SANY 60014117 Hydraulic Steering Gear Assembly for Truck Cranes

Product Introduction

The SANY 60014117 is an original equipment hydraulic steering gear assembly designed for SANY truck crane and mobile crane chassis steering systems. It forms a key part of the vehicle’s steering control loop, translating driver input into precise hydraulic steering force and helping maintain stable directional control during road travel, job site positioning, and low-speed maneuvering.

As an OEM part marked under SANY number 60014117, this unit is manufactured to meet the original chassis layout, mounting interface, and hydraulic performance requirements. It is supplied as a complete steering gear assembly ready for installation, including the main housing, internal steering mechanism, piston or rotary control elements, seals, and associated mounting components.

Function & Operating Principle

This steering gear works in conjunction with the crane’s hydraulic power steering circuit. When the driver operates the steering column, the control valve inside the steering gear directs pressurized fluid into the appropriate chambers of the steering mechanism. The hydraulic pressure then assists the movement of the steering linkage, reducing the effort required to turn the front wheels and giving the operator consistent, predictable steering response.

In heavy truck crane applications, reliable steering is particularly important because the vehicle operates at different gross weights, on mixed road surfaces, and in confined construction sites. The 60014117 steering gear is engineered to support smooth steering under both light and loaded conditions, contributing to safer vehicle control and more accurate crane positioning.

Construction & Design Features

The assembly features a robust cast alloy housing designed to withstand mechanical stress, vibration, and hydraulic pressure fluctuations typical of heavy-duty vehicle operation. The main body is precision machined to maintain accurate internal alignment of the valve, piston, and steering linkage components.

Internal sealing elements are selected for compatibility with standard hydraulic oils and for long-term service under varying temperature conditions. External seals and cover plates help limit oil leakage and protect internal parts from dust, dirt, and moisture. The bolt-on base flange and standardized mounting points are intended to match the original chassis installation, supporting direct replacement during maintenance.

The unit also includes a top steering column connection interface and lateral hydraulic port connections. These interfaces allow the steering gear to be integrated into the existing steering column and hydraulic circuit without additional adaptation work.

Technical Specifications

Application Scope

The 60014117 steering assembly is used in SANY truck crane and mobile crane chassis where original steering system replacement is required. It is suitable for maintenance repair, chassis overhauls, and steering system restoration work. Common application scenarios include crane fleet maintenance, construction equipment repair workshops, and heavy-duty vehicle service operations.

Because different SANY crane models may use similar-looking steering components under different part numbers, replacement should always be confirmed by comparing the OEM part number and physical mounting configuration before installation.

Installation & Maintenance Notes

Before installation, inspect the steering gear for any external damage, damaged seals, or contamination. Verify that the mounting flange, bolt holes, steering column interface, and hydraulic ports match the original equipment configuration.

During installation, use the original bolt tightening sequence and torque values where specified. After connecting the hydraulic lines, check for proper oil flow direction and ensure all connections are free from leaks. Once installed, bleed air from the steering system according to the vehicle or chassis manufacturer’s procedure, then test steering response from lock to lock.

Regular maintenance should include checking for external oil leakage, loose mounting bolts, abnormal noise, and heavy steering effort. Any sudden change in steering performance should be diagnosed immediately to avoid compromised vehicle control.
