Benefits of mountain tower construction:
1. Two fire-proof observation towers are built in the mountainous area, and the whole mountain can be seen, standing high and far away, eliminating the blind spots of despair and saving a lot of manpower. 2. With fixed watch towers and indoor visits, the rangers can protect themselves from wind and sun on the one hand, and they can also focus on forest fires on the other. 3. The construction of forest fire prevention observation towers will better reflect the policy of “prevention first and active elimination”, to ensure the safety of people’s lives and property, and to protect mountain forest resources.
Product Advantages:
1. Small area, saving land resources;
2. The tower has light weight, convenient transportation and installation, and short construction period;
3. The structure is scientific and reasonable, the craftsmanship is excellent, the appearance is beautiful, safe and durable, and the anti-corrosion time is long.
Product parameters:
1.fixed design wind speed: 30M/S (different from region to region) 2.Wrapped ice: 5mm-10mm (different from region to region) 3.Seismic intensity: 8° 4.Suitable temperature: -35℃∽45℃ 5.Vertical deviation: <1/1000 6.Grounding resistance: ≤4Ω 7.Anti-corrosion treatment: hot-dip galvanizing of the tower body steel components. 8.Service life: guarantee 30 years of safe use.
