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.

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.
