At the scene, when a mine crane is repaired, many teams ask how thick the plates are needed; however, the key to the calculation of the area of a mine vehicle's latte is to confirm the defunct boundary. If the maximum retroactivity of the leg exceeds the ground-based allowance when it is sunk significantly after rainfall, full load or continuous operation, the state shall be used as a design condition and shall not be replaced by clear or airborne data.
The selection may take three steps: the first step is to verify the work of the crane, the length of the arm, the position of the rotary, the maximum retrogression of the leg, the size of the foot and the ground-based load; the second step is to convert the maximum reversibility of the leg to the carrying, friction, impact or grinding needs when the maximum reversibility of the leg exceeds the ground-based allowance; and the third step is to be implemented to calculate the minimum support area for the manufacturer ' s retrogressive and confirmed endurance. The request for quotation documents should indicate the frequency, life expectancy and maintenance of the leg pads. The increase in thickness usually also increases weight and handling difficulties and therefore cannot automatically be equated with “more suitable”.

Prior to implementation, a pre-operational meeting could be arranged to clarify who confirmed the basis, who tested the income and expenditure legmats and who was entitled to stop operations. The leg pad extended the area of stress but could not repair the unsatisfactory foundations. The site is positioned according to numbering and drawings, and every section completed checks size, edge, connection or rigidity, without leaving all questions to the end. The rhythm should be lowered during the trial period to observe the re-emergence of sank when the maximum reaction of the legs exceeds the ground-based allowance.
The maintenance plan should be designed around sedimentation, slide, edge distance and frequency of underground facilities: each shift at a high-risk point is confirmed, regular spot checks are carried out in the general sector, and additional special inspections are carried out in the event of heavy rains, explosions, overloads or equipment anomalies. When the maximum reversibility of the leg is found to be more than the ground-based allowance, it is recorded that the vehicle on duty and the weather will sink, avoiding the loss of root cause by replacing only surface parts. Scavengers, porters and stacks should be prevented.
The impact assessment cannot be based solely on the availability of the day. More frequent stopovers, cycling times, residues, maintenance hours, surface repairs or equipment can be applied before and after implementation and weather and load differences can be recorded. The fact that the maximum reversibility of the leg exceeds the ground-based allowance would, if it were still frequent, indicate the need to return to the ground, operation or specification boundary for re-analysis rather than simply adding the same product.
It needs to be emphasized that the pedals can only function in an approved operating system. Any overload, peri-side, underground hole, tilt lift or human exposure shall be first disposed of in accordance with the mine rules. This document is not a substitute for the plant manual and the comments of the registered engineering staff; procurement communications should provide a true picture of the most unfavourable conditions of work and avoid lowering the entry conditions to meet the quotations.
