All lift designs feature a self-locking load nut design which cannot spiral down or creep as it is guaranteed self-locking. SLEC uses a touch-screen control screen which is the home base for lift operation as well as providing operational data to the operator to enhance operator safety and lift status. All SLEC’s products are backed up by the company’s factory trained and employed service technicians whose sole responsibility is to take care of customers. Allister Collings, [email protected]
