XR240E 80m Depth Rotary Pile Drilling Rig for Sale

Product Introduction

As a multi-functional machine, XR240E can realize the quick switching of functions such as crowd cylinder, crowd winch to meet more different construction needs.

Product Advantage

It adopts Isuzu electronically controlled turbocharged engine with lower fuel consumption and convenient service.

The rotary drive and main winch performance is increased by 20%, so the work efficiency is much higher.

The main and auxiliary winches both adopt the single-row rope technology, the service life of wire rope is 2~4 times longer than that of multi-layer rope, which makes the cost lower.

The double jib parallelogram luffing mechanism has a large support angle and al6% increase in support range, which makes the operation more stable.

The hydraulic system adopts negative flow control technology which has a fast response and good handling performance.

High-power temperature-controlled independent hydraulic oil cooler can meet the construction requirements of high temperature areas and adjust the fan speed according to temperature changes to achieve energy saving.

Technical Parameters

Product Uses

The XR240E rotary drilling rig is widely used in the drilling operations of concrete cast-in-place piles in projects such as highways, railways, Bridges, and large venues.

Product Operate Guide

Pre-assignment inspection and preparation

Equipment inspection: Before starting up, please conduct a comprehensive inspection of whether all components of the drilling rig are complete, whether the connections are firm, and confirm whether the liquid levels of hydraulic oil, fuel oil, etc. are normal and sufficient.

Site confirmation: Ensure that the drilling rig is parked on a stable and solid site. Avoid operating on inclined or soft ground to prevent danger.

Drill installation: According to the specific construction requirements, select the appropriate drill pipe and drill bit, and install them correctly on the drilling rig.

Startup and Positioning

Start the rotary drilling rig as required by the equipment manual, observe the instrument panel, and ensure that all systems are operating normally.

Use the traveling mechanism of the drilling rig itself to move it to the predetermined working position.

Adjustment and drilling

Adjust the Angle of the mast according to the construction requirements.

The XR240E is equipped with an automatic leveling and display function for the verticality of the drill mast, which can help you position more accurately.

Use the mast guide to lower the drill pipe and align the drill bit with the hole position.

Start the power head device to provide torque for the drill pipe. Meanwhile, the pressurization device transmits the applied pressure to the drill pipe and the drill bit, and they begin to rotate and break the rock and soil.

FAQ

1.What are the special features?

One of the highlights of XG XR240E is its "multi-functionality in one machine". It can quickly switch between multiple working modes, including cylinder pressurization and hoist pressurization. It can also be adapted to pipe rolling machines, long spiral drills, and even upgraded to dual power heads to meet different engineering construction requirements.

2.Which configurations can be selected?

Users can choose to install torque multipliers (the driving torque of the casing can reach 360kN·m after selection) and chassis transport outriggers according to their actual construction needs. These optional parts can further enhance the equipment's capacity under specific working conditions and the convenience of relocation.

3.What intelligent designs are there for the operation?

This drilling rig is equipped with an intelligent control system, which realizes functions such as automatic leveling and display of the verticality of the drill mast, automatic rotation, and automatic soil throwing. Under the long spiral method, automatic lifting and pouring as well as pile shape display can also be achieved, effectively enhancing operational convenience and reducing the possibility of misoperation.

4.What are the key points of daily maintenance?

Daily maintenance points to note:

Steel wire rope: Both the main and auxiliary winches adopt single-row rope technology. This design can extend the service life of the steel wire rope by 2 to 4 times compared to multi-layer rope structures. Daily attention should be paid to observing the wear condition.

Hydraulic system: Pay attention to the oil level and temperature of the hydraulic oil. The equipment is equipped with a high-power temperature-controlled independent hydraulic oil cooler to adapt to high-temperature working conditions.

Structural components: Regularly inspect key structural components, such as the boom luffing cylinder, to prevent oil leakage due to damage caused by accidents (such as electric shock, bumps).

5.What should I do if the engine won't start?

If the engine fails to start, you can follow these steps to troubleshoot

First, check if the battery is undercharged and if the circuits are loose or corroded.

Check whether the teeth of the starter motor are worn or whether the spring is broken.

Check whether there is voltage in the starter electromagnetic coil.

If there are no issues with the above, then it is necessary to check the engine itself, such as whether the crankshaft rotation is blocked.

6.How to troubleshoot oil leakage in the power head?

If there is oil leakage at the oil seal of the power head skeleton, the following methods can be referred to for troubleshooting:

Check whether the lips of the skeleton oil seal are worn or scratched, and replace them if necessary.

Check whether the contact area between the main shaft and the oil seal is scratched. If there are scratches, the main shaft and the oil seal may need to be replaced.

If the main shaft and the oil seal have good contact but there is still oil leakage, it may be that the axial clearance of the bearing is too large. The adjustment gasket of the bearing end cover needs to be adjusted to ensure that the clearance is between 0.08mm and 0.15mm.
