What records are required in cases of heavy lifting?

In the case of heavy cranes and transport sites for transformers, wind machines and large power equipment, the focus of the topic is on “what records are to be kept in cases of heavy lifting” and the appearance of flatness does not mean that there is a continuous burden under the plate. What records are required for heavy-lift cases, and the condition of the ground, weather and maximum-heavy vehicles should be recorded before entering the field, as the grade change of the equipment level may occur after repeated traffic due to an overload or uneven deposition of the branch. The establishment of baseline photographs and measurement points will facilitate follow-up inspections and recovery of acceptances.

Four school-specific topics are available at sites, equipment, products and operations. The site and equipment column records the maximum retroactivity of the leg, the position of the leg, the base allowed pressure, the distance of the groove from the edge, the suspension radius, the transport axle load and changes in rainfall. The product column lists the size, thickness, texture, connection and batch, and the operating column indicates that the drainage and soft points are first processed, then laid out from the stable end and tested. Any one still relies on empirical speculation and may lead to a re-emergence of the level of equipment at the peak of the construction, resulting in overloading or uneven deposition of the branches. For “the records to be kept in cases of heavy lifting”, the information review should also include a breakdown of net area, turnovers, back-up and wear and tear, and include missing information as items to be confirmed for quotations and construction programmes.

A smooth transition should be put in place at the different ground crossings to avoid the sudden impact of vehicles on temporary circuits from hard roads. The internal and external wheels and brake positions of the most heavy vehicles will also be reviewed following the first treatment of drainage and soft points and the laying from the end of the stabilization segment and the completion of the trial operation. 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. Physical segregation and clear rules for release are required in the vicinity of public areas. The trial-pave record of “what records are to be kept in cases of heavy lifting” should indicate the starting and ending position, vehicle condition and release conclusions to facilitate review as construction conditions change.

The inspection cycle can be shortened at an early stage of use and then stabilized before adjusting to vehicle cycles and weather. The maintenance staff focused on mid-legged, full-contact, mat deformation, deposition, horizontal, edge-opening, road stitches and transport wheels, and observed whether drivers complied with speed limits and turnover requirements. Any unconfirmed sub-board support, edge instability or foot contact should first be disabled. With regard to the “remaining of records in cases of heavy lifting”, the inspection form requires a single column to overload or even down to change the level of the equipment and to indicate the repeater and the time of return.

The offers from different suppliers should be compared under the same size, material, connection, packaging, delivery and test basis. Supplementation should be requested if the maximum load is given without a description of the ground, distance and load. Energy projects should also focus on batch consistency, port efficiency, repairability and container loading. It should also answer whether the “records to be kept in cases of heavy lifting” are improved by first dealing with drainage and soft spots and then by laying and piloting at the stabilization end to avoid a subjective description of the end item.

Road-painting and foot mats can only function in the approved construction system and cannot be a substitute for unsatisfactory foundations, damaged equipment or irregularities. Any unknown underground facility, unstable edges, legwork beyond the equipment manual or failure to isolate persons should be suspended and upgraded.
