A jack stand supports a raised machine or component during maintenance. It provides a mechanical backup when hydraulic systems are disengaged.
Technicians should always use proper supports and never rely solely on hydraulic pressure, as failure could result in serious injury.
A jam occurs when debris blocks movement in a broom, conveyor, or duct. It can stop operation and may cause mechanical damage if not addressed quickly.
Before clearing a jam, the machine must be shut down and secured. Frequent jams may indicate improper setup, excessive debris load, or worn components.
A jet nozzle produces a focused stream of water for cleaning or dust suppression. It can be used to target specific areas where buildup is heavy.
Proper pressure and direction are important to avoid damaging components or pushing debris into sensitive areas.
A joystick control allows operators to control multiple functions using a single interface. It may operate brooms, lift arms, or hydraulic movements.
This improves efficiency and ergonomics but requires proper training to avoid unintended movements or misuse of controls.
A junction box protects electrical connections and organizes wiring circuits. It helps prevent damage from moisture, vibration, and debris.
Loose or corroded connections inside a junction box can cause intermittent faults or system failures. Regular inspection is recommended.
