March 31, 2016, 11:01 am - Loading dock information regularly references TENV Electric Motors and TEFC Electric Motors. What is the difference? TENV stands for Totally Enclosed Not Ventilated Electric Motors. These are used in a wide variety of smaller horsepower applications. This type of electric motor radiates its excess heat through the body of the motor. It is commonly built with special high temperature insulation. TEFC stands for Totally Enclosed, Fan-Cooled Electric Motor. These are constructed with a small fan on the rear shaft covered by housing. The fan is used to assist in cooling the electric motor. Dock levelers commonly use TENV motors and dock lifts commonly use TEFC motors. Contact a Pentalift Sales Representative for further information.
November 30, 2015, 4:13 pm - The majority of dock lift control stations are electrically operated to both raise and lower the platform, so if there is a power failure the control buttons will not operate the lift table. If the dock lift is in the elevated position when the power failure occurs you will not be able to lower the dock lift unless the power unit is equipped with an optional manual lowering valve. The manual lowering valve would be located on the power unit, and when opened, the hydraulic oil in the lift cylinders will be directed back to the reservoir. This will permit the table to lower. Contact your Pentalift Sales Representative for more information.
July 10, 2015, 1:42 pm - Why do most loading dock equipment manufacturers offer both a pit model and a surface model of dock lifts? The majority of dock lifts are manufactured to suit a recessed pit installation. In some applications the site is unable to accommodate a recessed pit, perhaps due underground services and the difficulty and/or expense associated with rerouting them. In this application, temporary applications, or perhaps just for flexibility in the future, a surface installed dock lift equipped with an approach ramp can be the best solution. Pit model dock lifts are available in the most platform sizes, capacity’s and with many more options available. There is a definite requirement for both models of dock lifts; the application generally dictates the right selection. Contact your Pentalift Sales Representative for more information.
Pentalift Lift Tables fabricated to meet ANSI MH29.1:2012, Industrial Scissor Lifts Safety Requirements
January 28, 2015, 5:57 pm - Pentalift fabricates lift tables to meet the standards that are laid out in ANSI MH29.1:2012, Industrial Scissor Lifts Safety Requirements. The standard was developed to establish design and performance criteria that will ensure fabrication of safe industrial scissors lifts. The International Code Council (ICC) has approved the inclusion of MH29.1 into Chapter 30, Section 3001.2 of the International Building Code (more about MH29.1 and IBC).
