Product Overview
Rotary Drilling Rig Mast Hydraulic Cylinder
A rotary drilling rig mast cylinder may raise, lower or position the mast through a changing linkage. Yongjian can review drawings for new machines or replacement actuators and prepare a custom configuration for approval. A nominal cylinder bore or machine weight is not enough to establish the loads at every mast angle.

Application and load review
Provide mast mass and attachments, pivot geometry, pin-center positions, stroke, transport and operating conditions, movement time and hydraulic pressure. Review the most demanding compression and tension cases, rod stability and clearances throughout the motion. Identify any loads from vibration, shocks, wind or uneven ground considered by the machine designer. The equipment manufacturer defines machine stability and holding requirements.
Configuration and integration
Bore, rod size, mount pins, bushings, ports, cushioning, seals and rod protection can be specified to the mechanism. Outdoor dust, mud, water and temperature affect wipers, coatings and maintenance intervals. Check hose routing and protection as the mast moves; position indication and holding-valve interfaces require an agreed circuit design.
Inspection and acceptance
Confirm mounting dimensions, full stroke, pressure and leakage tests, surface finish, marking, preservation and any functional checks. For replacement work, verify machine model, serial range and original revision before claiming interchangeability.
Information for a quotation
Send rig and linkage drawings, mast load cases, stroke, closed and extended lengths, mount dimensions, pressure, fluid, environment, quantity and test requirements. Photographs of pin wear or rod damage can help identify recurring site issues. Send drawings and project details to Yongjian for an engineering review and quotation.
Rotary-drilling mast cylinder interface
Mast geometry changes the cylinder force requirement as the rig raises or lowers. The design should use force cases at several angles, including the transition near transport and working positions.
Engineering review
Check rod compression and buckling at maximum extension, pin-bearing loads, cylinder articulation, hose movement, and end-stop energy. Define how the mast is restrained during transport and how unintended descent is prevented during hose or power failure.
Information for a project inquiry
Send mast and linkage drawings, rig mass distribution, stroke, operating time, pressure, mounting interfaces, and field environment. Request dimensional drawings and test criteria matched to the approved machine design.
Product configuration and performance are confirmed from approved project drawings; this section is application guidance.
Project-Specific Configuration
Final technical parameters are confirmed after drawing review and operating-condition evaluation.
