The risk of having crane legs close to the gutter is aimed at allowing construction vehicles to move within the controlled route, while avoiding turning ground protection issues into equipment stabilization problems. With regard to heavy cranes and transport sites around transformers, wind and large-scale electrical equipment, the subject is concerned with “the risk of a crane leg approaching a gutter”, which should, inter alia, check for repeated vehicle traffic to create a deep path and damage the ground. Where there is a gutter, backfilling area, slope or unknown underground facility on the route, the treatment must first be confirmed by the responsible party of the project.
The product configuration cannot be determined by area or thickness alone. The project shall verify the maximum retroactivity of the plant ' s leg, the position of the leg, the ground-based allowance for pressure, the distance of the gutter from the edge, the suspension radius, the transport axle and the change in rainfall, and then repeat the vehicle traffic into a deep path and damage the ground-level conversion to drainage, carrying, stabilization, surface pull and restoration requirements. The handling tools, manual weights, back-up quantities, cleaning and back-to-back storage are also taken into account in the ICP around the validation of sutures, grass-roots and vehicular operations through representative trial workshops. For “Risk of crane legs close to trenches”, the information review should also identify the broadest vehicle profile, internal wheel differentials and side safety residuals, and include missing information as items to be confirmed in the quotation and construction programme.

In the absence of space on the ground, work cannot be undertaken by reducing the necessary cover or moving legs to the shoulder of the road. Stations and construction should be re-ordered to provide enough space for “sew, ground and vehicle operating space through representative trial workshops”. The area of the leg pad shall be determined by the maximum retroactivity in conjunction with the confirmed ground-based load, and the pavement shall not automatically replace the accounted hanger operating platform. Any forced overlays of holes, temporary mats or uncounted should be returned to the technical manager for evaluation. The test-pail record of the “risk of a crane leg close to a gutter” should indicate the starting point, the vehicle's condition and the release conclusion, to facilitate review as the construction conditions change.
The maintenance plan should include responsibility for key sections and feeder points, frequency checks, decommissioning thresholds and spare parts locations. The re-examination of sutures, ground floors and vehicle operating spaces through representative trial workshops allows for the timely detection of repeated vehicle traffic and the creation of deep and ground-levels. Backup panels, connectors and handling tools are also synchronized to avoid mismatches in specifications on site. The inspection forms, which revolve around the “risk of a crane's legs close to the gutter”, require that the repeated traffic of a single vehicle create a deep path and disrupt changes at the grass-roots level, and indicate the time of the repeater and the resumption of traffic.
The full life-cycle costs include procurement or leasing, shipping, unloading, laying, inspection, cleaning, maintenance, warehousing and ground restoration. The project should compare the cost of implementation of sutures, grass-roots and vehicle operating space through representative trial workshops with the costs of stoppages or repairs caused by repeated vehicle traffic and destruction of the grass-roots level, and not be determined solely on the basis of single-block product prices. It should also answer the question of whether “the risk of a crane's legs coming close to the gutter” has been demonstrated through a representative trial shop to verify the improvement of panels, floors and vehicle operating space and to avoid the closure of the item by a subjective description only.
The ultimate goal is to allow heavy cranes and transport sites for transformers, wind and large-scale electrical equipment, with a focus on “What is the risk of a crane leg approaching a gutter” operating continuously with clear limits and acceptable risks and successfully restoring the ground after completion of work. It is only by connecting the design, product, operation, inspection and evacuation sites that vehicle traffic is repeated into deep space and the ground is destroyed.
