Abrégé

A conveyor take-up device may include a carriage, a pulley, a counterweight assembly, at least one connector, and at least one safety restraint. The carriage may be movably joined to a support structure and may support the pulley, which may be configured for operative association with an endless conveyor belt. The counterweight assembly may include a counterweight arm, a tension arm, and a counterweight. The counterweight arm may be pivotally joined to the support structure and configured to move between upper and lower limit positions. The tension arm may extend generally transversely from a first end portion of the counterweight arm with the counterweight supported by the counterweight arm distal from the tension arm. The connector may be joined to the carriage at one end portion of connector and to the tension arm at a second end portion that is distal the first end portion of the connector.

The invention relates to a belt-conveying installation (1) for heavy industry, in particular for the extractive or mining industry, comprising at least one carrying structure (2), a conveying belt (3) and at least one drive apparatus (4) for driving the conveying belt (3), wherein the drive apparatus (4) comprises at least one drive shaft (5), at least one drive-shaft-bearing arrangement (5a), at least one drive roller (6) and at least one independently excited drive motor (7) in the form of a frequency-converter-fed alternating-current synchronous motor with a stator (7a) and a rotor (7b). The drive shaft (5) and the at least one drive motor (7) are connected to one another without any gearing, and the rotor (7b) and drive shaft (5) are arranged coaxially, each drive shaft (5) being guided through at least one rotor (7b). The invention also relates to a method for operating such a belt-conveying installation and to the use thereof.

Abrégé

A material handling machine for transferring discrete loads of excavated, uncrushed waste from an excavator or other excavation equipment (3-5) to a dumping location beyond the reach of the excavator. The material handling machine may include a mobile bridge (1) supported by two or more crawlers (2,3). The material handling machine may further include at least one skip (12, 13) that is selectively moved between a first end (4) and a second end (5) of the mobile bridge (1). The at least one skip may receive material from excavation equipment at the first end (4) and deposit the received material proximate the second end. When the material handling machine includes two skips, one skip may be positioned above the other skip, or the skips may be positioned to be side -by- side.

A pipe conveyor may include a conveyor belt formed into a pipe-like shape to define a space that contains material to be transported by the conveyor. Along at least a portion of the pipe conveyor, friction drive conveyors or friction tires may be positioned. The friction drive conveyors may include friction drive belts that engage the pipe conveyor belt. Via this engagement, the friction drive conveyors apply a force to the conveyor belt that moves the conveyor belt in a desired direction. Further, when the friction drive conveyors or friction tires are positioned within an inclined vertical section of the conveyor belt, the friction drive conveyors or friction tires vertically lift the pipe conveyor belt via pushing the conveyor belt in a vertical direction, thus assisting a drive pulley that vertically pulls the conveyor belt and material transported on the conveyor belt from a lower elevation to a higher elevation.

Abrégé

A conveyor system for an open pit mine may include one or more conveyor lines. The conveyor lines are used to transport material from one location in the mine to another location. The material transported may be a waste material, such as overburden material, or coal. The conveyor lines may move from a first end of the pit to a distal second end. When the conveyor lines reach the second end, they may reverse direction and return towards the first end. During this reversal in direction of travel, equipment may be selectively swapped between the conveyor lines. The conveyor lines may include at least one mobile bridge conveyor. Each mobile bridge conveyor may support one or more conveyors that transport the material.
