When you secure yourself you always gotta think about the fall factors.. So here's a question as example: If a person is 80kg and is secured with a static rope or sling and falls 2 meters. What would the force of the shock from the fall be?

80kg

160kg

500kg

1800kg

As you see in the picture we have a split basket with different lenght of the legs.. This is something we often do when we make as split basket around the gantry crane beams at Oslo Spektrum for example.. Why not use same length legs for this?

If same lenght legs the shackle and the ends of the steel will end up on top of the beam in a squeeze..

If different size legs the top rigger will be confused what goes where when he pulls the thing up

What is the "datum point"

The point in the schedule where we go for a coffee break

The point on the rigging drawing where all the measurements starts from (a kind of zero point). It can often be in the middle of the downstage edge or other practical places, but can be from anywhere.. So when we do the markup the head rigger starts his measurements from this point.

The point in the calender when a pandemic strikes and there's no more work.

Some point the headrigger talks about, but 87% of the riggers doesnt care about as well as looking at the drawings :)

A pulley is helpful sometimes, and a lot of you use the pictured Petzl lock pulley. Here's a few things to think about when using such a lock pulley.. Which ones are true?

Every point is easier to pull with a pulley no matter your positioning, etc.

If you use a lock pulley it might be a pain in the ass to open it if you pull the rope all the way up until the knot stops on the pulley.

If the sideways angle of the entering or exiting part of the rope is large the pulley might not function as it should.

It might take more time and energy attaching a pulley, getting the rope correctly through it, pulling the point and removing the pulley afterwards than just getting the rope down and pulling it up the normal way..

If the rope goes in a straight line or worse through most lock pulleys and ratchet pulleys (not bending over the wheel inside the pulley) the lock- or breaking function might not work.

On pulleys like the pictured Petzl Pro Traxion that can be opened always use a carabiner in both holes when in operation so it cannot be opened accidentally.

A pulley is regarded as personal protection equipment so it has to have the right EN-numbers and be checked every year.

When building a bridle we sometimes have to piece together many pieces of steel to get the right lenght. If for example you want to have a 10 meter leg on the bridle but only have available 1 5m steel, 1 2m steel and 1 3m steel for the leg, how do you build a bridle with those?

Generally the order doesnt matter so you just put them together

Generally you always have the shortest piece of steel at the top of the leg, closest to the basket at the end of the leg.

Most of the time when we are doing chokes we use soft steel, slings, etc.. But sometimes when we use steel and a shackle, like in this illustration, there is a right and wrong way of doing it. Which one of these two is correct or are both correct?

The one to the left.

The one to the right.

Both are correct.

In the illustration above you have the typical floor markings.. Most of the times these are for separating what capacity motor goes where.. What weight capacity of the motor are these markings for?

From left to right on the illustration: 1 ton, 1/2 ton, 1/4 ton, 100kg

From left to right on the illustration: 2 ton, 1/2 ton, 1 ton, 1/4 ton.

From left to right on the illustration: 4 ton, 2 ton, 1 ton, 1/2 ton.

From left to right on the illustration: 2 ton, 1 ton, 1/2 ton, 1/4 ton.

From left to right on the illustration: 2000kg, 1000kg, 500kg, 250 kg.

From left to right on the illustration: 1 ton, 1/2 ton, 1/4 ton, 2 ton.
