A.1 General conditions for using the construction hoist
General conditions for using the construction hoist has described all conditions stated in such relevant parts of
this manual as Chapter C “Overview and technical characteristic”, Chapter D “Basic setup” and Chapter E “Mast tie
and tie-in”. Please consult with our company for those conditions that are not stipulated.
Some particularly important situations about operation of construction hoist will be described again by illustration
in relevant parts of this manual.
A.1.1 Climate and geographical conditions
A.1.1.1 Wind
The using conditions of the construction hoist, such as standard height, counter-force and pressure under the
base mat, are relying on standard wind speed at the location of the construction hoist.
Standard wind speed (GB50009. 2001) is the average wind speed tested in the place that is 10 meters above the
flat ground for successive 10 minutes.
A.1.1.2General conditions
The standard wind speed during the operation of the construction hoist should use the average wind speed
diagram of the located country to determine the standard wind speed area.
Please consult with our company for different standard wind speed areas of other nations or areas except China.
A.1.1.3 Special conditions, such as:
ƔNo average wind speed diagram;
ƔThere are special stipulations or some other situations in the located country or area;
ƔThe altitude is higher than that marked in the average wind speed diagram;
ƔBasin, defile, mountain pass, hills, etc.
Ask users to design in advance to determine the standard average wind speed at the installation location of the
construction hoist. Users can also consult with our company and provide relevant data.
A 1.1.4 Operation of construction hoist
The construction hoist can only be operated where the maximum wind speed is less than 72km/h.
A.1.1.5 Installation, dismantling and location changing of the construction hoist
Installation, dismantling and location changing of the construction hoist can only be conducted when the
maximum wind speed (gust of wind) is less than 45km/h.
A.1.1.6 The environmental air temperature tested in the shady place
The temperature is one that is tested within a non-hermetic and wind &rain-proof cover that is 2 meters above
