TWZ260D Tunneling Trolley
1、Main Applications
As
a special equipment developed for underground excavation of subway tunnel
projects, this product is suitable for the operations under soft soil, sandy
gravel, and decomposed rock stratums.
It
incorporates the earthwork excavation, trenching, small duct drilling, rock
crushing, auxiliary support, and deslagging functions.
It’s
mainly suitable for the excavation of pilot tunnels and stations in size of
6m×6m. This equipment is equipped with external power supply, hydraulic drive,
and crawler chassis traveling system.
Featuring
high efficiency and environmental-friendliness, compact structure, and high
mobility and flexibility, this product can effectively substitute the manual
operations and remarkably improve the working efficiency.
2、Technical Features
High
safety and reliability: The working device is optimized by finite element
analysis and its structure and hinge points are reasonably arranged to ensure
high reliability.
High
efficiency and energy-saving: The completely imported load-sensing variable
displacement pump is applied to realize the on-demand supply of hydraulic oil
flow, save the energy, and reduce the system heat.
Sufficient
power: The imported three-phase AC motor and high-horsepower hydraulic drive
motor are applied to realize low start surge current, high drive force, and
strong gradeability.
Comfortable
operations: The integrated electro-hydraulic proportional pilot control system
realizes the accurate control and smoother operations of working device. The
rearview camera and the shock-absorbing leather seat are installed to provide a
more comfortable operating experience for the operator.
Remote
control: The right boom adopts the electronic control technology, which can
realize remote control, to promote the positioning accuracy and improve the
working efficiency.
