design meets the requirements of relevant national standards and specifications. Equipment design conforms to the technical requirements in the bidding and the requirements of attached layout plan. Each equipment of coating line was designed per production program and process flow to finish painting requirements. It makes full use of workshop area and take into account the connection between each process, which ensure the reasonable layout, and strong support smooth logistics and convenient production organization; follow the principles of energy conservation, environmental protection, consumption reduction and investment reduction; Pay attention to energy conservation measures of equipment and use energy reasonably. Ensure that painting, drying and other areas are closed independently.

The process design is specific per each work-piece, to improve the corrosion resistance and decoration ability, as well as appearance quality of it. All equipment involved in the production line must be painted uniformly according to the safety marking color. It should be easy to maintain and meets the safety maintenance management standard. Strictly implement relevant national laws, regulations, standards and specifications, and emphasize environmental protection, fire protection, energy conservation and safety in the design. Strictly implement national laws and regulations on labor safety, health and environmental protection, meanwhile consider cost reduction. Noise: low-noise equipment shall be used. The maximum noise around the equipment shall not exceed 85dB, and the ambient noise around the operator shall not exceed 85dB.
