Toy Crane for EMMA by vandragon_de

thingiverse

This is an accessory to the "EMMA - a Maersk ship" created by vandragon_de on Thingiverse. https://www.thingiverse.com/thing:3142367 The crane has two distinct features, one raises and lowers the container gripper while the other slides the trolley along the crane arm. When mounted correctly, these functions operate independently. There are two versions of the gripper available - one that fits original containers and another with four holes. The version with holes can be used to create a compact design, simply use it as a template, drill corresponding holes in the containers, then insert four M2 screws into the gripper extending a few millimeters below its surface. This allows the gripper with screws to sit atop the containers without requiring any additional clearance. Note: To prevent cable lines from slipping on the wheels, ensure numerous turns around the wheels are made. Alternatively, increase friction by making small cuts in the grooves' surface using something sharp, or employ a rough sandpaper for this purpose.
