For high-reach equipment, a properly designed hose carrier helps keep hydraulic lines organized and protected throughout the boom's range of motion, supporting hydraulic system reliability, easier maintenance, and longer hose service life.
For most service businesses, facility management operations, and heavy contractors, the more critical question is: “Which mobile elevating work platform (MEWP) fits the way our team actually works every single day?”
Towable boom lifts for tree work provide arborists and landscaping professionals with a flexible, efficient, and safer solution for elevated tree maintenance. With compact designs, fast setup, and excellent maneuverability, towable boom lifts help tree care companies complete more jobs with less downtime.
As largest model in the GLT LIFTS towable boom lift rang, the GTB66 is built for higher reach and greater working envelopes. It is engineered for large-scale buildings and demanding outdoor sites where standard lifts fall short.
60–66 ft towable boom lifts are commonly used for high-access applications where contractors need vertical height and flexible positioning.
Typical applications include:
1. Commercial building maintenance
2. Exterior construction work
3. Sign installation
4. Electrical and lighting maintenance
5. Tree trimming and arborist work
6. Facility maintenance
7. Industrial equipment inspection
8. Rental fleet operations
Articulating towable boom lifts are especially useful when operators need up-and-over clearance around obstacles.
Yes. The unit is designed for trailer towing and can be transported by a properly rated pickup truck or other suitable towing vehicle. The towing vehicle, hitch, and towing equipment must meet the applicable weight and towing requirements.
Yes, but proper safety measures must be taken. When deploying a towable boom lift on unpaved or soft surfaces—such as grass or mud—we strongly recommend placing heavy-duty Outrigger Pads beneath each stabilizer. This maximizes load distribution, drastically reduces ground bearing pressure, and effectively prevents stabilizer sinking or tipping hazards.
The Optimal Solution for Challenging Terrain:If your jobsites frequently involve muddy, soft, or rugged terrain, we highly recommend upgrading to a Crawler Spider Lift (such as our GCA66 series), which features rubber tracks designed for superior off-road stability and low ground pressure.
The towable boom lift comes with a 1-year full-machine warranty. During the warranty period, GLT LIFTS provides free replacement parts, remote technical guidance from professional engineers, and localized service through its spare parts network to help minimize downtime.
