ARI-HETRA Heavy Duty Mobile Lift (HDML) system.

The Heavy Duty Mobile Lift (HDML) system is the heart of the ARI-HETRA product line. No other system matches it for safety, flexibility, and ease-of-use. The HDML system is available in configurations of 4, 6, or 8 posts with lifting capacities from 12,000 to 40,000 pounds per post. Whether you need a bus lift or truck lift, there is an HDML system for your needs.

Since the HDML system is mobile, there is no installation. All that is needed is a flat, stable floor and a power source. This means that the system can be used inside or outside.

The HDML system's controls are top-mounted on each post with up/down buttons and emergency stop buttons. The mobile column lift can be operated from any one of the control boxes. There is no dedicated master post.

The top-mounted gearbox, motor assembly and double-acting disc brake are housed in a watertight aluminum extrusion. Lifting is achieved through a hardened, ball bearing screw-nut assembly suspended from the top of the column. The expected life of this screw is ten times greater than that of an acme thread.

Security devices are built into the electrical system, which stop the mobile lift from operating in case of electrical failure or overload. The main control box has an electrical phase sequence relay, which automatically checks the rotation of the motors and adjusts it accordingly. In addition, if one phase is cut off, the system will stop automatically.

The slim design allows optimum visibility, which is especially important for maneuvering and positioning.
