Tires and Tire Quality

Mobile elevating work platforms (MEWPs) will typically use 3 to 4 types of tires: moulded, pneumatic, foam filled, or solid.

Moulded tires are usually solid rubber tires that are moulded onto a steel rim. These tires are available in smooth or treaded surfaces and black or non-marking designs. Moulded tires are most commonly found on slab scissor lifts.

1600403 JLG Joystick Calibration Process

A customer recently contacted C-Tech who had purchased a 1600403 replacement joystick for the JLG 260MRT, 3369LE, 3394RT, or 4394RT scissor lifts, and was having some trouble with the joystick. Having issues with your joystick can be frustrating, but sometimes the fix is as easy as performing a calibration procedure using the JLG analyzer. In this article, we will go through the calibration process steps in order to install a 1600403 JLG replacement joystick.

Battery Troubleshooting

Batteries and battery products are the heart of your Mobile Elevating Work Platform and are responsible for ensuring your electric scissor lifts and boom lifts are working throughout the day. Most electric boom and scissor lifts are designed to offer a complete day of work on a full charge. A battery pack not showing a full charge after being plugged in overnight, or a machine running out of power well before the end of a workday, are red flags that some maintenance or replacement of battery system products are required.

Types of Switches and How They Work

Switches are very simple components that are typically open or closed and act to interrupt or complete an electrical circuit. Some switches are self-contained and others require multiple pieces, such as an actuator, base, and contacts. The most common switches are push button, toggle, and rotary and C-Tech has you covered with a huge inventory of switches for your construction equipment. Let’s dive into the different types of switches and how they work.

TECH TIPS

ENGINE WON'T START?

Imagine you have just tried starting the engine of your boom lift, rough terrain scissor lift, or telehandler but it spits and sputters. Have no fear! The experts at C-Tech are here to help!  We carry a wide array of ignition associated parts from oil pressure switches, spark plugs, solenoids, glow plugs, and sensors to fuel related parts and engine governors.

It’s common that machines equipped with carbureted engines may encounter difficulty starting in weather conditions of 15°-20° F or colder.  After a few unsuccessful attempts of starting the engine, you should troubleshoot the cause of the starting difficulty by checking the carburetor, ignition system, and fuel system.

FILTERS

Filters are often an overlooked part in most daily maintenance checklists, but it is important to know that it only takes a tiny amount of dust to ruin engines or contaminate hydraulic systems. With your equipment on the line, daily inspections of your filters are critical.

JOYSTICK TERMINOLOGY

What is a joystick controller? A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Some joysticks are proportional, meaning that a variable electrical signal controls the stroking of the valve spool over metering ports. This produces a variable flow of hydraulic fluid thereby providing the ability to vary the speed of the actuator being controlled. This variable positioning allows spools to be designed with metering notches to provide flow/speed control as well as directional control functions all in one valve, instead of requiring separate valves for direction and speed. To put it simply, the further your push the joystick from center, the faster the equipment will go. Many of these proportional joysticks can be adjusted slightly with trim potentiometers on the board.

NATIONAL SAFETY MONTH

With June being National Safety Month, it is the perfect time to discuss mobile elevating work platform (MEWP), scissor lift, and boom lift safety.  As we all know, safety is something that we all must practice on a daily basis. The National Institute for Occupational Safety and Health (NIOSH) reviewed data and indicated that the extended height of the lift or the vertical position of the worker as a result of the lift were significant factors for fatal injury.

C-Tech Control Boxes

Recently a customer contacted us requesting some parts to repair a SkyJack® Control Box.  The customer said they needed a quote on a new Joystick, Battery Indicator, Lift Toggle Switch, Key Switch, and Emergency Stop Switch. Our Customer Support Specialist then asked why they needed all of those parts, and the customer informed us that he was repairing an old used control box after theirs was stolen. Our team worked to identify the model and serial number of the Scissor Lift, discussed any equipment options, and identified that the customer would still need decals and other parts to repair his control box. Our Customer Support Specialist suggested that they purchase a new control box instead, and offered our FREE shipping option for orders over $500 saving the customer time on the repair and keeping their equipment safe.
