Climbing Elevator Shaft Concrete Placing Booms

Ship mounted HGC38 Concrete Placing Booms: 1. Max. placing radius: 38.8m; 2. Rotary speed: 1450rpm

 Ship mounted Concrete Placing Booms: HGC38

Main Features:

 The structure of boom is optimized by adopting advanced design and technologies such as finite element analysis, dynamics emulate, model analysis, sample machine test, etc. Imported high strength steel ensures high quality and reliability;Key components such as boom and vertical column adopt overall heat treatment to control residual stress and deformation efficiently; Through assembly welding, the vertical column is of high interchangeability; With the proportional control technology applied in multi-valve, the change of boom's motion speed can be changed at random by adjusting the angle of driving handle, which is of superior operating performance; With remote control distance up to 100 meters and four optional frequency ranges, simple and reliable operation could be carried out;Diversified installation modes of the boom includes floor type, elevator shaft type, wall type, ship mounted type and tower type; The embedded parts can be recycled; Two inter-locked working status of placing and climbing enhances the safety and reliability of climbing process; Application of double-layer anti-friction transfer pipe, with a service life up to 30,000-50,000 cubic meters, which is 3-5 times of normal pipe;Hydraulic system adopts double-pump variable flow control technology; The second generation placing boom for elevator hoistway installation can be applied for floor installation and elevator hoistway installation; when it is applied for elevator hoistway installation, the retractable outrigger technology is suitable for elevator hoistway with dimension of 2.0- 2.7mand the climbing frame is fully auto-lifted by motor hoist.
