Standout Scissor

On the company’s 19-foot scissor offering, the 1932ES, MEC employs square-tube guardrails, a punch-pressed platform floor, and a roll-out deck with six incremental locking positions. The deck deploys on four different poly rollers: two up front and two in the mid

MEC uses a patented single-beam scissor linkage on its 1932ES. The company believes this unique feature minimizes deflection. Specifically MEC believes that reducing the number of pivots points, fixing one end of the linkage pin to the beam, and line boring every bushing after it has been welded into the scissor beam adds to the unit’s rigidity. The company also uses large 1-7/8-inch pins to get more bearing surface. These hardened chrome pins ride on Teflon bearings to eliminate maintenance on the scissor stack.

For the lifting mechanism, MEC uses a non-displacement cylinder that has a sealing mechanism at the end of the cylinder housing. According to the company, it has bolted a piston at the end of the rod located inside the lower section of the cylinder. As the oil flows in, it immediately pressurizes the housing and displaces the rod. Not only does this keep oil from seeping out, but it also enhances the 1932ES’s elevation speed. If the piston ever starts to seep, a backup seal at the boom forces the oil to return to the hydraulic tank.

MEC has a 5° incline limit, and the tilt sensor activates at 2° fore and aft and 3° side to side. The lower control housing protects the tilt sensor from outside debris that may fall on the machine. According to MEC, the most complex part of the control system is the proven Sevcon motor control, which manages the speed of the electric motor in relation to the speed of the joystick. “The idea is you don’t need a laptop or analyzer,” says Jim Tolle of MEC. “All you really need is a test light to fix these machines.”

To extend service life, all hydraulic hoses in contact with metal are encased with a hardened plastic spiral wrap or steel coil to prevent chafing. To protect connections from steam cleaning or pressure washing and prevent condensation, every

On the “flex-free” rigid chassis, the 1932ES does not h ave swing-out or pull-out trays. Instead, the single door swings up or the covers pull off to completely to expose the batteries. Powering the unit are four 220 amp-hour, six-volt batteries with 245 amp-hour batteries available as an option. If the batteries become drained to a level of about 14 volts, lift is cut out to let the operator know the batteries are low. At 10 volts, the machin e completely shuts down, protecting the components. The universal charger is designed so it will turn on even if the power source is less than ideal.

The MEC 1932ES features a powder-coat finish. Options on the machine include an inverter, swing gate, folding guardrail systems, and lanyard attachments.

Lift and Access perspective: One of MEC’s competitors commented at the event that this unit was a great value proposition and it is easy to see why he felt th at way. The fit and finish are exceptional and there really isn’t much not to like. The guys at MEC are self proclaimed “gear heads” and that is evident in the way this
