Tech Tips

Electrical connectors are an effective and durable way to make terminal connections at valve coils, wiring harness connections, and various other locations on equipment. Enclosed wiring terminals help to protect against corrosion-causing moisture, however, they can be susceptible to water intrusion. Time, pressure washing, improper or loose re-assembly, and damage are all factors that contribute to failure of a connector.

Skyjack is constantly improving and developing new products for our customers. We recently added a motor controller option to our electric scissor models and have redesigned our telehandler line with the new TH series. The T and AJ model boomlifts are still relatively new with an 86-foot straight stick boom being the latest addition. An 85-foot articulating boom will debut soon.

As a required part of each inspection, wheel assemblies and their connection to the machine must be checked. This includes looking for any signs of damage and ensuring that the wheel bolts are properly tightened. If any wheel bolts are found to be loose or not at the correct torque value of 90 ft-lb (122 Nm), each component (wheel rim, wheel bolts, hub) should be inspected to ensure that there is no damage, prior to re-assembly.

The pothole protection system on the Skyjack SJIII model DC electric scissor lifts is designed to reduce ground clearance and assist in the stability of an elevated aerial platform in the event the aerial platform encounters a “drop-off” or “pothole.” As with all safety devices, periodic inspection and maintenance is required to ensure the proper operation of the pothole protection device.

The electrical circuit terminal blocks used in the Skyjack Aerial Work Platforms are a method to neatly and securely terminate wires of the same circuit at a common point. Each terminal block can hold four conductors of the same circuit. Each block is attached to a metal rail mounted to the panel or control box and are ‘stacked’ side by side to form one terminal strip assembly.

The joystick on our Vertical Mast and Electric Scissor lifts have two outputs. One output is a system voltage output to operate the pump motor, valve coils, and relays. The other output is the speed, or proportional signal. This is a variable output signal relating to the speed desired for the function.

Many of the engines we use in our scissorlift and boomlift models utilize a simple pull solenoid to operate the engine throttle and choke. The solenoid consists of a steel plunger that is placed inside a wound coil of copper wire. When this coil is energized, a magnetic field is produced which draws the plunger into the magnetic field. The other end of the plunger is connected to the throttle or choke lever to be operated.

The Skyjack engine powered rough terrain scissorlift and boomlift models can be equipped with a hydraulic generator option to supply AC power to the platform. Some boomlift models can be equipped with a welder package option to power a small welder in the platform.

It is important to ensure that when performing maintenance or a repair procedure, any hoses or electrical cables that may have been replaced or moved be returned to their original positions. As the equipment is operated, the hoses and cables flex and bend, and without proper support, this action causes a straining and pulling tension on them. The use of support clamps, cable ties, along with using the correct fittings and correct hose and cable lengths minimizes or eliminates this tension to help ensure a long life.
