  & nbsp; The progress of the hydraulic lifting channel device can also be checked to see if the manufacturer is qualified. Therefore, in the process of installing hydraulic lifting channels, it is necessary to pay attention to the following issues. Adhere to safety production regulations and bring all safety equipment. In case of snow, rain, fog, or strong winds, work is not allowed. Persist in clearing the entrance road constructed externally and providing satisfactory parking equipment space. When using auxiliary devices for steam cranes, the operating conditions of the steam crane should be fully considered.




  & nbsp; Ensure that the power supply device has a superior orientation and a separate distribution box. When using a leakage switch in the distribution box, it is necessary to meet the requirements for the use of the construction elevator. If the construction elevator is controlled by a frequency converter, a frequency converter should be used when selecting the leakage switch.

  & nbsp; Clean the base surface and install the anchor bolts. If the construction elevator is installed on the basement floor, it is necessary to use shims, add nuts at the bottom of the bottom screws, and the surface of the load-bearing floor to reduce the conflict nuts on the floor.

  & nbsp; During the installation process, it is necessary for the welding to be firm and reliable, and the connection of the electrical control system must be carried out by a dedicated electrician. It is necessary to align the connection with the device standards, and it is necessary for special personnel to have unified command during the device process.
