Bucket Truck & Aerial Device Repair

Mondak Equipment repairs and troubleshoots bucket trucks and vehicle-mounted aerial devices, including insulated and non-insulated equipment.

Device or Truck

Repair for Insulated & Non-Insulated Vehicle-Mounted Aerials

When a bucket truck has a problem, the issue may be in the aerial device, or in the truck and hydraulic systems supporting it.

Sometimes the problem is obvious. Other times a boom function is slow, the upper controls quit working, an outrigger will not operate, the unit has an intermittent electrical problem, or the machine simply does not work the way it should.

We work through the hydraulic, mechanical, electrical, and control systems to determine what needs attention.

Makes We See

Brands We Work On

Mondak works on aerial equipment from manufacturers including:

  • Altec
  • Terex / Hi-Ranger
  • Versalift
  • Elliott
  • Dur-A-Lift
  • and others

This includes equipment such as:

  • Overcenter aerial devices
  • Non-overcenter aerial devices
  • Telescopic aerials
  • Articulating aerials
  • Insulated bucket trucks
  • Non-insulated aerial equipment
  • Truck-mounted man baskets

If your make or model is not listed, give us the manufacturer, model, and what the equipment is doing.

Across the Machine

Aerial Device Repair

Mondak can repair and troubleshoot problems involving:

The boom may be where the problem shows up, but the source can be somewhere else on the machine.

Same Symptom, Several Causes

Hydraulic System Problems

Bucket trucks rely heavily on hydraulics, and a number of different problems can create the same symptom.

Mondak can work on:

A slow boom does not automatically mean the pump is bad.

Internal leakage, a valve problem, restriction, mechanical binding, or another condition can create similar symptoms.

It Adds Up

Mechanical Wear

Vehicle-mounted aerial equipment sees repeated loading and movement throughout its working life.

Wear can develop in:

  • Pins and bushings
  • Bearings
  • Pivot points
  • Rotation systems
  • Outriggers
  • Boom components
  • Cylinder mounts
  • Platform leveling components
  • Structural connections

A small amount of wear in several areas can add up to excessive movement or poor operation.

Mondak can inspect and repair the mechanical side instead of trying to compensate for worn components with hydraulic adjustments.

Platform and Ground

Upper & Lower Controls

Aerial devices need reliable control from both the platform and the ground.

Mondak can troubleshoot:

  • Upper controls
  • Lower controls
  • Joysticks
  • Switches
  • Solenoids
  • Sensors
  • Wiring
  • Connectors
  • Relays
  • Interlocks
  • Control modules
  • Communication problems

If a function works from one control station but not the other, that gives us a good place to start.

Sometimes the hydraulic system is ready to work, but the command never reaches it.

Before the Oil Reaches the Boom

PTO, Pump & Truck Systems

The aerial device depends on the truck underneath it.

Depending on the equipment, Mondak can work on:

If the aerial unit is losing hydraulic performance, the problem may start before the oil ever reaches the boom.

Insulated Equipment

Insulated Aerial Devices

Mondak also works on insulated bucket trucks and aerial devices.

On this equipment, the condition of the boom and insulating components matters beyond normal hydraulic and mechanical operation.

Mondak can help with:

  • Insulated aerial repair
  • Hydraulic leaks around insulated sections
  • Controls and electrical systems
  • Mechanical repairs
  • Structural concerns
Finding the Part

Sometimes You Already Know What Failed

Not every bucket truck repair starts with troubleshooting.

You may already know what broke.

The problem may be that the part is obsolete, hard to find, or no one wants to work on an older machine.

Depending on the repair, Mondak can look at options such as:

If the equipment is worth repairing, we are willing to look at practical ways to keep it working.

One Company

Inspection & Repair in One Place

Mondak also provides annual aerial inspections.

If an inspection identifies:

  • Excessive pin or bushing wear
  • Hydraulic leaks
  • Damaged hoses
  • Bearing wear
  • Electrical problems
  • Control problems
  • Structural concerns
  • Other repair needs

we can help address those findings.

The inspection and the repair do not have to become two separate projects with two different companies.

Field and Shop

Field & Shop Repair

Many bucket truck repairs can be handled in the field.

More extensive mechanical work, cylinder repair, machining, fabrication, structural repair, or major teardown may make more sense in the Mondak shop.

We can help determine the practical approach based on the equipment and the repair.

Bucket Truck & Aerial Device Repair
