Since the hoistway-type construction elevator runs in the hoistway,
the surrounding is protected by the hoistway, and at the same time,
the counterweight-traction machine is used as the power, which
fundamentally solves the risk of falling, topping and tipping.
A large number of automatic control is used, which reduces the risk
of manual operation and greatly improves the convenience; the
lifting speed of 120 m/min is three times that of the external
hanging elevator, and the transportation in and out of the material
truck is more convenient.
There is no need for additional protection, no need to build
channels and foundations, and no need to reserve or fill the feed
inlet, which greatly shortens the construction period and saves
