TH-30A Reciprocating High-Rise Escape Descent Control Device 10-100kg Load 0.8-1.3m/s Descending Speed 15m Steel Wire Rope Emergency Fire Evacuation Descender for 3-4 Floors

TH-30A reciprocating high-rise escape descender is a reliable passive emergency evacuation tool for residential buildings, office buildings, hotels and commercial premises in case of fire disasters. It adopts reciprocating working mode to realize continuous cyclic rescue. It supports load range from 10kg to 100kg, suitable for most adults and teenagers. The stable descending speed is controlled between 0.8~1.3 m/s to ensure safe and gentle landing. Standard aviation steel wire rope length is 15m, matching 3-4 floors evacuation, and customized rope lengths are available. The steel rope breaking force exceeds 1000kg to guarantee extreme tensile safety. Supplied as a full set including rope reel, descent control unit, 2 safety harnesses, expansion bolts, auxiliary rope, fixing bracket and safety hook. Easy to install on window frame or wall as permanent emergency standby equipment for high-rise fire escape.

1. Reciprocating Cycle Rescue Design, Continuous Evacuation

   After one person lands safely, the other harness rises automatically. Multiple personnel can escape one after another without manual rope recovery, greatly improving evacuation efficiency during fire emergencies.

2. Wide 10–100kg Load Adaptability

   Effectively accommodates users of different body weights including teenagers and adults. Stable speed control will not cause too fast or too slow descent under varied weight.

3. Constant Speed Control 0.8–1.3 m/s, Comfortable & Safe Landing

   Built-in mechanical speed limiting structure automatically stabilizes descending speed within safe range. Avoid free fall danger and excessive impact when reaching ground, effectively prevent panic injury.

4. High-Strength Aviation Steel Wire Rope, Breaking Force Over 1000kg

   Professional aviation grade steel cable provides huge tensile reserve. Strong resistance to abrasion and breaking, reliable under complex high-rise escape conditions.

5. 15m Standard Length for 3-4 Floors, Custom Length Support

   Standard 15m configuration meets common low-rise high building escape requirements. We accept customized rope lengths to match different floor heights and building demands.

6. Complete Full-Set Accessories, Ready for Installation

   All mounting and escape components are included: two safety harnesses, fixing bracket, expansion bolts, safety hook, rope reel and auxiliary rope. Customers do not need to purchase separate spare parts.

7. Simple Wall / Window Fixed Installation, Long-Term Standby

   The bracket can be firmly installed on balcony wall or window side. The whole set can stay on standby permanently for sudden fire accidents; operation is simple after brief training.

TH-30A reciprocating high-rise escape descender is widely adopted as standard emergency evacuation equipment for civil and commercial buildings. Adopting mature mechanical constant-speed descent technology, the device automatically adjusts resistance according to human weight to maintain stable 0.8~1.3m/s descending speed. It avoids uncontrolled falling risks caused by weight difference.

The core load range covers 10kg to 100kg, meeting the escape needs of most residents. Each descent allows one person, and reciprocating structure enables uninterrupted cyclic rescue, which is very important when many people need to evacuate simultaneously.

Equipped with aviation steel wire rope with breaking force greater than 1000kg, the safety factor is sufficient for emergency escape scenarios. Standard 15m rope is designed for 3~4 storey buildings; if customers have higher floors, various customized lengths can be produced.

Every complete package contains comprehensive accessories including two safety belts, fixing frame, expansion bolts for wall installation, safety hook and rope storage reel. After fixed installation on balcony or window, users only need to wear the safety harness and hook onto the descender to start escape operation quickly in case of fire.

Suitable for families, hotels, office buildings, schools and factory dormitories. It is an effective passive escape solution when stairwells are blocked by smoke and flame during fire accidents.
