Semi-Automatic Hand-Crank Bollard BS-SS602A
Semi-automatic 304 stainless steel bollard with hand-crank raising, automatic lowering, 600mm height and 219mm diameter for low-frequency vehicle access.
Description
Semi-Automatic Hand-Crank Bollard BS-SS602A
BS-SS602A is a mechanically operated semi-automatic bollard for vehicle-access points with relatively low operating frequency. The column is raised by hand crank and lowered manually, allowing the project to avoid a powered drive system where that operating method is suitable.
Functional Features
- Mechanical operating structure without a powered lifting drive.
- Hand-cranked ascent and manual descent.
- Reflective warning film improves column visibility.
- Suitable for access points where operating frequency and staffing permit manual control.
Technical Parameters
| Warning device | Reflective film |
|---|---|
| Ascending time | Approximately 15–20 seconds, depending on hand-crank speed |
| Descent time | Less than 4 seconds |
| Column material | 304 stainless steel |
| Base housing panel | 304 stainless steel |
| Base housing | Q235 with anti-corrosion surface treatment |
| Column wall thickness | 6 or 8 mm (±0.5 mm) |
| Rising height | 600 mm |
| Column diameter | 219 mm (±0.5 mm) |
| Operating temperature | -30°C to +55°C |
Suitable Project Applications
- Residential compounds and property-management entrances
- Commercial or institutional access points with low vehicle frequency
- Restricted parking areas where manual operation is acceptable
Selection and Site Checklist
- Confirm required column height, diameter, wall thickness and surface finish.
- Review vehicle frequency and confirm that manual operation is practical.
- Check underground space, foundation dimensions and local drainage conditions.
- Confirm bollard spacing, visibility and the intended traffic-control procedure.
- Have the installer review emergency access and applicable local safety requirements.
