Features

Main functions of the product
1, Overweight hoists’ cage protection: When the goods in the cage are more than maximum loading weight, the machine would be automatic shutdown and appear screen prompts.
2, inter-layer door chain protection: When any one of the inter-layer safety door is not closing well or hoists’ cage running suddenly opened, the machine automatically stop running, and have the corresponding prompt.
3, hoists’ cage safety door protection: When hanging cage (security) door is open, the machine should not run and have the corresponding prompt.
4, phase sequence protection: When the power supply phase sequence is incorrect or missing phase, the machine automatically disconnect the power and have the corresponding prompt.
5, over summit, over ground protection: reliable mechanical and anti-summit device (anti-rather than taking it at the end of installation), to ensure over summit and over group of the accident will not happen.
6, motor short circuit or overload protection: When the electrical short circuit or over-use of its rated current, voltage, the machine automatically cut off power.
7, data protection: At any time, switch off the power supply, built-in storage will not lose any data.
8, sensor failure protection: When the sensor fault and result in no signal, it will be detected by computer and promptly shut down, thereby avoiding the failure happened.
9, an external control line low-voltage protection: all external control lines, including upper and lower limit switches, inter-layer door, safety door switches, and pulse sensors are in line with the International Electro technical DC24V safety standards.
10, bell prompted functions: output bell signals before running, the machine remind workers to leave cage of hoists, to protect the personal safety of workers.

1, all Chinese liquid crystal display functions (advanced performance) 2, automatically correct hoists’ cage stop layer position deviation function: in use, due to the hoist’s cage loading weight of the goods different, so that the tensile steel wire rope caused by the location of stop layer bias, as long as a user press inching switch to correct position of cage, the machine automatically correct position, thus no need to use press inching switch to correct every time that to prolong electrical components and avoid mechanical damage and improve efficiency. 3, advance layer doors protection and controlling function: This machine adopts the most advanced digital communication technology, just a four-core cable wire can be connected to dozens of layers door, and can accurately identify all playing, at the same time can identify all open door where located and display on the LCD screen, thus facilitating the operation of staff. 4, four cable wire ropes of machine accurate flat layer: This machine adopts the most advanced data correction effectively to overcome skidding phenomenon of procedure of four cable traction machine, so that the stopping layer traction machine is more accurate. 5, improved version of a high penco: hoist’s cage calculates in meters, after improved, it become more accurately in height, operator can easily grasp/know the location of hoists’ cage. 6, automatic identification of floors: No matter manually or automatically is able to accurately display the current hoists’ cage is located in which floor. 7, built-in walkie and talkie (interphone): This machine has been equipped with clear walkie-talkies; it can be multi-installed and easy to use. 8, the password protection functions: because this machine has more advanced features selection and parameter setting, only the operator enter the correct password to change the memory of the relevant parameters.
