  1. Floor Jacks vs. Trolley Jacks… What is the Difference?

    What is the big difference between trolley jacks and floor jacks? This is a question asked often while shopping for the right equipment for the job. When raising a vehicle for service or maintenance, consider these two important factors: the vehicle weight and the height of the lift point. In addition to these details, it is also key to consider the service type, portability, and price. With safety being key when choosing the right jack, there are several differences between floor jacks and trolley jacks that may lead you to prefer one style or another.

     

    Beginning with visual aesthetics, both trolley jacks and floor jacks look very similar in design with minor details typically found in the handle, piston, and saddle. Trolley jacks are typically preferred by most professionals, including DIYers home garages because of their robust and heavy structures, reliability, and versatility to accommodate an array of applications. Floor jacks are a popular, low-cost lifting solution, although typically recommended for infrequent use.

     

     

    The biggest differences between trolley jacks and floor jacks are the range of lifting heights. Trolley jacks typically boast a wider range of clearance, including a super low-profile minimum height, allowing for use on a variety of luxury and sports vehicles. This wider range of vehicle applications makes service and tire changing an easier task on cars, trucks, and SUVs. Other differences between the jack styles can be found in the structure and internal components. Typically, floor jacks have a lighter construction, allowing for ease of portability. Trolley jack constructions are more commonly constructed from steel and contain a release-spring that allows the operator to release the jack at an accelerated, efficient speed.

     

    When choosing your shop and service equipment, the application is an important factor to analyze before making a purchase. Trolley jacks are for light, up to heavy-duty applications. Built to withstand vigorous use, trolley jacks are an easy go-to resort for reliable lifting. Some trolley jacks also include special safety features like quick foot-pump lifting or twist and turn quick-release handles found on the ESCO Model 90521 3 Ton Trolley Jack. Special safety features on these specific trolley jacks provide the operator with controlled accuracy while meeting the safe lift point on a vehicle.

     

    Overall, there are many similarities between floor jacks and trolley jacks. When shopping and selecting new lifting equipment for your garage or mobile fleet, keep in mind the weight and height of the vehicles or equipment being serviced and especially the brand of jack, as there are some companies that offer exclusive warranties, a benefit for jacks being used more frequently. Unfortunately, there is no one-size-fits-all jack suited for all applications but selecting the best tools for the job is the safest decision when relying on a manual hydraulic jack for any type of lifting.

     

    Important Note: Floor jacks and trolley jacks are not designed to sustain the load while service or maintenance is conducted on a vehicle or piece of equipment. Jack stands should always be used in combination with a jack to safety to sustain a load. Load shifts occur when jack stands are not used in combination with a jack and can result in serious injury and/or damage to equipment or vehicle.

     

  2. Air-Powered Tools Are Dying for These Maintenance Tips

    Why Regulate Air Pressure?

    In the scope of hydraulics and air tools, it is easy to assume that more air translates as more power, but what does this mean for the condition of the internal mechanisms and life of your tools? It may go without saying, but any tool from a reputable manufacturer will have operating air pressure guidelines. In the event of tool and equipment malfunction or failure due to being over-supplied with air, chances are this will void the manufacturer’s warranty. Lengthening the life of your hydraulics and air tools is as simple as maintaining your equipment and regulating air pressure supply per manufacturer’s instructions.

    Run Efficient

    In the circumstance of air regulation, regarding air-powered equipment, less is more. For air/hydraulic pumps, the lower recommended air pressure allows for an air motor to run at maximum efficiency. Overworking your compressor or tools will eventually lead to failure, causing equipment downtime and the expense of repairs or replacement. For an accurate flow of air and to prevent any “pulses,” typically initiated when air compressor cycle and pressure builds within the compressor tank and air hose lines, consider adding a simple, affordable regulator or air pressure reducer to your equipment air line assembly.

    Air reducers are a simple, tamperproof device that can be easily installed to the air line assembly of an air-hydraulic pump or air tool to control the air entering the equipment from a compressor. By reducing the air to the recommended pressure, air-powered equipment can avoid being exposed to air pulse irregularities that could lead to equipment malfunction. In order to combat these common issues with air operated tools and equipment ESCO manufacturers air pressure reducers which are available in preset values; 90 PSI for air tools and 110 PSI for air hydraulic pumps. Air regulators also provide the same accuracy and steady flow of air. However, they allow for the reduction and increase of air, which can lead to improper adjustments to manufacturers’ recommended settings.

    Lengthen the Life of your Equipment

    Most air tools on the market are designed to run on 90 PSI while most air/hydraulic pumps run on 110 PSI. Exceeding the manufacturer’s recommended air pressure can damage components, shortening the tool life, and lead to equipment failure, resulting in the voiding of the warranty. For air tools and air/hydraulic pumps, operating at the lower recommended air pressure means in addition to efficiency, less wear and tear will occur to the motor, internally.

    In addition to providing the optimal air flow, ESCO’s Air Pressure Reducers contain an internal filter preventing particulates and dust from entering the air motors of air/hydraulic pumps and/or air tools. The application of an air pressure reducer can also assist in preserving the life of your air compressor by running at a lower, optimal pressure. Air pressure reducers can only lower pressure, so they are manufactured to provide the necessary PSI with every use. Lower air pressure means less work for the air compressor.

    Equipment Failure Prevention 

    Replacing or repairing air-powered tools is expensive, costing upwards of $300.00 USD to replace gasket and seals depending on the severity of the damage. Air pressure regulation assists in the prevention of equipment failure and long-term internal damage to your air-powered tools and equipment. Lengthen the life of your tools and run efficiently by following the manufacturer’s maintenance procedures and regulating air to recommended air pressure.

    Have air-powered tools out of commission? Be sure to contact a reputable air/hydraulic or air tool specialist like ESCO’s Full-service Hydraulic Repair Specialists to have your malfunctioning tools evaluated as they may be repairable. For any other questions regarding repairs or air pressure regulation products, contact an ESCO representative by email at repairs@esco.net or call 352-754-1117.
