Apparatus for processing a sheet-metal workpiece includes a press tool including a bottom die and top die. A press includes a platen which receives the bottom die, and a ram which receives the top die. The press tool is protected by a protective system which detects an idle stroke and includes an adjustable spacer assembly to prevent collision between the top and bottom dies.

Belt traps for a belt drive system include a bracket configured to receive at least a portion of a pulley to capture a failed drive belt between the bracket and a pulley. The pulley may be a tensioner pulley and may be biased in a direction towards the bracket. The bracket may include a relief portion configured to receive at least a portion of the pulley. The relief portion may include an opening or a recess that is sized and shaped to receive at least a portion of the pulley.

The system comprises a mounting frame suspended above a ground level. The system comprises a modular panel configured to removably attach to the mounting frame and removably interconnect with other modular panels to form a barrier. The modular panel comprises multiple ballistic sub-panels that are configured to removably attach to the modular panel and interconnect with each other to increase the surface area of the modular panel and where each ballistic sub-panel is constructed of a ballistic-resistant material. The system comprises a ballistic detection system comprising at least one sensor configured to detect a ballistic event. The ballistic detection system comprises a notification system configured to communicate a notification to an emergency service in response to the ballistic event. The ballistic detection system comprises a controller configured to determine the severity of the ballistic event and activate the notification system and a power supply.

A fire apparatus system includes a fire apparatus and one or more processing circuits. The fire apparatus includes an aerial ladder and an environment sensor positioned along the aerial ladder. The environment sensor is configured to collect data regarding a weather characteristic at a location of the fire apparatus. The one or more processing circuits are configured to acquire the data collected by the environment sensor, monitor the weather characteristic at the location based on the data, and transmit a notification or a command to one or more devices based on the weather characteristic.

A vertical protective device for a medical display hanger comprises a contact piece, a microswitch, a rotating shaft and a vertical protective plate, wherein the contact piece is connected to one end of the rotating shaft, the vertical protective plate is connected to the other end of the rotating shaft, and the microswitch is arranged on a microswitch support; and when a collision of the vertical protective plate happens, the rotating shaft drives the contact piece to rotate, and the contact piece triggers the microswitch, so as to control the medical display hanger to stop moving or immediately rise. When an accidental collision of the medical display hanger happens in a substantially vertical direction, the medical display hanger can effectively come to an emergency stop.
