The main content of industrial freight elevator maintenance is cleaning, tightening, adjustment, lubrication, and corrosion protection.


 The mechanical department of each project must strictly perform various maintenance tasks in accordance with the maintenance manual and maintenance procedures of the industrial freight elevator according to the specified cycle, reduce the wear rate of parts, eliminate hidden dangers of failure, and extend the service life of the machinery. Need to do the following:

  1. Routine maintenance: Cleaning, lubrication, inspection, and tightening are all part of routine maintenance. Before, during, and after each shift, routine maintenance should be performed as needed. The mechanical operator does routine maintenance on his own.
  2. Regular maintenance: According to the maintenance requirements of various mechanical equipment, after reaching the specified working hours or specified mileage, corresponding regular maintenance must be carried out, including the following:
  • Primary maintenance: The primary maintenance work is carried out on the basis of routine maintenance. The key tasks are lubrication, tightening, inspection of relevant parts, and cleaning of the “three filters” work (ie clean air, oil, fuel filter) Wait). The first level of maintenance is guided by the mechanical team leader and completed by the mechanical operator.
  • Secondary maintenance: Inspection and adjustment are the main goals of secondary maintenance operations. Check the engine, clutch, transmission, transmission mechanism, steering and braking mechanism, working device, hydraulic system, and electrical system for proper operation, and make required adjustments to eliminate any flaws discovered. The machine operator assists the maintenance people with the secondary maintenance. Lifting table with hydraulics
  • Three-level maintenance: The emphasis is on identifying, modifying, and eliminating hidden problems, as well as balancing the degree of wear of various components. Diagnose and inspect the parts that affect performance and the parts that have problem indicators, then replace, adjust, and troubleshoot as appropriate. Fully-trained maintenance professionals use advanced testing devices and tools to complete the third-level maintenance requirements.
  1. Special maintenance
  • Walk-in maintenance

During the run-in period, new machines or machinery that has been overhauled require run-in maintenance. During the prescribed run-in period, the load and speed should be gradually increased in accordance with the applicable requirements, and the lubrication and tightening conditions should be thoroughly examined, as well as the overall condition of the machine. If any irregularities are discovered, they should be addressed as soon as possible. Running-in maintenance focuses on replacing the lubricating oil, lubricating each component, and tightening each bolt. After the running-in time, perform supplementary maintenance.

  • Seasonal maintenance

The machine should be maintained once a year before summer or winter. The focus is on the fuel-fuel system, hydraulic system, cooling system, and starting system. The following work needs to be done according to the actual situation: replacing the fuel oil and hydraulic oil, adjusting the relative density of the battery electrolyte, taking cold-proof or cooling measures, and cleaning the cooling system.

  • Disable maintenance

When the mechanical equipment needs to be out of service for a period of time due to seasonal factors (such as winter holidays), etc., it should be out of service for maintenance. Mainly do cleaning, plastic surgery, matching, anti-corrosion, and other work.

  • Storage and maintenance

The storage and maintenance should be carefully implemented in accordance with the storage requirements to reduce the erosion of the long-term storage equipment by the natural climate.

  1. The maintenance department shall propose a maintenance plan based on the machinery use plan and supervise the implementation of the maintenance personnel. At the same time, strengthen the inspection of equipment and ensure the quality of maintenance work through verification. Operators should carefully fill in the machinery maintenance records, and the machinery statisticians should sort them into the technical files of machinery and equipment for future reference.
