FIELD: physics.
SUBSTANCE: device includes load device, anchor device for connection to building constructions, device for hanging to crane load gripper, test effort gauge. Load device is made in the form of jack and different arm lever connected to anchor device. One lever end is connected to jack rod by mobile joint, the other end is connected to test effort gauge attached to load gripper by hanging device. Anchor device is made in the form of beam attached to building columns. Device can be equipped with threaded unit for tension of tested crane cable.
EFFECT: enhanced reliability and operation safety, reduced labour cost of crane tests in restricted conditions.
