Frequently Asked Questions
Q: What is the CR 79787 contact and how does it differ from the CR 79786?
A: The CR 79787 is an electrical contact assembly similar to the CR 79786 but designed for a different position or amperage rating in the control circuit. Both are used in Crown lift truck controllers, but the CR 79787 may handle different electrical loads or switching functions. Confirm your equipment model to select the correct part.
Q: Which Crown equipment models require the CR 79787 contact?
A: The CR 79787 fits specific Crown electric pallet jack controllers and may be found in walkie riders or low-level order pickers depending on model year and control system design. Check your equipment documentation or controller label to verify the correct contact part number for your truck.
Q: What are the electrical specifications of the CR 79787 contact?
A: The CR 79787 contact assembly is rated for the amperage and voltage of the Crown controller circuit where it is installed. Typical Crown pallet jack systems operate at 24V or 48V DC. The contact is dimensioned to fit the specific solenoid or relay housing in your equipment.
Q: How long does the CR 79787 contact typically last?
A: The CR 79787 contact provides 2-4 years of normal service life in warehouse environments. Lifespan depends on switching frequency, duty cycle intensity, and electrical load consistency. Heavy-use operations may require replacement sooner than light-duty applications.
Q: What symptoms indicate the CR 79787 contact needs replacement?
A: Signs of failure include intermittent electrical response, delayed motor engagement, or complete loss of power. Visual inspection may reveal pitting, burning, or discoloration on the contact surface. If the truck stalls or loses power under load, inspect this contact as a potential cause.
