#### **Product Overview**
This product is a core component of the ultra-large-tonnage lifting system specially developed for 60-ton and above mining dump trucks and engineering transport vehicles. It adopts a multi-stage telescopic structure and heavy-load reinforcement design, capable of providing an lifting force ranging from 800kN to 2000kN, meeting the requirements of high-strength and high-frequency transportation operations of ores and earthworks.

### **Five Core Technologies**
#### **1. Super Multi-level Structure**
- 4-6 level telescopic design (lifting height of a single cylinder: 2.8-5.2m)
- Original **stepwise wall thickness optimization technology** (the wall thickness of the final cylinder reaches 25mm)
- 50% improvement in anti-bias load capacity (patented guide ring layout ZL2023XXXXXX)
#### 2. Intelligent Safety System
- Three-level pressure protection (mechanical/hydraulic/electronic redundancy design)
- Dynamic adjustment of lifting speed (automatically matched according to load)
- Real-time monitoring of inclination angle (±0.5° accuracy)
#### 3. Adaptation to Extreme Conditions
- Mining version: Wear-resistant ceramic coating (resistant to rock impact)
- Cold region version: -45℃ low-temperature starting system
- Tropical version: Resistant to 100℃ high temperature sealed components
#### 4. Long-term Sealing Solution
- The main seal uses the **Turcon® Glyd Ring + polyurethane combination**
- The dynamic seal has a lifespan of ≥ 30,000 lifting cycles
- An external seal wear indicator is provided
#### 5. Intelligent Maintenance Function
- Real-time monitoring of cylinder health status (optional 5G module)
- Preventive maintenance reminder system
- Remote fault diagnosis interface
