To perform this hauling and lowering exercise, you'll be using a descender and fixed back-up device that's been incorporated onto the secondary line of the main system to lower and raise a load off either the ground or a raised platform -- you may also have the option of using a dual main system, ie. utilizing two I'D's instead of an I'D and ASAP.
SPRAT recommends that you use a compatible extension (like a lanyard) between the back-up device and anchorage system so that you can manage the main and fixed back-up systems simultaneously.

During your SPRAT Evaluation, L1 techs will be asked to demonstrate competence lowering and raising a load while using an appropriate descent control device attached to an anchorage system.
You will be standing on either a platform or the ground while completing this exercise. You will not be required to negotiate an edge with the load you're hauling.
Your SPRAT Evaluator will be watching to make sure that you:
- are able to stop and lock off the device.
- properly manage the fixed backup system that is used.
A mechanical advantage system for raising the load will be built integrally with the main ropes. You should understand how the system you're using works, and be able to explain it to your Evaluator if asked.
You may also be asked to establish the main and fixed back-up system you'll be using as part of this exercise.
Although part of the requirement for this exercise is completing it alone, if you're completing your Evaluation at the same time as a L2 and L3 candidate, SPRAT will allow you to work together and turn this requirement into a team exercise -- crossing one requirement off each respective syllabus at the same time.
To do this, you'll demonstrate this hauling and lowering requirement while operating one side of the system used in a cross-haul with and under the instruction of a L2 tech. A L3 candidate will manage the work task being completed, as part of their team scenario requirement, using delegation and communication to ensure the maneuver is completed efficiently and safely (L3's will also need to come up with the rescue plan).
We’ll go into further detail on all of the above during your training week.
Most Common Discrepancies to Avoid:
- You're unable (or forget) to lock off the lowering device.
- The backup system is being operated from a harness and you're attached to the anchorage system (this turns into a fail if you're not attached to the anchorage system).
- An insufficient amount of rope is being used (fail)
