When using voltage file to detect elevator equipment, it is necessary to turn on the power supply, then measure the voltage according to the circuit schematic diagram, and determine and analyze the fault point through the measured voltage value. When checking the resistance file, it is necessary to disconnect the power supply, then measure it through the circuit schematic diagram, and analyze the fault point according to the measured resistance value.
When using multimeter to check the fault of elevator equipment, it can be detected by resistance file and voltage file. When inspecting elevator equipment lines, there should be on-site maintenance personnel to prevent switching switches during inspecting lines, leading to safety accidents.
When using short circuit method, the control chart of elevator equipment can be used. Short-circuit the faulty contacts and switches that may occur. After short circuit, if the fault is eliminated, the fault is in this part. After narrowing the scope, check again to find out the location of the fault.
Line failure occurred in elevator equipment. After the report is completed, relevant departments and manufacturers provide timely feedback. It is very important to ensure that the power supply is disconnected when repairing the circuit to ensure the safety of the inspector so as to check the escalator for minor problems more quickly.
Lifting cargo elevator is a kind of lifting machinery. It can manually carry out upper and lower transportation through the button operation of the control system. The lifting height of elevator equipment ranges from 1 m to 20 m, which can be customized according to user's requirements. Customized special lifts. According to the model, it can be divided into: scissors lift cargo elevator and railway lift cargo elevator. Railway elevator is a non-cutting fork cargo ladder. It is mainly used in the workshop on the second and third floors. There are no pits and machine rooms. Factory, steel structure workshop, hotel, basement, warehouse floor cargo transshipment, fork lift cargo elevator need to do well in advance, install lift cargo elevator into the tunnel fixed connection, connect the power supply can be used.
When hydraulic power unit is used to generate pressure, hydraulic cylinder is the main power to drive the elevator platform to rise and fall. When the rail-type hydraulic elevator fails, it can stop running immediately, with high safety and stability. Driven by hydraulic power unit, it has strong bearing capacity and stable lifting. It can realize large-scale transportation of tonnage goods.
