Compare configurations
Use the truck-mounted and skid-mounted rig comparison when the decision is about mobility, foundation work, rig-up time, transport dimensions and site layout.
Resources
Technical resources for oilfield equipment decisions.
Use these guides to narrow the equipment scope before contacting ZYT Petroleum Machinery. The content focuses on specifications, operating conditions and information a supplier needs to prepare a useful response.
Buyer intent map
Use the guides according to the purchasing question.
International buyers often search by equipment type, operating task and specification requirement. These resource pages connect those searches with product pages and inquiry information.
Prepare specifications
Use the workover and cementing guides to list depth, hook load, pressure, displacement, fluid data and supporting systems before requesting a technical quotation.
Move to product pages
Each guide links back to relevant product models so buyers can review technical specifications, related equipment and the contact path without returning to the top navigation.
Buyer guides
Start with the decision you need to make.
Each guide connects a common purchasing question with relevant products and the technical details that should be confirmed before final equipment selection.
Specification overview
Drilling & Workover Rig Specification Overview
Side-by-side rated specifications across the full product line: hook load, depth rating, power and drive configuration in one comparison.
Engineering calculation
How to Calculate Workover Rig Hook Load
Step-by-step method: string weight, buoyancy factor, block weight and safety margin, with a worked 4,000 m example against real rig ratings.
Field maintenance

Technical reference
What to include in an equipment inquiry.
For a faster and more accurate technical response, include the equipment type, target application, well depth or pressure, expected capacity, operating environment, quantity, destination and any required standards or documentation.
Application
Explain whether the equipment is for drilling, workover, well intervention, cementing, fracturing, production support or rig relocation.
Operating conditions
Provide depth, hook load, pressure, temperature, fluid type, terrain and expected operating frequency where known.
Commercial scope
State quantity, delivery destination, required supporting equipment, documentation and the preferred contact method.
Frequently asked
Questions before contacting a supplier.
These answers help organize the inquiry. Final selection still depends on the available technical documentation and project conditions.
What information should be confirmed before selecting a rig?
Confirm the planned well depth, tubing or drill pipe size, hook load, mobility requirement, site access, operating environment and whether the unit will be moved frequently or installed for long-cycle work.
Should I choose truck-mounted or skid-mounted equipment?
Truck-mounted equipment is generally considered when self-propelled mobility and repeated relocation are important. Skid-mounted equipment is generally considered when the site has a prepared foundation and the equipment will remain in a fixed or centralized operating position.
Can the equipment scope include matched auxiliary systems?
The product range includes supporting equipment such as fluid supply trucks, instrument vehicles, rig moving systems, power equipment and well service units. The final matched scope should be confirmed against the main equipment and site requirement.
