TWZ180D Tunneling Trolley 1、Main Applications Asa special equipment developed for underground excavation of subway tunnelprojects, this product is suitable for the operations under soft soil, sandygravel, and decomposed rock stratums.
Itincorporates the earthwork excavation, trenching, small duct drilling, rockcrushing, auxiliary support, and deslagging functions.
It’smainly suitable for the excavation of pilot tunnels and stations in size of 4m×4m.This equipment is equipped with external power supply, hydraulic drive, and crawlerchassis traveling system.
Featuringhigh efficiency and environmental-friendliness, compact structure, and highmobility and flexibility, this product can effectively substitute the manualoperations and remarkably improve the working efficiency.
2、Technical Features Highsafety and reliability: The working device is optimized by finite elementanalysis and its structure and hinge points are reasonably arranged to ensurehigh reliability.
Highefficiency and energy-saving: The completely imported load-sensing variabledisplacement pump is applied to realize the on-demand supply of hydraulic oilflow, save the energy, and reduce the system heat.
Sufficientpower: The imported three-phase AC motor and high-horsepower hydraulic drivemotor are applied to realize low start surge current, high drive force, andstrong gradeability.
Comfortableoperations: The integrated electro-hydraulic proportional pilot control systemrealizes the accurate control and smoother operations of working device. Therearview camera and the shock-absorbing leather seat are installed to provide amore comfortable operating experience for the operator.
Remotecontrol: The right boom adopts the electronic control technology, which canrealize remote control, to promote the positioning accuracy and improve theworking efficiency.
