The stepping type hoisting platform comprises a working table board, positioning locks, a moving bracket, a pedal, a pedal bracket, a steel cable, a supporting framework, a steel cable connector, crosspieces, a pulley, a resetting spring and a table board bracket, the platform is characterized in that the supporting framework is provided with the plurality of crosspieces; the table board bracket is sleeved on the supporting framework; the moving bracket is mounted in the table board bracket and is sleeved on the supporting framework; the working table board is fixedly connected with the table board bracket; the working table board is provided with a first positioning block and the moving bracket is arranged above the working table board; the moving bracket is provided with a second positioning lock; one end of the resetting spring is connected with the bottom of the moving bracket; the pedal is arranged between the moving bracket and the working table board. Compared with the prior art, the stepping type hoisting platform has the advantages of simple structure, low construction cost, accordance with human engineering, capability of meeting the requirements of different working types, high safety, light weight, convenience for carrying, high working efficiency and convenience for installation.

Description

[technical field] [0001] The invention relates to the technical field of lifting devices, in particular to a stepping lifting platform. [Background technique] [0002] Traditional high-altitude operation equipment mainly includes ordinary climbing ladders, electric drive lifting platforms, movable scaffolds, pedal lifting platforms, etc. Although the climbing ladder is simple in structure, easy to operate and carry, and has a strong cost advantage, its application range is limited due to its poor safety, low lifting height, specific support, and lack of ergonomics. Movable scaffolding is a common high-altitude operation equipment in construction sites, mainly through the splicing of multiple steel pipes to achieve the required working height. Movable scaffolding has high stability, safe and reliable work surface and low cost advantages, but the installation is cumbersome, the work efficiency is low, there is a certain degree of safety hazard, and it does not conform to ergo...
