Hydraulic engine mobile crane

Part 1: Taking a methodical approach is the best way to get off-highway equipment working again, quickly and safely. Read Part 2 of this article here. It is inevitable that even a well-designed mobile hydraulic system will malfunction at some point. There are many reasons why it might happen.

Contaminants in the fluid may be interfering with normal component functions. The machine may have been used beyond its design limits at some point. Regular maintenance may have been overlooked or a component such as a pump may have been operated past its expected service life. One component in the system may turn out to be less durable than expected by the designers. These are just a few of the common reasons for system faults.

Once a mobile machine is no longer functioning normally, it is common for the next branch of activities and decisions to become quite abnormal or even suboptimal. The operator may notice that functions have become slow. Perhaps winch speed or travel speed has become slow. Another potential problem is that a cylinder or motor is moving too quickly.

These are problems related to the rate of flow. Another type of complaint is a problem with lifting the heaviest of normal loads. The cylinder or motor motion for the lift function stalls completely under these loads. If the machine has hydraulic propulsion at the wheels or tracks, the equivalent fault would be stalled motion on steeper slopes—ones that can usually be climbed without difficulty. Instead of a complete motion stall, the issue might be an uneven, hunting motion at the cylinder or motor.

These types of complaints often point to a problem achieving pressures in the normal, maximum range. Another range of faults might include one machine function that will not operate at all, or perhaps the cylinder will move only in one direction. These issues are often thought of as directional problems.

We have described a range of faults in three different categories, any of which would frustrate a mobile machine operator who was expecting a normal day at work. The temptation for some troubleshooters under downtime pressures might be to go deeply into the heart of the hydraulic system, replacing a pump or a main valve. That would be jumping far ahead in a process that needs some thought and care. A methodical process will usually consume less time and will avoid needless component replacement.

The technician as investigator So, how does a troubleshooter start the process? Start with the operator who filed the complaint. A shop technician might receive a work order with a simple description of the fault. The complaint may not be described as clearly as the earlier examples. Hours may have elapsed since the machine was taken out of service.

Find that operator if possible and ask questions.Metal Working Parts Misc. Contact Us My Account.

Price Match. Your Suburb or Postcode? It quickly folds up designed to save space in the workshop. Very simple to use pneumatic over hydraulic or just manual hydraulic operation via a single acting pump equipped with automatic safety valve to control the lowering speed. The jib extends to the desired lifting capacity of kg, kg, kg or kg secured by a single locking pin.

The lifting range is mm so an engine can be lifted clear out of the engine bay with little effort. With great stability of its wide legs, this crane can also be used to lift machines or other heavy items, making for an excellent piece of equipment for the workshop or warehouse.

Upon closer examination and with some quick measurements, one of the modified cross tube lengths on a cylinder that had been hanging around for project purposes happened to fit the bottom mounting point of the shop crane's frame.

Once the cylinder was in place, the plugs were pulled and the crane moved up and down manually to see if the makeshift mounting job was going to do the trick.

Since it was mostly for show, it did just fine. A 12V power pack without remote and a reservoir that was on sale at the time was used. The crane was then fitted with a BF40 directional control valve with integrated flow control for its flow metering properties, which are essential for setting the right speed for raising or lowering the crane.

The power pack is switched on through the use of a spool-activated micro switch on the BF40 whenever the lever is moved. A counterbalance valve was hard plumbed into the cylinder port to control the crane's rate of descent under load, and also hold the load in position if the hose broke. Battery clamps and welding cable were used to provide power to the power pack and a small battery tray was mounted on the legs of the crane to accommodate a standard size car battery. The 12VDC power pack is a self-contained unit made up of a motor, pump, reservoir and may also have valving.

They come in double acting, single acting, bidirectional and as a pump motor unit. These power units are typically used on truck and trailer hoists, power tailgates, mobile cranes and anywhere 12VDC hydraulic power is needed.

Hydraulic cylinders are linear actuators. When exposed to hydraulic pressure and flow they produce a pushing or pulling force. The three basic types of hydraulic cylinders are single acting, double acting and telescopic. Hydraulic directional control valves are the command center of hydraulic systems. They are used to direct the desired amount of hydraulic fluid to a specific part of the circuit to perform a desired task. There are many types of directional control valves that perform a wide variety of functions in the hydraulic system.

OK View my Wish List.A mobile crane is a cable-controlled crane mounted on crawlers or rubber-tired carriers or a hydraulic-powered crane with a telescoping boom mounted on truck -type carriers or as self-propelled models.

Mobile cranes generally operate a boom from the end of which a hook is suspended by wire rope and sheaves. The wire ropes are operated by whatever prime movers the designers have available, operating through a variety of transmissions. Steam engineselectric motorsand internal combustion engines IC have all been used. Older cranes' transmissions tended to be clutches. This was later modified when using IC engines to match the steam engines' "max torque at zero speed" characteristic by the addition of a hydrokinetic element culminating in controlled torque converters.

The operational advantages of this arrangement can now be achieved by electronic control of hydrostatic drives, which for size and other considerations is becoming standard. Some examples of this type of crane can be converted to a demolition crane by adding a demolition ballor to an earthmover by adding a clamshell bucket or a dragline and scoop, although design details can limit their effectiveness. Before crane were fixed to a position, except for some mounted on flatcarswhich provided some restricted movement.

Appleby Brothers demonstrated steam-powered cranes at Paris in and Vienna in InHenry Coles, manager of Appleby Corp. In the Coles were acquired by Steel and Co. Hiab invented the world's first hydraulic truck mounted crane in Major crane development events include adoption of the internal combustion engine in and the invention of telescopic jibs.

Beforecranes carried additional booms with them to increase height, which increased operating costs. In crane expert R.

Neal, hydraulics specialist F. Taylor, and design director Bob Lester integrated all three and modernized cranes. The Coles Hydra Speedcrane appeared infurther modified with the ton fully telescopic hydraulic boom infollowed in by the ton "Husky" military versions with four-wheel drive. InSteels was forced to merge with the Acrow Group, losing some of their most valuable employees, including Don Hassel and Johnny Johnson who started a new manufacturing processes plant.

With backing from the British Crane Hire Corporation they acquired a small factory unit and ordered every single element of their product from subcontracted suppliers.
