Description

Features:

The tool-type foundation pit suspension step ladder is composed of a triangular bracket fixed on the top of the slope protection pile of the foundation pit and a cross-plate tower ladder suspended at the bottom of the bracket. The construction channel formed is spacious and comfortable to walk, which can meet the needs of personnel during the construction of the foundation pit. The upper and lower passage requirements of the product; the product components are all standard parts, and the pin-bolt connection structure is adopted to meet the needs of different structural forms of the foundation pit. The installation and disassembly are simple and high-efficiency; the cross-tower ladder is a standard section combination structure, which can be excavated with the foundation Gradually extend to the bottom of the foundation pit, and remove it layer by layer as the foundation pit is constructed upwards to flexibly meet the requirements of the construction process during the construction of the foundation pit; except for the cooperation of hoisting equipment during the first installation and final removal, no other lifting is required during the construction process Equipment coordination can save the use times of tower cranes.
