Unboxing and Lifting

◆ Lifting Precautions:

Safety measures, anti-overturning measures for cranes:

◇The site roads for crane operations must be level and firm; backfilled soil and soft soil layers must be treated. If the soil is soft, a separate road should be laid. Cranes must not operate on slopes and it is not allowed for cranes to be unevenly elevated on both sides. Overloading for lifting is strictly prohibited.

No slingshot lifting. Slingshot lifting can cause overloading and wire rope to come out of the groove, even leading to rope breakage and overturning accidents. It can also cause heavy objects to swing rapidly after being lifted, potentially injuring people or other objects. The slings used to tie components must be calculated. All lifting equipment should be inspected regularly, and damaged items identified. The tying method should be properly secured to prevent rope breakage or slippage from the components during lifting, which could cause the crane to lose weight and tip over. The crane's lifting capacity must be within (weight) limits. Lifting operations are prohibited in winds of六级.

Commanders should use unified command signals, which must be clear and accurate. Crane operators should comply with the commands.

Preventive measures against high-altitude falls:

Operators must properly use safety belts during high-altitude work. The belt should typically be hung high and used low, with the hook at the end attached to a high point while the operator works below. When working at high altitudes, the person must be steady, and if there are nearby micro scaffolds or assembled components, one hand should hold them while the other operates. The depth of the extreme tapping should be gradual, especially if the distance is considerable; it's not advisable to rush. If workers need to work at high altitudes, temporary work platforms should be set up as much as possible. These platforms are tool-type, with dimensions of 08~10m, temporarily secured to the upper part with angle iron. The installation height should be 1.0m-12m below the ground level, allowing workers to perform truss alignment and welding. When walking on the upper chord of a suspended high-level circular frame, safety railings should be set up. Ladders used for climbing must be sturdy. They must be securely tied to fixed components with a rope. The angle between the ladder and the ground should generally be between 65~70 degrees.

◇Operators should remain focused when crossing scaffolding planks to prevent stepping on the leading edge. When installing floor or roof panels with pre-drilled holes, cover them promptly with wooden boards.

Note: Operators are prohibited from wearing hard-soled leather shoes during high-altitude work.
