Which statement about hydraulic shoring is not true?

• A. Hydraulic oil is the fluid used in the jacks
• B. The jacks are operated by hydraulic pressure
• C. The shoring system must be installed according to the manufacturer's instructions
• D. Regular inspection and maintenance is required

Answer: (A)

Hydraulic shoring relies on hydraulic pressure to extend the jacks and push the shores outward, creating a stable support system in trenches. The way it’s used requires following the manufacturer’s instructions for setup and configuration, and the system should be regularly inspected and maintained to ensure it remains safe and effective. The statement about the fluid used in the jacks isn’t universally true because the exact hydraulic fluid is specified by the manufacturer for each unit. While many jacks use a hydraulic fluid, the type and grade can vary—some systems may use mineral oil, others may use synthetic or water-based fluids. So, identifying the fluid simply as “hydraulic oil” isn’t guaranteed across all equipment, and the correct practice is to use the fluid specified by the manufacturer. The other points are correct: the jacks operate via hydraulic pressure to apply the force, the system must be installed according to the manufacturer’s instructions, and regular inspection and maintenance are required to keep the shoring safe.
