At the scene, when hydraulic fluids in the remediating area contaminate the leg bearings, many teams will ask how thick the sheeting is needed; but the key to the safety of the surfaces is to confirm the defunct boundary. If the film increases slides and covers the cracks that are significantly increased after rainfall, full load or continuous operations, the state should be used as a design condition and not replaced by clear or empty data.
First, the procurement or technical staff shall match the crane ' s condition, the length of the crane ' s arm, the point of return, the maximum retroactivity of the leg, the size of the foot and the ground-based load with the photographs of the site, indicating, in particular, that the occurrence of the film increases the slide and covers the cracks. The programme is proposed to clean, identify leaks and check the pads and floors for reuse, but the length, width, thickness, weight, surface, hole and permitted temperature of the leg pads will have to be checked before implementation. Where products need to be relocated repeatedly, the ceiling for manual removal and mechanical posts should also be included in the selection.

The field organization also decides to use effects. The area of operations should have clear traffic flow, quarantine coverage and abnormal parking standards, and the installation personnel should use loads that match the weight. The leg pad extended the area of stress but could not repair the unsatisfactory foundations. In the event of the discovery of abnormal substrates that continue to sink, feeder overload, liner arches or connects, the use of the substrate must be discontinued and the reasons identified, and the problem cannot be covered by accelerated passage, repeated lifting or temporary pressure.
Maintainers need to know how normal traces of products differ from dangerous injuries. The production of site illustrations around deposition, slide, edge distance and underground facilities is more effective than simply writing “watching”. If the film increases the slide and covers the cracks with increasing use, the payload, foundation or material should be analysed for excess to the original condition and a limit, speed or suspension measure should be applied until confirmed.
If the project is ready to expand its application, it is recommended that it be preceded by a common review of operations, maintenance, security and procurement. Operators confirm the ease of use, maintenance staff confirm the feasibility of inspection and replacement, security personnel check the conditions for decommissioning, and procurement staff deliver spare parts in comparison with spare parts. Multiple opinions can test whether the shutdown is clean, leaks are detected and the gaskets and surfaces are subsequently used for real implementation outside the paper surface.
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.
