Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and more particularly to an adjustable mobile hoisting device in a restricted space and an operating method. BACKGROUND

[0002] As an efficient and convenient vertical transportation tool, escalators are widely used in commercial and shopping places, public transportation hubs, hotels and tourism services, and many other public places and commercial facilities. The use height (i.e. vertical lifting height) of the escalator needs to be designed according to the specific application scenario, safety standards and technical specifications. The escalators in different application scenarios have certain differences in lifting height, mainly due to the differences in use environment, passenger flow and safety requirements. According to different requirements, the conventional design maximum height of the escalator can reach 15m, and its installation has certain safety hazards.

[0003] The traditional escalator construction method is to transport the escalator components to the construction site, use hoisting equipment to safely transport the parts to the installation position, first use a simple hoisting method to install the truss, and then install the driving system and electrical system. The truss is the main support structure of the escalator, which carries all the components, and is usually made of angle steel, profiled steel or square and rectangular pipes, etc. The truss is divided into two types: integral welding and split welding. The higher the height, the wider the steps, and the heavier the weight. The maximum truss weight in the 15m height range can reach 4.5 tons.

[0004] The traditional hoisting method usually installs a hoist on the top of the floor or uses a simple welding device. The construction process has risks and is prone to cause personal injury or damage to goods.

[0005] Therefore, how to ensure the safe installation of the escalator during installation is a difficult problem that technicians in the field have been thinking about. SUMMARY
