o preventwire rope winch Manual Block to produce a chemical reaction the performance changes

Electric Stacker often use should pay attention to maintenance , especially for electric cars piled high maintenance system to do better , then how do electric stacker hydraulic system maintenance job?
 select the appropriate hydraulic oil:
Hydraulic oil in the hydraulic system of electric forklift trucks passing plays pressure , lubrication , cooling and sealing effect, the inappropriate choice of hydraulic oil hydraulic system failure and durability of the early decline. When grade hydraulic oil should 15 ton electric chain hoist randomly select "Manual" specified in special circumstances need to use on behalf of the oil, it should seek the same performance as the original grade performance. Different brands of hydraulic oil can not be mixed , to prevent hydraulic oil to produce a chemical reaction  the performance changes. Dark brown , white , smelly oil hydraulic oil is bad you can not use .2, to prevent air from entering the hydraulic system mini electric hoist Containing hydraulic fluid under pressure in the temperature volume ratio of 6 to 8% of the air pressure is reduced when the air is free from the oil , the hydraulic components bubble burst " cavitation " noise. A lot of air into the oil will cause " cavitation " phenomenon intensified, hydraulic oil compressibility increases, job insecurity, reduced efficiency , implementation of components appear to work "crawling " and other adverse consequences. In addition , the air also makes hydraulic oil oxidation, accelerated deterioration of the oil.

wire rope winch This is because the laser is directional

Ranging laser light is one of the earliest applications. This is because the laser is directional , high  brightness , good color and many other advantages . 1965 years ago the Soviet Union using laser measuring  the distance between the Earth and the Moon (380 × 103km) error of only 250m. After the Americans landing  on the moon in 1969 set the mirror on the lunar surface , but also with a laser to measure the Earth-Moon  distance , the error is only 15cm. [ 14 ] Although the high -precision laser distance sensor has been  listed for many years , but because of its price is too high , has not been widely used . Recently, due to  the significant permanent magnetic lifter decline in their prices , making it a cost-effective areas ranging approach. After  comprehensive consideration , we decided to take the lead in the industry of weight using laser distance  sensor for non-contact position measurement, this not only ensures the safety test accuracy and test  process can be slipped easily measure the amount of brake weights , lifting parameters such as speed and  position to solve the wire 20 , Southeast University, master's degree thesis ( 1 ) spatial segregation :  Let susceptible to interference away from the interference source crane trolley signal lines or circuits , this is the  most effective measures to suppress interference sources. Avoid parallel lines and the strong and weak  signal line signal lines away from strong electrical feeder lines must go alone . Must not be mixed with  the signal line to pull together ; must take the analog signal and digital signal lines separate line ;  avoid strong signal line parallel with the weak signal line , if the conditions as much as possible so that  the two orthogonal . ( 2 ) Screening: overcoming the electric-field coupling is the most effective method  of interference shielding . Because placed in the hollow conductor or metal objects are not affected by  external electric field . However, when an electric field coupling interference shield , the shield  conductor layer is preferably not connected at both ends

When lifting device can Wire rope hoist not exceed the maximum operating limit table position

the table fence height is less than 1.8m, no sharp edges should be suspended vertically in the lower edge of the bezel anti-collision wellhead floor with flexible member ( such as chain block ) , its sagging height of not less than 0.3m.
5.8.8 the limit position limit
When lifting device can not exceed the maximum operating limit table position, position limits should be set on limiting device to ensure the safety of space at the top table in line with the provisions of 5.5.2 .
5.8.9 anti-fall device
Lifting platform shall be provided to prevent falling or falling speed stage safety apparatus should be 1.6 times
the rated value of Wire rope hoist the table before the rate of decline in function , so that the table is stopped reliably .
In addition to the use of outer table scissor mechanism support or direct jacking cylinder lifting platform , anti-fall device should be connected directly with the table .
5.9 electrical systems and electrical protection
5.9.1 Power Supply System
AC power lifting platform should TN-S power supply system. When the power supply system as a result of the reasons can not be achieved , at least from the outlet end of the beginning of the main power switch , neutral and ground wires should always be separate.
5.9.2 Total Power Switch
