Suspended platform, as temporary suspended cradle platform, are
widely applied in maintenance applications such as curtain fecade
cleaning in high rise building, painting, glazing repairs, bill- board
painting, cable installation and other outer working of high rise
building up to 150 meters about 30 floors high. Our ZLP series suspended
platform cradle, ZLP1000, ZLP800, ZLP630, ZLP500, ZLP400 and ZLP150, are
good choices for fulfill above outside of wall work. Based on the different materials, the suspended platform could be divided into Aluminum Working Platform, steel Working Platform, galvanized Working Platform.
ZLP series temporarily installed suspended platform is an ideal access equipment for building facade construction, decoration, cleaning and maintenance. It can be also applied to other aerial working such as elevator installing, ship building, construction of dam, bridge, large chimney, etc.
This equipment is easy to operate, convenient to move and reliable in safety and much more efficient than traditional scaffolding.

Smooth blasting is to drill a row of (circle) dense blastholes on the contour or excavation edge so that the resistance line is larger than the hole spacing. When blasting, a rupture zone is formed along the blasthole line to obtain a flat rupture surface. Generally, smooth blasting is initiated once after the main blast hole is blasted or after cleaning. After smooth blasting, the forming is regular, not over-excavating, meeting the design requirements, the new slope is not damaged, and the stability of the step is guaranteed.
The smooth blasting mostly uses uncoupled charge. The open blast and underground mines use this blasting method in the field work. The schematic diagram of the typical scheme is shown in Figure 1 and Figure 2.

Fig.2 Schematic diagram of the arrangement and detonation sequence of the smooth blasting hole in the underground roadway
The charge of each blasthole in rows 1, 2, and 3 is 108kg, 90kg, and 72kg, respectively.
It is necessary to explain that the smooth blasting construction process must be strictly in accordance with the design requirements to ensure the blasting effect.
