Interesting things found or to look for.

June 2015 - In the last few days it has come to my attention that a Worksafe inspector has threatened to shut down one of my clients because the pass certificate wasn't an alloy plate fixed to the side of the hauler, which meant he needed to climb up to the cab to look at the certificate. Here is an extract from 'The Best Practices Guidelines for Maintenance Inspections of yarder Towers' which is what inspectors work to.

Page 28 states - Once the Yarder Tower achieves the industry standard (ie: it passes), an inspection certificate (label, plate, sticker) will be issued by the tower inspector.

I have been in touch with Worksafe about this and when I get a result to this enquiry, I will post to this website.

Personally, I think they are way out of line!

December 2014 - Recently I had the opportunity to check out the CDL grapples at Holster Engineering in Tokoroa it is an impressive high speed high pressure grapple built tough and all made in thier workshop. They also have a full replacement parts store so minimum down time getting spares. If you are looking to upgrade your grapple these units are definitely worth a look -  they have two models to choose from, just go to the link page and click on the Holster Engineering or CDL Grapples link or phone +64 7 886 7179 or 027 324 9091 ask for Marty or Bruce.

October 2014 -  Please note that Active Equipment in Rotorua now has new shackles in stock, something to consider if you have original shackles on older machines. These shackles are the manufacturers spec guy block shackles.

17.10.13 - Recently there was an incident resulting in a badly damaged tower on a Madill 071. It was caused by a bow shackle securing the guy block to the top of the tower breaking  while pulling in a drag. The shackles had been checked only months before and looking at the broken parts there appears to be no indication of fatigue, i.e. visual cracks. There is no indication or record of how old they are and there is no time limit on replacing them unlike guy ropes, so if you have shackles that secure guy blocks or ropes and you think they are original or you have no idea how old they are, it may be a good idea to change them and note the date in your Hauler log book. Although this was a non injury accident it was expensive both in repair and down time.

27.8.13 - There seems to be confusion out there concerning FOPS and OPS certification for the operators cab on all haulers. As it stands in the 'Approved Code of Practice for Safety and Health in Forest Operations', Cable harvesting 14.8.4 states, "All yarders shall have certified Falling Object Protective Structures (FOPS) and Operator Protective Structures (OPS) on their cabs. "An OSH requirement. That doesn't mean new cabs; it means the bars on the windows shall comply to that standard.

In the 'Best Practice Guidlines for Inspections of Yarder Towers 'there is no mention of cabs. The latest copy I can find was revised in September 05 and approved by the Dep of Labour; although common sense suggests cabs should be as per manufacturers specification, and be sound and secure. The problem is, as happened recently, after a successful inspection and a pass was issued some three months later an OSH inspector paid the crew a visit and threatened to shut down their operation because the cab cert for FOPS and OPS was out of date and, in his opinion, the hauler should not have passed. When asked he was totally unfamiliar with the guidelines. As it stands a tower inspector, like me cannot fail an inspection just because a cab cert is out of date or it does not have one at all. At the moment I am trying to get clarification as to whether this should ,or should not be included in our inspection. I will let you know what happens.

19.03.13 - Please take note - deadman ropes must now comply with common guy rope 7yrs for a pole yarder and 5yrs for a swing yarder. Ferrules should be date stamped or if spliced a rope record should be kept with the hauler. No old ropes will be acceptable. Its the old saying 'a guy rope is only as strong as its weakest link! ' and you all know what happens when a guy lets go.

Madill 171 skyline fairlead assembley ripped off due to logging outside 45 deg causing shearing effect by guy anchor ring.

We have had another report of a 171 skyline fairlead assembley failure, all owners of Madill 171 haulers should check for cracks in the pole under the guy ring  just below the fairlead assembley.

Bow shackles that connect guy ropes to pole or extensions for cracks.  

Short strops that connect guy blocks to pole on TY90 pull through ferruls. 

Cracks on gantry frame below guy winch drums common on Madill 120.

Operator manuals are available for Madill and Thunderbird Haulers. Contact Active equipment through the link on the 'links' page.
