Donam Engineering Co., Ltd. Acquired UCMP certification for hydraulic elevator unit and control panel First in Korea for hydraulic elevators, satisfying customer satisfaction and safety simultaneously
Donam Engineering Co., Ltd.(representative Jinha Jin, www.donam.co.kr, hereinafter referred to as DONAM), a company familiar with hydraulic elevators that have manufactured cylinders, hydraulic units and oil coolers for hydraulic elevator since 1989, It has secured its position in the hydraulic elevator market by acquiring the conformity assessment and certification of the UCMP(gate opening prevention device) of elevator unit and control panel.
As the hydraulic unit required the installation of pressure shutoff valves for UCMP under the revision and approval law last year, DONAM has developed a pressure shutoff valve and control panel to improve the quality of products and provide better customer satisfaction services.
UCMP is a device that can prevent unauthorized operation of passengers in the event of a brake failure of the elevator control system or driver, without locking the landing door in the congested section, in order to protect the passenger from the risk of injury. This device shall be capable of detecting uncontrolled movement before the car moves 1,200mm from the platform and must completely stop the car and meet the requirements of the inspection criteria.
Jinha Jin, DONAM said, "Since the company was founded in 1989, we have not allowed any safety accidents, and we have obtained certification for maximum pressure of 70kg/cm^2 and speed of 60m/min, The combination of the hydraulic unit and the control panel has resulted in higher sales and customer satisfaction".
In addition to the hydraulic lift unit and control panel, which recently acquired the UCMP certification, DONAM obtained a safety evaluation certificate for a rupture valve, which is a safety device that gradually stops the car in descending order. In addition, a practical design such as a mounting guide structure of a hydraulic cylinder rod, a oil recovery device, etc. was obtained, and a patent for a cylinder head design was also filed.
DONAM has been continuously investing and developing technologies for multi-stage cylinders(2-stage, 3-stage), oil cooler, oil heater, level compensator and related parts for hydraulic elevators. Particularly, re-leveling device and multi-stage cylinder dedicated to home lift are regularly tested for upgrading products from hydraulic test towers on the side of factory entrance.
"We are making efforts to convey more impressive technology such as complete CNC machining equipment and painting equipment, cutting, processing and painting raw materials through our own production process. In the first half of this year, plans to be more complete in the field of installation". In addition to product development, DONAM also strives to improve employee welfare. It has been steadily promoting welfare policy for the sense of belonging and harmony, such as the payment of night work allowance, childcare allowance, child school tuition support, incentive payment, and so on. Through its own enterprise resource planning(ERP) program, it shares the status of supply and repair parts, sales and supply, and ordering and delivery contracts with all employees.
Recently, he has been publishing a technical resource book for 10 years, and he is expecting the second generation to prepare for the succession of the family business.
