Enerpac Travel Gantry Wins ESTA Innovation Manufacturer Award

The travel gantry features self-contained hydraulics, telescopic cylinders, and wireless controls.
All operations are controlled from the wireless controller and are automatically corrected by Enerpac’s unique software, automatically ensuring synchronous lifting. As an additional safety feature, the system will prevent a lift if it senses overload conditions. The assembly also includes a runner winch that can be used to lift small auxiliary objects. - See more at https://www.whyps.com/News/Hydraulic-industry-articles/enerpac-travel-gantry-wins-esta-innovation-manufacturer-award/72921

Hyspecs Hydraulic Training Seminar

Hyspecs Hydraulic Training Seminar
Hyspecs offers hydraulic training seminar programs for customers and interested parties.

The Hyspecs Hydraulic Seminar:
Is a two-day program covering hydraulic principles and concepts
Is based on an open forum format allowing open questions and discussions from participants to demonstrate theoretical concepts through real life examples.
Involves system design and component selection for a winch circuit.
Covers concepts with basic fault-finding and how pressure, emotions, and money can affect the symptoms of a system that is not working properly.
Offers physical samples of common components failures along with the discussion on why they failed.
Seminar programs are normally carried out in both offices but can be customized to suit client requirements. Custom seminars are also available to suit specific or specialist requirements.

Sennebogen 825 E-Series Material Handler

Sennebogen 825 E Series material handler is a standard machine for multiple uses. It was scrutinized in Regensburg by PVR in February. Series E 825 comes up with a 129-KW powerful Diesel engine and with a reach of 13m. This next-generation material handler is optimally suited for the diverse sorting and loading jobs to be performed in the yard. The mobile variant weighs approx. 28.8 tons. It impresses with optimal serviceability, easy access to all components and a structured layout of its upper carriage.

The material handler is fitted with a genuine SENNEBOGEN SGM multi-shell grab with a capacity of 600 liters and 5 grab shells. The operator's workplace has been ergonomically optimized to reduce fatigue to the minimum. The joysticks have been completely revised and are now even more pleasant to the touch. The panel holding the switches and instruments is directly mounted to the new comfort seat. It follows the seat's movements for optimal operator convenience. Of course, the new SENNEBOGEN 825 E is also fitted with the proved SENCON control system. The cab can be elevated by 2.70 m to provide an optimal view of the work area, as is standard for all SENNEBOGEN material handlers.

Important steps to be taken when changing a hydraulic system from mineral oil to a fire resistant fluid

When a hydraulic system is changed over to water- in - oil emulsion fluid, or a fire resistant fluid, strictly follow the following steps.

• Make sure that the hydraulic system components, especially pumps, valves, motors, and accumulators are compatible with new fluid.
• All the existing oil should be completely drained, cleaned and flushed.
• Drain the existing oil from hoses, pipe works and instruments and make them dry.
• It is essential to get out any contamination which might cause the new fluid to break down
• Most of the seals can be kept undisturbed. Butyl dynamic (moving) seals should be replaced in changing from synthetic fluids; seals must be changed to those rated for petroleum oil use.

Causes of Pressure, Heat, Noise and Vibration in Hydraulic Systems

Causes of Pressure Generation

1. Pressure reducing, relief or unloading valve miss adjusted
2. Yoke actuating device inoperative(in the case of variable displacement pumps)
3. Pressure reducing, relief or unloading valve damaged
4. Clogged Pressure filters
5. Wrong sizing and fabrication of pipework
6. Wrong design of the system
7. Overload the system actuator side above the designed capacity

Causes of Heat Generation

Overheating is one of the most occurring problems in hydraulic actuator systems, people who frequently operate with hydraulic systems will know how much overheating can affect the performance, safety and overall the costs. 

1. Hydraulic fluid is heated
2. Cavitation
3. Air in fluid
4. Relief or Unloading valve set too high
5. Excessive load
6. Worn or damaged pumps
7. Worn or damaged motors
8. Worn or damaged valve
9. System pressure too high
10. Unloading valve set too high
11. Fluid dirty or low supply
12. Incorrect fluid viscosity
13. Faulty fluid cooling system.
14. Wrong design and fabrication of hoses and pipes

Noise and Vibration in Hydraulic Systems

The health and safety issues relating to noise have been recognized for many years and legislation is now placing clear demands on manufacturers to reduce noise levels. Hence, noise reduction in hydraulic systems demands a lot of attention from the industrial as well as academic researchers. It needs a good understanding of how the noise is generated and propagated in a hydraulic system in order to reduce it. The main source of noise in hydraulic systems is the pump which supplies the flow. Most of the pumps used are positive displacement pumps. Of the positive displacement pumps, axial piston swash plate type is mostly preferred due to their reliability and efficiency.

Some of the main causes for Noise and Vibration are as follows: 

1. Cavitation in pump
2. Air in fluid
3. Coupling misaligned
4. Pump wore or damaged
5. Relief valve setting too low or too close to another valve setting
6. Worn poppet and seat
7. Clogged inlet line
8. Dirty Clogged reservoir and breather vent
9. Damaged charge pump (in the case of closed loop pump)
10. Clogged suction filters
11. Lack of anti-vibration pads for the electrical motor.
12. High viscosity oil
13. Lack of proper claim ping's for pipe work
14. Damaged pump bearings

Komatsu Mining Magazine Load and Haul Winner

The Mining Magazine awards celebrate innovation and commitment to advancing the face of mining, not just technologically but also sustainably and in an environmentally respectful manner. Readers nominate the best mines, teams and projects that they have seen throughout the year and then select 11 winners from that pool.

This year Komatsu Autonomous Haulage Vehicle was the winner of Load and haul award. Unlike from its  930E and 830E autonomous models, Komatsu developed this vehicle exclusively as an unmanned vehicle. By distributing equal load to the four wheels, both when the vehicle is loaded and unloaded, and by adopting four-wheel drive, retarder and steering, the vehicle will be able to shuttle in both forward and reverse travel directions, thereby eliminating the need for K-turns at loading and unloading sites.
