I. Product Overview
The multi-functional emergency rescue excavator is suitable for emergency rescue operations during natural disasters that require high-intensity and long-duration work. The equipment itself is equipped with a quick-change coupler, an ultra-long sight distance wireless remote control system, and a reinforced bucket, and it has extremely strong adaptability to high altitudes and low temperatures. On the basis of retaining the various advantages of traditional excavators, a remote control operation mode has been newly added, effectively ensuring the safety of rescue workers' lives. It can play a role in emergency rescue road clearance, river channel dredging, blockage and breach repair of barrier lakes, and post-disaster reconstruction.
II. Scope of Application
- Used for handling dangerous situations such as dike cracks, leaks, landslides, breaches, or river blockages
- Most suitable for construction operations at altitudes above 4000 meters
- Suitable for water area management and river channel desilting
- Suitable for emergency rescue operations in wetlands and swamps
- Suitable for embankment reinforcement before, during, and after disasters
III. Product Features
(1) Ultra-sight-distance remote control operationIt enables remote control operation of all actions and is applicable to work in earthquake relief, dangerous and explosive, and toxic environments. The remote control operation distance is ≥ 2000m.
(2) Multiple operation control modesThe excavator has multiple operation modes such as local manual operation, short-range remote control, and long-range remote control. The operation mode in the remote control cabin is the same as that inside the excavator. The operation cabin is a closed cockpit, and the display screen has functions such as video display, real-time 3D attitude display of the excavator, and display of work information and alarm information.
(3) All-weather remote wake-up functionThe all-weather remote wake-up function supports functions such as one-key power on/off, starting, and shutting down of the excavator through remote control throughout the day.
(4) Strong environmental adaptabilityThis equipment has extremely strong adaptability to high altitudes and low temperatures and can play a huge role in emergency rescue work such as mountain rescue and landslides.
(5) Provide multiple open and mobile simulated remote control consolesThe operation cabin is a closed cockpit, and the display screen has functions such as video display, real-time 3D attitude display of the excavator, and display of work information and alarm information.
(6) High-integration detectionIt can measure 4 kinds of gases (specifically: CO2, CH4, CO, H2S)
(7) Cloud platformThe equipment cloud management platform can remotely monitor the operation information and power level of the equipment, as well as the parameters of the on-site toxic and harmful environment, and conduct comprehensive management and application to ensure the timeliness of the equipment.
(8) Multiple hydraulic output power interfacesAn ultra-high pressure output interface is reserved, and the output hydraulic parameters are as follows: two ultra-high pressure outputs, with a pressure of 72MPa; an ultra-high pressure flow rate of 0.7L/min; a low pressure flow rate of 4L/min; the two ultra-high pressure outputs are used independently of each other without affecting each other.
