Suspended load guidance is not a single action. During one lifting operation, a rigger may do several different things with the load: let it travel freely, apply a small orientation correction, prevent it from contacting nearby equipment, assist the final landing, or simply watch without touching it at all.
Each of these activities is different in purpose, method and the type of engineered control it requires. Yet most lifting procedures treat them as a single undifferentiated task: "guide the load."
The RiggerSafe® Guidebook establishes six distinct engineering objectives that cover everything a rigger does — or avoids doing — during the guidance phase of a lift. Understanding which objective applies at any moment of the lift is the starting point for selecting the right guidance method.
Why Objectives Matter
The guidance objective determines three things:
- What type of engineered control interface is required — a rigid interface for precise positional corrections; a flexible tensile interface for travel and drift control
- Where the working position should be — the rigger's location changes depending on what they need to achieve
- How much input is required — precise placement requires minimal force; preventing contact with nearby pipework may require more sustained directional influence
A rigger applying heavy lateral force when only a minor orientation correction is needed will overcorrect the load and create new movement. A rigger using a flexible tensile line when a precise final placement is required will not have the directional control to achieve it.
Identifying the correct objective before applying input is the engineering discipline that separates planned guidance from improvised guidance.
Objective 1: Maintain Orientation
Some loads naturally rotate as lifting begins. The load geometry, the rigging arrangement, a slight imbalance in the CoG, or stored twist in the slings can all initiate rotation that — left unchecked — makes final positioning significantly more difficult.
Maintaining orientation does not mean preventing all movement. The objective is to keep the load in an orientation that is suitable for the next stage of the lift — not necessarily perfectly aligned throughout travel.
Typical loads: fabricated frames, structural members, pumps, valves, electrical panels, machine assemblies
Guidance characteristic needed: Early-stage intervention; moderate input; the rigger accompanies the load without constraining its natural movement more than necessary
Interface requirement: Rigid interface, applied early and gently. The goal is to stop rotation from developing, not to correct heavy rotation once it has already built up.
Objective 2: Prevent Contact
As loads travel through busy plants, fabrication yards and confined areas, they often pass close to existing structures, equipment, pipework, or other machinery. The guidance objective is to maintain safe clearance between the load and the obstacle.
The correction required for this objective is often very small — a light lateral input to nudge the load a few centimetres away from a potential contact point. The consequence of failing to make that correction may be significant: damage to process pipework, electrical equipment, or instrumentation, in addition to the risk of unexpected load movement caused by the contact itself.
Typical context: Travel through congested plant areas; passage close to pipework, switchgear, or fragile equipment
Guidance characteristic needed: Light, sustained directional input; the rigger needs to maintain separation throughout the travel path, not apply a single correction
Interface requirement: Rigid interface for directional control; working length sufficient to maintain the rigger's working position away from the movement envelope
Objective 3: Position the Load
Occasionally a load travels correctly to its destination but needs to be moved laterally or rotationally into a specific location within the landing zone. The landing point may be a precise structural location, a machine mount with alignment features, or a position defined by survey marks on the structure.
This objective requires the most precision of the six — the tolerance is determined by the engineering of the installation, not by the rigger's judgement of "close enough."
Typical loads: Structural members to exact grid positions; equipment skids over mounting holes; components requiring alignment with existing structure
Guidance characteristic needed: Precise, controlled input; the rigger needs to be able to judge small movements and stop input the moment the load has reached the correct position
Interface requirement: Rigid interface; moderate working length to maintain separation while allowing fine positional control
Objective 4: Correct Rotation
If orientation has been lost during travel — or if the load's rigging arrangement produces rotation under load that was not anticipated during planning — the rigger may need to correct a rotating load before it can be positioned or landed.
This is one of the most technically demanding guidance objectives. A rotating load is already in motion. Applying force to stop it requires the rigger to understand that the force must oppose the rotation, not match it — and that the load's inertia means the correction takes time to take effect. Applying too much force, or force for too long, creates counter-rotation.
Guidance characteristic needed: Precise, phased input; apply, observe, adjust; the minimum effective input, not the maximum available force
Interface requirement: Rigid interface is essential for this objective. A flexible tensile interface can only pull — it cannot apply the lateral or torsional input needed to correct rotation effectively.
Objective 5: Final Placement
The final placement objective covers the positioning of the load at its landing point — the last stage of the lift. This is the highest-risk objective of the six, because it combines the greatest precision requirement with the highest hand exposure risk.
Final placement may require the load to be lowered over guide pins, landed on structural seatings, aligned with existing flanges, or positioned over anchor bolts. All of these tasks have tight tolerances. All of them occur with the load close to the landing surface, where closing hazards are present.
Guidance characteristic needed: Fine positional control; sustained attention; readiness to stop if conditions are not correct
Interface requirement: Rigid interface of the appropriate working length to allow the rigger to guide the load from outside the closing hazard zone. The working length must allow the rigger's body to remain clear of the space between the load and the landing surface.
Objective 6: Do Nothing
This objective is as important as any of the others — and it is the one most commonly overlooked in guidance planning.
Professional riggers do not guide suspended loads continuously. They observe the load's behaviour, monitor its path and movement, and intervene only when the lift requires it. The default during travel, during settling, and when the load is moving correctly without influence, is to apply no input.
Unnecessary input — touching the load when it does not require guidance — introduces new forces and new movement. The instinct to maintain contact with the load during travel is understandable, but it works against stable movement. The guidance objective during free travel is to watch, not to touch.
Understanding that "do nothing" is a valid and defined engineering objective changes how lifting teams approach the guidance phase. Not every moment of the lift requires an action. Some of the most important moments require only observation and readiness.
Objective → Interface → Position
The six objectives create a clear decision sequence:
- What is the guidance objective for this stage of the lift?
- What engineering characteristic does that objective require?
- What type of interface delivers that characteristic?
- What working length allows the rigger to apply the interface from the correct working position?
This sequence — objective first, interface second, position third — is how the RiggerSafe® Engineering Method™ approaches every phase of every lift. The guidance action is determined by the engineering requirement of the task, not by habit, availability or what was used on the last job.
