Specification of spiral-conveyer for logistics warehousing
distribution center
1 Scope
This Standard specifies the technical requirements, test methods, inspection rules,
marking, packaging, transportation and storage of spiral-conveyers.
This Standard applies to spiral-conveyers (hereinafter referred to as “conveyors”) that
are used indoors such as logistics warehousing distribution centers, to continuously and
automatically convey box-type items in the vertical direction. Spiral-conveyers for
conveying other types of items may also refer to this Standard.

3 Technical requirements
3.1 Basic requirements
3.1.1 Working environment conditions
The working environment conditions of conveyors shall meet the following
requirements:
a) Ambient temperature: -5 °C ~ 40 °C;
b) Relative humidity: the relative humidity shall not exceed 50 % at a temperature
of 40 °C; the relative humidity can be appropriately increased when the
temperature is low, but it shall not exceed 85 % and shall not condense;
c) Altitude: not more than 1000 m;
d) The power supply of conveyors is three-phase AC, the frequency is 50 Hz, the
voltage is 380 V, the allowable deviation of the peak current to the frequency
fluctuation is ±1 Hz, and the allowable deviation of the voltage fluctuation is
±10 %.
NOTE: When the above working conditions are exceeded, it shall be resolved through negotiation
between the user and the manufacturer.
3.1.2 Requirements for boxed items
The box-type items handled by conveyors shall meet the following requirements:
a) The mass of the item shall not be greater than 50 kg;
b) Specifications and dimensions: length (350 mm ~ 900 mm) × width (150 mm ~
500 mm) × height (50 mm ~ 500 mm);
c) Maximum bearing capacity: 50 kg/m.
3.2 Main structure
The main structure of conveyors is shown in Figure 1.
3.4.4 When the conveyor is working under full load, the upper frame and driving parts
shall be stable and reliable, and there shall be no obvious vibration when the motor is
running.
3.4.5 Pre-tightening force shall be applied to the chain transmission part. The pre-
tightening force shall be able to prevent the chain from slipping off or jamming from
the sprocket.
3.4.6 The chain plate shall be injection-molded with engineering plastics, with a smooth
surface and no obvious defects such as pores and shrinkage.
3.4.7 The material of the chain plate shall have sufficient flexibility, and shall not be
easily worn or broken when conveying box-type items that meet the specifications of
3.1.2.
3.4.8 The tensioning mechanism shall be convenient for manual adjustment or
automatically realize the tension compensation of the chain.
3.4.9 The spiral angle shall generally not be greater than 15°, and it shall ensure that the
conveyed items will not overturn during the conveying process.
3.4.10 The friction coefficient of the chain plate shall ensure that the items will not slide
down during the conveying process.
3.5 Surface coating
3.5.1 All steel surfaces that need to be painted shall be pre-treated, and shall reach Grade
Sa21/2 in GB/T 8923.1-2011. Manual rust removal shall meet the requirements of
Grade St2. It shall also remove burrs, oxide scales, welding slag, oil pollution, etc.
3.5.2 The spray-painted or plastic-sprayed surface shall be smooth and uniform, with
the same color and luster. The paint film or plastic coating shall be firmly attached.
3.5.3 The adhesion of the paint film shall meet the requirements of Grade 2 specified
in GB/T 9286-1998.
3.5.4 All the untreated exposed surfaces of the mating steel parts shall be coated with
anti-rust grease.
3.6 Performance requirements
3.6.1 Conveyors shall be able to work normally under the condition of carrying the
rated load. The main structural parts of conveyors shall be able to withstand 1.25 times
the rated load. The equipment shall have an overload protection alarm function when
the rated load is exceeded.
3.6.2 Conveyors shall adopt a gentle start mode to ensure smooth start without impact
and facilitate maintenance and adjustment.
3.6.3 The control system of conveyors shall be able to monitor the running status of
conveyors, and have the functions of fault detection and alarm.
3.6.4 The conveying capacity of conveyors shall not be lower than the design value.
3.6.5 The failure-free rate of conveyors shall not be less than 97 %.
3.7 Noise
The sound pressure level noise of conveyors during load operation shall not be greater
than 85 dB(A).
3.8 Safety requirements
3.8.1 The electrical safety requirements of conveyors shall comply with the relevant
provisions of GB 5226.1.
3.8.2 The metal structure of conveyors and the metal casings and metal pipe grooves of
all electrical equipment shall be reliably grounded. The grounding resistance shall not
be greater than 4 Ω.
3.8.3 The insulation resistance of conveyors shall not be less than 1 MΩ.
3.8.4 The control circuit shall have interlocking and protection functions, including:
