IMPACT RATED LOWERING BOLLARDS

OVERVIEW:

We offer two types of lowering bollard and these are tested at 80kph (50mph) to the PAS68 and ASTM Standards These particular bollards were the best performers during these tests of all manufacturers. They are to be used to prevent forcible vehicle attack on high security areas.

USE:

Impact rated bollards of the lowering type are highly effective in preventing forcible vehicle attack on high security sites of national and international strategic importance. Nuclear sites, cash centres, airports, embassies are typical users of this product.

SIZE:

The bollard height is 1m above ground and the core diameter 300mm. Overall diameter in stainless steel finish 323mm and in black polyurethane 350mm diameter. The base unit is 1.8m deep below finished ground level. Bollards should be set at maximum 1.5m centres.

CONSTRUCTION:

The circular bollard is raised and lowered hydraulically with the ram being inside the bollard. The bollards retract into a below ground casing and link to the hydraulic drive unit which is remotely located above ground in a lockable steel cabinet. Bollards capable of resisting 100KN axle loading when lowered.

FINISH:

Steel core with stainless steel shroud. Alternatively black polyurethane sleeve. All other exposed steel surfaces hot dipped galvanised.

DRIVE:

Each individual bollard has its own drive unit housed in freestanding cabinet to ensure each bollard operates at the same speed. Drive is electro-hydraulic with high pressure pump, electric motor, and all necessary valves. Each drive unit has release valve for emergency lowering and hand operated lever for raising in event of power failure. Drive unit can also include if required oil accumulators for operation without power, the size depending on the number of operations required. Speed of operation average 6.5 seconds up and down. Operating temperature range -15 to +40. For cold environments additional heating is required and available.

POWER SUPPLY:

Three phase 240/415v 1.5kw minimum. Steel wire armoured cables, the number of cores depending on control function. Wiring to IP55 standard.

OPTIONAL SAFETY EQUIPMENT:

- Traffic lights, red/green 200mm diameter in freestanding post.
- Below ground vehicle detection loops.
- Electronic eye beam
- Traffic lights, red/green 200mm diameter in freestanding post.
- Below ground vehicle detection loops.
- Electronic eye beam

CONTROL FUNCTIONS:

- Key switch in gatehouse, on post or remote.
- Card reader – swipe – proximity in freestanding post
- Intercom linked to handset in freestanding post
- Below ground vehicle detection loops for automatic raising on entry/exit with timer.
- Automatic link to fire alarm system.

INSTALLATION:

Bollards fixed to reinforced concrete base by expansion bolts. Drainage and power supply ducts connected and concrete filled to finished ground level. This is the dramatic result of the test on high security bollard, no distortion and immediately reusable.
