Frequently Asked Questions
Q: What are the material specifications for the AT Z-1134 spring?
A: The AT Z-1134 is an OEM compression spring manufactured from high-tensile, spring-grade carbon steel. This material composition ensures consistent spring force delivery and resistance to fatigue under repeated compression cycles in hydraulic systems.
Q: Which Atlas pallet jack models use the AT Z-1134 compression spring?
A: The AT Z-1134 spring is designed for the Atlas Zenith (Type 9) manual hydraulic pallet jack unit. It is installed within the hydraulic assembly and provides spring action for the hydraulic release mechanism.
Q: What is the function of the AT Z-1134 spring in the hydraulic unit?
A: The AT Z-1134 provides spring return force for the hydraulic release mechanism. When pressure is released from the hydraulic pump, this spring assists in restoring the mechanism to its neutral or lowered position, enabling controlled descent of the load.
Q: What failure symptoms indicate the AT Z-1134 spring needs replacement?
A: Common failure signs include loss of hydraulic pressure hold (jack drifts down under load), sluggish or incomplete descent operation, or visible spring deformation. Corrosion on the spring surface may indicate moisture intrusion into the hydraulic unit.
Q: How does high-tensile carbon steel affect spring lifespan?
A: High-tensile spring-grade carbon steel provides excellent fatigue resistance under repeated compression cycles. However, exposure to moisture or corrosive environments can compromise longevity. Springs used in cold storage or wet environments may require replacement sooner than those in dry indoor conditions.
Q: Can the AT Z-1134 spring be used as a replacement for other Atlas models?
A: The AT Z-1134 is OEM designed specifically for the Atlas Zenith (Type 9) hydraulic unit. Do not substitute springs from other models or manufacturers, as different spring rates will affect hydraulic operation and load control.
