What is a hoisting plan?
The lifting plan organizes a lifting operation from its preparation to the stable placement of the load. It must specify what will be moved, where, with what equipment, and under what conditions. It is not merely a signed permit or a description of the equipment: it details the load, the maneuver, the environment, and the roles of the personnel involved.
The level of detail required depends on the complexity. A well-defined, repetitive operation can rely on a procedure valid for its conditions, while a unique maneuver requires a specific analysis. In both cases, it must be verified that the actual situation matches the plan. The fact that a lift has been performed before does not guarantee that a change in load, support, or route will be safe.
Understanding the load and its securing
Planning requires reliable information on the load’s mass, dimensions, center of gravity, and lifting points. Relevant uncertainties must be resolved before selecting the maneuver. A visual estimate of weight may be insufficient, especially if there are internal components, fluids, removable parts, or modifications that alter the available data.
Accessories are selected based on the load, attachment points, hook, and lashing configuration. Angles, compatibility, edges, and other conditions that affect capacity or integrity must be considered. The capacity of an assembly cannot be determined simply by adding the figures of its components. The corresponding instructions and technical data must govern selection and use.
Choosing equipment and configuration
Cranes and lifting equipment have capacities that depend on their configuration. Planning must consider the radius, position, installed accessories, and the conditions specified by the manufacturer. A machine’s maximum rated load does not necessarily represent its capacity at the most unfavorable point of the planned travel.
Stability and supports must also be verified. The ground, nearby structures, excavations, and buried utilities can all influence the location. When specific strength data or calculations are needed, they must be obtained from qualified personnel. A plan cannot assume the support capacity is sufficient simply because the surface appears firm or because other equipment has operated there previously.
Route, environment and interferences
The route must include the initial position, the movement, and the final placement, with enough space to maneuver and safely remove accessories. Collisions, entrapments, and exposure to suspended loads must be controlled. Power lines, structures, traffic, and other operations that may enter the area of influence of the equipment or load must also be considered.
Business coordination is necessary when several companies are involved or the operation affects their work. Access control and communication must be maintained throughout the operation. Weather conditions are assessed according to the equipment and load: it is not advisable to set a universal wind threshold that ignores the exposed surface area, configuration, or applicable instructions.
Functions, communication and supervision
The plan must identify who prepares and validates the operation, who directs or supervises it, who operates the equipment, and who performs the coupling and signaling when applicable. Personnel must be competent for their roles. If the operator cannot observe the entire route, the necessary signaling equipment and personnel must be designated to guide them safely.
Communication must be unambiguous and include a pre-established response for loss of contact, doubt, or unforeseen circumstances. Any significant change should trigger a review of the operation. Time constraints do not allow for replacing a necessary function with improvised instructions from multiple people simultaneously, nor for continuing when those involved do not share the same interpretation of what needs to be done.
Practical example
A company needs to install an air conditioning unit on a roof. Before contracting the work, they confirm the weight and lifting points using the equipment documentation. The planning team reviews the crane configuration, the radius of travel, the supports, and the capacity of the receiving area. They also identify nearby pedestrian traffic and electrical installations.
The responsible team agrees on the area closure, communication protocols, and acceptable weather conditions. Upon arrival, they discover a recent excavation next to a planned support structure and postpone the start of the work until the location and its capacity are reviewed. This example demonstrates that a useful plan allows for recognizing when conditions have changed; it is not merely a justification for an operation already decided upon.
Pre-checks and change management
Before starting, equipment, accessories, relevant documentation, and site conditions must be verified according to the planned scope. Equipment inspections and usage checks serve complementary purposes. A satisfactory periodic record does not eliminate the need to identify damage, configuration errors, or changes made after that review.
The operation must include designated stopping procedures and a method for resolving incidents without endangering personnel. Changes in load, equipment, position, or route may require recalculating and revising the plan. Upon completion, the load must be stable before removing the securing device, and any incidents observed should be incorporated into the training for future comparable maneuvers.
Spanish framework and limits of the document
Royal Decree 1215/1997 requires that lifting operations be properly planned, supervised, and executed to protect people. It also requires a coordination procedure when several items of lifting equipment simultaneously lift the same non-guided load. The documentation format must allow compliance with these obligations and any applicable specific requirements.
The plan does not replace the lifting equipment’s rated capacities, the manufacturer’s instructions, or the competence of those involved. Nor does it make an operation that is incompatible with its limits acceptable simply because it has been approved. Its function is to define verifiable conditions, coordinate resources, and prevent improvisation. Safety depends on maintaining these conditions during execution and reviewing any relevant deviations.
