The reasonable shape of the alley is to make the structure in a good stress state under different formation pressure conditions. It can ensure the safety of the roadway and the most economical materials, and at the same time, the section excavation works are the least and easy to construct. It is now generally considered that an elliptical arch is a reasonable shape of a roadway, followed by an arc arch.

Load:60-10,000kg
The state of
the art VR type electric chain hoist is an indispensable item used in the
light-duty lifting industries across the world, where the characteristic of
reliability is designed into the hoist structure, safety features incorporated
into the operating system, and advanced crafting techniques introduced into the
modern design.
Made for less
volume, lighter weight, and more operating safety and convenience, the chain
hoist has the ability to adapt to various working environment, all available at
a competitive price. Different models offer choices of lifting capacities ranging
between 60kg and 7500kg to suit everyday light-duty lifting work. When used in
combination with manually operated trolley, hand-pushed trolley, or
motor-driven trolley, the hoist can be mounted on the mono-rail traveling
Crane, Jib Crane, and Gantry Crane. This provides a maximum solution to solve
your material handling applications.
