Construction Hoist Steel Structure
Construction Hoist Steel Structure means the construction hoist spare parts like Construction Hoist Mast Section, Passenger Hoist Cage, Construction Hoist Wall Tie and so on.
The length of each mast section is 1508mm, the rack is fixed on the mast by three bolts and it can be exchanged. For the single cage hoist there is only one rack on the mast section, and the mast section can be used for the double cages hoist by increasing one rack. The section of the mast is diverse, select one type section according to different hoist. The mast sections are bolted together with M24 bolts and nuts to form mast. The mast is tied to the building with tie-in and is the guide rail of the cage. According to the user`s or circumstance`s request, surface of mast is hot dip galvanized, which can prevent it rusting.
The tie-in(wall tie) is the linked part between mast and building, to keep the stabilization of the mast. Distance between the tie-in is about 6~9m alone the mast. There are several types of tie-in. Select one of them according to need, tie-in can adjust the vertical of mast in definite ranges. According to the user`s or circumstance`s request, surface of the tie-in is hot dip galvanized, which can prevent it rusting.
The cage dimension(L×W×H)(m): 3×1.5×2.5. We can also manufacture cages of other size according to the user`s needs. The material of the cage and the door material can be steel wire weave, aluminum-plastic panel, punched-plate, figured aluminum board or other type according to user`s needs. The gate is equipped with drawing gate,include small turn over gate.

2. The bottom of the valve sleeve type sewage drain valve is provided with a larger drain hole. If necessary, it must be opened to clean the dirt inside the valve.
3. The sealing surface of the valve seat adopts a taper seal, which is beneficial to the valve itself cleaning the dirt attached to the sealing surface.
4. The valve sleeve of the valve is equipped with a balancing hole and a piston seal to ensure the stable operation under the conditions of full pressure difference between opening and closing. It is light and flexible, and has small opening and closing torque.
5. Filler adopts v-shaped packing structure with self-sealing capacity, no adjustment, and it is extremely light to open and close. There is an auxiliary seal grease injection structure at the stuffing box so that the valve packing seal performance is reliable.
6. The valve sleeve sewage valve can be repaired online. The pipeline can be replaced with a series of wearing parts under pressure.
7. The outer ring of the valve sleeve type sewage valve flap has an o-shaped seal ring, which has a self-cleaning function and sealing when it is opened/closed, and has a throttling and pressure-reducing function when the sewage is discharged.
8. The valve sleeve type sewage valve is a new type of throttling, cut-off, and venting products. The valve adopts cage-shaped fan-throttle throttling, with multi-stage throttling effect, obvious throttling effect, reliable sealing, and convenient operation and maintenance. .
Eight structural features of valve sleeve sewage valve
1. The valve sleeve type sewage valve adopts double seal (hard and soft seal) to make the seal reliable, and the hard alloy cover can be more resistant to airflow erosion and wear. The double seal can achieve zero leakage under high pressure gas medium conditions. Long service life of the valve.
