Meets AS4772-2008 Standards? Yes.
Complicant to future standards? Yes. Independent Government testing has passed the Tefra design to meet or exceed the proposed International ISO Standard.
Automatically locked into position? Yes. Front hooks closes first, then rear hook. Pins will be held firmly, even with slight variance in bucket pin centres.
Dual Lock Design? Yes. If the hydraulics fail, both pins remain locked into position. The bucket cannot swing on one pin.
Mechanical & Positive Safety System? Yes, see Safety Locking Mechanisms below.
Multiple Safety Locking Mechanisms?
1. Primary is Hydraulic activation.
2. Secondary is hook shape, where the geometry of the pick up forces the hooks to stay closed.
3. Third is Active Protection System consisting of two separate powerful springs that apply pressure to the hooks.
What happens if hydraulics fail? In an event of the hydraulic failing, the bucket stays on both pins through the safety systems, however, the bucket will have some movement on the pins to provide indication of failure to the operator.
Detach Sequence? Yes. The Smart Valve system does not allow the bucket to detached unless in the fully crowded in position.
What is a Smart Valve? A Smart Valve is a simple float device that prevents Hydraulic Oil from flowing to the cylinder unless the hitch is in the fully crowded in position.
Can the bucket become detached whilst digging? No. The operator must intentionally go through the re-lease sequence within the permitted release zone.

Our industry is being badly let down by the lack of planning in infrastructure development. Look no further than the lack of planning regarding easing congestion around Brisbane. In 2009, plans were drawn for a $7 billion Cross River Rail (CRR). Upon change in Government in 2012, this was scrapped and replaced with Brisbane’s Bus […]

The large retailers and restaurant chains were pretty much the only options.
