(1), the road on the hoisting site must be smooth and solid, and the backfill soil and soft soil layer should be handled well. If the soil is soft, the pavement should be paved separately. Cranes are not allowed to stop working on slopes, nor are they allowed to be high and low at one side.
(2), it is forbidden to overload hoisting.
(3) It is forbidden to hang obliquely. Inclined crane will cause overload and wire rope out of the groove, and even cause rope breakage and rollover accidents. The inclined crane will also make the heavy objects swing quickly after leaving the ground, which may hurt people or other objects.
(4) The slings of binding members shall be calculated. All lifting tools should be inspected regularly and damaged tools should be identified. The binding method should be correct and firm, so as to prevent the sling from breaking or slipping off the component during hoisting, causing the crane to tip over due to weightlessness.
(5), don't hang the main components and equipment with unknown weight.
(6) It is strictly prohibited to carry out lifting operation under the condition of six-level wind.
(7), commanders should use a unified command signal, the signal should be clear and accurate. The crane driver should obey the command.
