Rigging & Weight Handling Basics 3-Day
COURSE LENGTH: 3 DAYS (24 HOURS)
COURSE LOCATIONS: CITY
Train and assess personnel as weight handling professionals. Trainees will be given a series of scenarios in which they will have to estimate the weight of loads, determine the center of gravity, determine expected stresses and select the required rigging gear with sufficient capacities for the loads.
Trainee must prepare various loads for lifting, utilizing the correct knot(s) for securing and lashing, and then safely moving and landing the loads over a horizontal distance. They will move the loads through areas with minimal clearance and will adjust the loads to transition from horizontal to vertical.

FUNCTIONS – Trainees will use beam clamps, holdbacks, chafing material, and chain hoists to raise, lower, and drift loads (pumps, motors, valves, etc.) through the mock-up area simulating actual shipboard conditions. Each will take turns being the Rigger in Charge (RIC).
During these evolutions, trainees will give maneuvering directions using hands signals as the others give call backs and perform the actions required to accomplish each direction (i.e. Hoist up, Stop, Hoist Down Easy, etc.) Finally the loads will be palletized and secured for transportation utilizing a truckers hitch and/or various other knots to ensure adequate and confident securing.

DUTIES & RESPONSIBILITIES
Weight Handling Terms and Responsibilities – Understand the terms and responsibilities of weight handling.
Stability and Load Dynamics: Lifting, Moving, and Landing a Load – Recognize the Center of Gravity, understand when that is found the load will be stable.
Determining Weight, Center of Gravity, and Load Stress – Always remember to know the weight of the load before you start any rigging evolution.
Inspection, Selection, and Use of Rigging Gear – Select the appropriate gear based on the wight of the load.
Basic Knots – Learn each knot, when to apply it, and understand why that knot is being used. Ability to show each knot being tied per request.
Crane Commumications and Signals – Learn and understand how to use each hand signal. Ability to show each hand signal per request.
Cane and Rigging Accidents – Know what is characterized as a crane and rigging accident.
Operational Risk Management – Understand that being attentive during any rigging evolution will help the team be safe.
Dry Docking – Learn the terms used during a docking/undocking.
Performance Review Evaluate for Remediation – Apply what has been taught throughout the course. Complete the job given in a safe manner.
