Self-propelled scissor-type aerial working platform lifting part of the connection is used in the scissor type, lifting weight is relatively large compared to other aerial working platforms, is a common aerial working platform in the aerial work; scissor lift stability, lifting weight, but because of his connecting parts of the more, the wear and tear of the bearings between the use of time and increase, so scissor-type aerial Do also the daily inspection of the platform to be more careful, then self-propelled scissor lift daily inspection of what?
1. Check the lift reducer to see if there is oil leakage. If there is a strange sound in the box when running, you have to open the box cover to check. These situations generally occur because of bearing damage or gear meshing backlash is too large, tooth wear and other reasons.
2. Check the performance and condition of the lift brake. Brake is an important part of the lift, directly affecting the accuracy and reliability of the movement of the institutions. Therefore, we should carefully check the condition of the brake of the two institutions of lifting and amplitude, and observe the openness of the brake tile and the wear and tear of the friction components of the brake skin. The belt brake should pay attention to check whether the steel backing of the brake belt has cracks, whether the transmission of the brake is flexible, whether the brake frame is intact and whether the elasticity of the main spring and auxiliary spring meets the requirements.
3. Check the wire rope of the lift. Check the wire rope should first focus on observing the broken wire, wear and tear, kinking, rust and corrosion, etc., for some wear and tear, broken wire is more serious but not yet exceeded the position, with a mark mark, in order to track the review. To pay attention to check the wire rope in the drum in the limiter is effective, the drum on the wire rope pressure plate is pressed and pressure plate number is appropriate.
4. Inspection of the lift pulley. Check whether the amount of wear on the bottom of the groove exceeds the standard and whether there are cracks in the cast iron pulley. The equilibrium theory of the pulley group is easily neglected because of no action in the usual situation. Therefore, the flexibility of its rotation must be checked before installation, otherwise, the installation can not be automatically adjusted by the theory of balance, there will be operational hazards.
5. Check whether the connecting joints of the lift are loose or even "rolling key". Focus on checking the bearings and connecting parts that have wear parts during operation, and check whether there is wear. Tooth connection should pay special attention to its gear ring wear condition. Due to poor installation accuracy, in the case of a large offset between the two bearings, the performance of a short period of time the real gear ring will soon wear bald. Lift easy to wear parts of the machine bearing joints long-term wear will reduce the stability and durability of the whole machine, and even long-term unchecked, there may be the use of sudden breakage, the danger.
In short, the safety of aerial working platform is a problem that can not be ignored, the above is about self-propelled scissor-type aerial working platform daily inspection of several items, the operator should pay attention to the use of the equipment should be often checked, repaired and maintained, to ensure that the equipment is running in a normal and good condition, to avoid the emergence of any sudden situation.
