freight elevator construction      

SC200/200 the DMK and SC200/200 bm multi-functional construction lifter (hereinafter referred to as multi-purpose ladder) is to comply with the demand of the current thermal power plant cooling tower, the chimney construction specially developed new products. It is adapt to the construction of efficient, fast, economic and security requirements, achieve multi-usage, can transport steel, concrete and construction personnel of sanhe type equipment, bringing great construction enterprise use, avoid the repeated purchase of equipment, saved money.
Features:
Top drive system in cage, reducing cage noise, make the hanging cage clearance increases, at the same time also make driving more smoothly, body vibration smaller, corrosive heavy design simplifies the installation process;
Multi-usage, on the basis of the construction lifter installed a device of steel bars and concrete delivery device, delivery of steel, concrete and personnel, greatly improve the efficiency of construction;
Multiple changes of adhesion system, can make the machine in complex structures.
Novel and chic cable pulley system, to avoid the cable twisted around each other in the process of operation and damage, the impact on the grid and reduce the equipment is started up, extend the service life of the electrical system;
Safety device is complete, reliable, and meet the national standards for safety device with, make the machine working reliability among the top of the same products;
This superior product performance, high efficiency, has been applied many turbine construction departments across the country, is the ideal equipment of construction mechanization and modernization;
Construction lifter working principle:
Hydraulic oil made certain pressure vane pump, the oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, balance valve into the lower cylinder, the hydraulic cylinder piston upward movement, improve the weight, the upper cylinder oil return by the flameproof electromagnetic directional valve back to the fuel tank, the rated pressure through the overflow valve adjustment, observing the pressure gauge pressure gauge reading values.
The hydraulic cylinder piston downward motion (both weight down). The oil in the hydraulic explosion-proof solenoid directional valve to enter the upper cylinder, and the lower cylinder oil return the balance valve, hydraulic control one-way valve, throttle valve, flameproof electromagnetic directional valve back to tank. To make the weight fall calm, safe and reliable braking, set the balance valve on back to oil, balance circuit, maintain pressure, make the falling speed is not affected by weight changes, the throttle valve flow adjustment, lifting speed control. In order to make safe and reliable braking, to prevent accidental, increase the hydraulic controlled check valve, hydraulic lock, ensure the safety of burst in hydraulic pipeline accident can self-locking. Installed the acoustic alarm overload to distinguish overload or equipment failure.
Electric control system through the explosion-proof button SB1 - SB6 to control motor rotation, flameproof commutation of electromagnetic directional valve, in order to keep the load lifting or lowering, and adjust the amount of time delay, by the "LOGO" program to avoid frequent starting motor and affect the service life.
