Step Jacks, also known as Climbing Jacks: They are synchronized lifting devices designed to raise field-erected storage tanks in accordance with API 650 and API 653. The tank is lifted from the outside to allow Annular Ring Replacement, Annular Plate Restoration, Tank Foundation Removal, and Tank Bottom Plate Replacement. Step Jacks temporarily lift and support existing storage tanks during the repair or replacement of annular bottom plates located beneath the tank shell. These systems allow damaged annular plates to be removed and new plates installed while minimizing downtime and project costs. The equipment is also used for major rehabilitation projects, such as tank bottom plate replacement, in which all or part of the tank floor is removed and replaced due to corrosion, leakage, settlement, or structural deterioration. In addition, it supports tank foundation removal and rehabilitation activities, including foundation replacement, settlement correction, annular ring restoration, and tank relocation projects. Together, these systems provide a comprehensive solution for storage tank maintenance, repair, reconstruction, and life-extension projects, ensuring safe, efficient, and cost-effective execution of critical tank repair operations.
Applications:
• Annular Ring Replacement Step Jacks are designed to raise and support existing field-erected storage tanks during the replacement or restoration of the annular ring plates located beneath the tank shell.
• Annular Plate Restoration (Repair) Climbing Jacks are used during the repair, replacement, or restoration of the annular bottom plates of existing field-erected storage tanks without dismantling the entire tank. These jacks temporarily lift and support the tank shell so that damaged annular plates can be removed and new plates installed safely.
• Tank Foundation Removal (Repair): Step Jacks are used to dismantle and remove all or part of the existing foundation supporting a field-erected storage tank, allowing it to be repaired, rebuilt, or replaced. This work is commonly performed during major tank rehabilitation, settlement correction, annular ring replacement, or tank relocation projects.
• API Storage Tank Repair and Maintenance Step Jacks comprises specialized tools and lifting systems used for the inspection, maintenance, repair, reconstruction, and life extension of field-erected storage tanks used in the oil, gas, petrochemical, water, mining, and energy industries.
• Tank Bottom Plate (Floor) Replacement Climbing Jacks is a major maintenance and reconstruction procedure that involves removing and replacing all or part of the bottom plates of an existing field-erected storage tank due to corrosion, leakage, settlement, or structural deterioration. This work is typically performed in accordance with API 653 requirements.
Notes:
1. Max Lifting Height: The step-climbing jacks are intended solely for lifting existing storage tanks from the exterior to permit annular ring replacement, annular plate restoration, tank foundation removal or repair, tank bottom plate replacement, and related maintenance work. The maximum permitted lifting height is 600 mm, measured vertically to the underside of the tank bottom or annular plate. The equipment must not be used for the construction of new tanks.
2, Max arc-distance between two consecutive Jacks: It must never exceed 5.50 m for stability reasons.
3. Max Jacks working capacity must never exceed 40 MT. The user must take into account the tank lifting weight and snow load at the Jobsite
4. Foundation: The "Buyer or Renter" is solely responsible for providing a pad foundation with a minimum ground bearing capacity of 250 MT/m² beneath each 1.50 m x 1.50 m support pad using 50 MT jacks. Warnings: A licensed geotechnical/lifting engineer hired by the "Renter" must evaluate the footing subgrade to confirm it meets the load-bearing requirements, in accordance with applicable local and federal foundation regulations. Irizar Heavy Industries Inc. is not liable for any accidents resulting from inadequate or improperly designed foundations, including property damage, bodily injury, or death.
5. Roof Support Columns: For tanks with roof support columns, each step jack shall be installed directly beneath a column to maintain vertical load alignment. The "Buyer or Renter" is solely responsible for having its qualified engineer evaluate, design, and approve the method and sequence for temporarily supporting each column, cutting the required section from its base, and sliding the step jack underneath. Each jack shall be installed and fully loaded (pressurized) one column at a time before proceeding to the next. Irizar Heavy Industries Inc. assumes no responsibility for the engineering design, cutting procedure, temporary supports, or any consequences arising from these operations,
6. Wind Speed: The “Buyer or Renter” is responsible for determining site-specific wind restraint. Tank lifting must not proceed, and the tank must not remain elevated, during wind conditions that exceed the approved lift plan or safe site conditions. Where required, guy wires, tensors, bracing, anchorage, and temporary stability measures must be installed by the “Renter” to prevent tank movement, sliding, or overturning.
7. Cribbing Blocks: The “Buyer or Renter” must only use the Irizar UHMWPE Poly Cribbing Blocks supplied with the equipment. Irizar Heavy Industries Inc. is not liable or responsible for any accident, injury, equipment damage, tank damage, site damage, loss, or failure caused by or related to the use of improper, substitute or unauthorized cribbing materials.
8. Insurance: The “Renter” is responsible for providing and maintaining adequate insurance coverage for the rented equipment for its full replacement value while the equipment is in the Renter’s possession, care, custody, or control. This coverage must include, but is not limited to, loss of equipment, theft, damage during use, damage during transportation, loading, unloading, storage, and return shipping. Proof of insurance is required before the equipment is released. The insurance certificate must name Irizar Heavy Industries Inc. as Loss Payee with respect to the rented equipment. Any deductible, uninsured loss, damage, theft, missing equipment, or loss of equipment remains the Renter’s full responsibility. The rented equipment and replacement value breakdown are listed in the Rental Equipment Inventory.
9. Training: Available either online or in person at our Wetaskiwin, AB, facility, included at no additional cost. The course is designed for a maximum of four operators and can be completed within a single day. Upon successful completion of the training and final evaluation, Irizar will issue an operation certificate
10. Features: 1. Quick couplers: prevent oil leaks during testing, assembly, or disassembly; 2. Jacks can perform at extreme temperatures: from -40°C in the Canadian Arctic or Russian Siberia to +60°C in Saudi Arabia or the Middle East. For the safety of your employees, always follow the rules and standards of the OSHA Act of 1970
