A crane risk logic apparatus and system and method for use of the same are disclosed. In one embodiment of the crane risk logic apparatus, the crane risk logic apparatus is integral with a crane, such as a mobile or crawler crane or a tower crane, and located in communication with a load moment indicator. The crane risk logic apparatus receives crane data from the load moment indicator and determines various data analytics, such as, lift angle data, allowable capacity data, operator override data, anti-two-block activation data, operational time data, lift cycle count data, lift classification data, slewing speed data, wind speed data, warning message data, error message data, and winch direction and speed data for each crane lift cycle. The data analytics may be utilized to inform a crane operator evaluation or a crane maintenance schedule for the crane, for example.

An arrangement of a control system and a mobile control module, via which the control system can be remote-controlled. The control system can be supplied with sensor data via signal inputs, and a processing unit of the control system can calculate from the sensor data and from stored lifting device-specific data information characteristic for the current lifting load situation the allowability of work processes on the lifting device, and optionally in the given current lifting load situation. The control system can transmit the information characteristic for the current lifting load situation and/or the allowability of work processes on the lifting device to the mobile control module via a transmitting and receiving module, to the mobile control module in a wireless and/or cable-bound manner. From the information, a processing unit of the mobile control module calculates graphic data for a display via a display unit.

Provided is a single-drum-type cableway carriage that can also be used for lumber-yarding which involves either the raising of a load or the lowering of a load over gentle slopes and steep surfaces.

The cableway carriage according to the present invention includes: a base member 1; a main cable braking member 10 that has a braking face that comes into contact with the main cable and that is secured to the base member; a first lever 20 that has a first fulcrum serving as a center of rotation and secured to the base member, a first lever braking face provided in a position facing the braking face, a biasing member that biases the first lever braking face in a direction of separation from the braking face, and a drive pulley capable of applying a force in the direction in which the first lever braking face is brought close to the braking face by the tensile force of the rope, and a second lever 30 that has a second fulcrum secured to the base member and serving as a center of rotation, and a first lever pressing part capable of pressing the first lever in the direction in which the first lever braking face is separated from the braking face.

A hoist, a hoisting apparatus with said hoist and a method for securing a hoist. A hoist body having a drive mechanism for raising or lowering a hoist chain or a hoist cable is suspended from a support device by a hoist support. A safety device having a loosely arranged coupling element and a damping element is mounted between the hoist body and the support device. If the hoist support is released, the hoist body can drop by a drop height until the coupling element becomes taut. The damping element then damps the fall under the load of the hoist body, the hoist chain and whatever load is suspended from it.
