Heavy equipment base preload test is to prevent heavy equipment from the foundation after equipment failure and preventive measures caused by differential settlement install installation. Total alkali base pressure preloading force test should not be less than full load running on the device, based on the observation reference point should not affect the basis of the settlement observation points around in less than four points evenly distributed. Should be regularly observed stable, until now. Observation should be recorded in detail. Heavy equipment installation level is not too high, industrial equipment installation, do not install the basic front preload test, settlement-based observations, only when debugging devices. Allowed unknown weight lifting and buried, the actual weight of the equipment must be clearly object stuck in the ground before the installation of the heavy lifting was not allowed unknown weight lifting and buried, heavy stick in the ground. Lifting point should be chosen weights and center of gravity in the same vertical line, and the lifting point should be above the center of gravity, so vertical lifting weights, hanging oblique prohibited. When lifting heavy objects without a fixed point must be in a specified lifting points and tied securely so that the weight balance and suspension points in the lifting process does not produce displacement.
