 Screw Jack System for Jump Form

Hangzhou Ever-Power Transmission Co., Ltd. is a professional reducer design and production factory. Our company has been operating for many years and can provide customers with spiral elevators, screw elevators, worm gear reducers, secondary enveloping reducers, and other high-quality products. The quality and performance of these products can be guaranteed to users. At the same time, in addition to producing standard models of reducers, we can also provide non-standard customized services.

Jump Form

Generally, form jump systems (including systems commonly referred to as “climbing forms”) include forms and working platforms for cleaning and fixing forms, steel fixing and concrete pouring. Formwork is supported on previously placed concrete and therefore does not rely on support or access from other parts of the building. The jumping formwork system is applicable to the construction of vertical concrete components in high-rise structures, such as core walls, elevator shafts, stairwells and piers. The system is usually modular and can be connected to form long lengths to adapt to different structural geometries.

Self climbing form jumping systems do not require cranes because they climb onto the rails on the building by means of hydraulic jacks or by jacking the platform away from the grooves in the structure. Multiple units can be promoted in one operation. Working platforms, guardrails and ladders are usually built into a complete formwork system, and where necessary, complete wind deflector protection shall be provided.

A screw jack is a mechanical transmission device used to convert rotary motion into linear motion, which is suitable for a wide range of industrial applications. They include a worm gearbox mechanism in which the alloy steel worm rotates a high-strength bronze worm gear. The rotation of the worm gear causes linear movement of the lifting screw or the moving nut on the screw. The screw jack can realize the linear motion solution of precise positioning and smooth operation. They can be used for load capacities from 5kN to 2000kN. The linear motion speed and bearing capacity of the lifting screw depend on the worm gear's thread size, pitch, and rotation ratio.

Construction elevator &  Hoist parts

The construction elevator, also known as the construction elevator for building, is a frequently used construction machinery for carrying people and goods. Because of its unique box structure, it is comfortable and safe to ride. The construction elevator is usually used in conjunction with the tower crane on the construction site, with a general load of 1-3 tons and a running speed of 1-63M/min. The structure principle and characteristics of the construction elevator: In order to meet the needs of the construction of inclined buildings such as bridges and chimneys, the construction elevator inclines the guide rail frame according to the shape of the building, while the cage is kept horizontal and runs up and down along the inclined guide rail frame.

Scaffold parts for construction machinery

Scaffold is a working platform erected to ensure the smooth progress of each construction process. It is divided into external scaffold and internal scaffold according to the erection position; It can be divided into wooden scaffold, bamboo scaffold and steel pipe scaffold according to different materials; It can be divided into pole scaffold, bridge scaffold, portal scaffold, suspended scaffold, hanging scaffold, cantilever scaffold and climbing scaffold according to the structure form.
