Lanzhou general Electromechanical Technology Research Institute   

Lanzhou general Electromechanical Technology Research Institute was founded in 1989, Gansu province science and Technology Commission identified as "high-tech enterprises". Mainly engaged in new technology, new technology, new product development, development, production, sales. We have strong design and technical development strength, perfect quality assurance system, and science and technology development, research, production mechanism. This product is suitable for the bridge type and door type crane, can effectively prevent and eliminate the crane hook lifting over hoisting movement (commonly known as the "roof") and down motion of the anti hoist accidents, is the ideal replaced product upgrade. Products comply with GB6067-85 "The relevant requirements of safety regulations" crane, product implementation of Q/LZTD01-03 and JB/4315-97 standard. The principle of automatic control of the product application, the use of worm gear reducer to drive the target and the pressure head rotation, with no contact, no pressure, no spark electronic sensors and micro switch control. Features of novel conception, reasonable structure, high repeat accuracy, limit is accurate, complete functions, high reliability, the upper limit of two lines of insurance, the lower limit of two lines of insurance, the key is to be able to in a dangerous position on the hook, forcibly cut the winch motor main power circuit, and is provided with four individual function.
