Abrégé

An impactor apparatus for use with a rotorcraft, comprises a reeling apparatus adapted to be transported by the rotorcraft, reeling apparatus including at least a spool, an actuation system for rotating a spool in a winding direction, and a brake system for braking a rotation of the drum. A cable is wound onto the spool. An impactor mass is attached to a free end of the cable. A release of the brake system causes a drop of the impactor mass by gravity, from a loaded condition, the actuating system subsequently rotating the spool to wind the cable onto the spool to put the impactor mass in a loaded condition.

CLAIMS 1. An assembly of a rotorcraft and impactor apparatus comprising: a rotorcraft, an impactor mass, a cable extending from the rotorcraft, and an electromagnet at a free end of the cable, the electromagnet operable to magnetically connect the impactor mass thereto, wherein the electromagnet is further operable to drop of the impactor mass by gravity. 2. The assembly according to claim 1, further including a reeling apparatus having a spool, the cable wound onto the spool. 3. The assembly according to claim 2, wherein the reeling apparatus has an actuation system for rotating a spool in a winding direction, and a brake system for braking a rotation of the spool. 4. The assembly according to claim 3, wherein the reeling apparatus includes a clutch unit between the actuation system and the spool. 5. The assembly according to claim 4, wherein the clutch unit includes at least one spring exerting a biasing force between the actuation system and the spool. 6. The assembly according to claim 5, wherein the at least one spring surrounds a shaft of the actuation system, and is between an abutment surface securedto the shaft and a coupler secured to the spool. 7. The assembly according to claim 6, wherein the coupler is a diskinside a cavity of a core of the spool 8. The assembly according to any one of claims 5 to 7, wherein the at least one spring is 19

A dock installation system to facilitate installation of dock platforms comprises one or more inflatable supports configured to be positioning under a dock platform. The inflatable support is sized and shaped to floatingly support the dock platform when suitable inflated. An attachment device for the inflatable support, the attachment device is configured to releasably secure the inflatable support to the dock platform when positioned under same. A method for installing a dock system comprises positioning the inflatable support(s) under a dock platform. The inflatable support is inflated to support the dock platform. The inflated support with the dock platform thereon is displaced to a desired position onto a body of water onto which the dock platform is to be installed, the inflated support floatingly supporting the dock platform. The dock platform is fixed at the desired position. The inflated support is removed.
