RAM’s AML Personnel Hoist, Load-Limited by design

RAM’s AML load-limited personnel rated air hoist is built to meet or exceed any known global regulatory or independent, third party design standards governing this class of personnel hoist.

By using 35 years of experience manufacturing personnel hoists for Drilling applications, RAM elected to stay with the most basic principles of power transmission and design that allows the AML’s unique configuration and takes a very simple approach to a complex application.

By regulating the inlet air pressure reaching the motor’s piston head, the output torque generated by the drive train, then rotates the large 24 inch diameter drum that stores 100% of the active or traveling rope on a single layer, which in turn provides constant and precise delivery of both torque & speed throughout the lifting cycle, a claim no other hoist available on the market today can provide.  In essence, the specific inlet air pressure produces a limited amount of output torque without requiring complex pressure sensing valves, or other devices to ensure the operator total control over any force the hoist can impart onto the “Rider” at any point in the lifting cycle.

The AML’s powered levelwind can handle fleet angle loads up to 6 degrees and wire rope take off angles ranging up 7 degrees from the “0”, 45 or 90 degree intended take off angles.

The AML’s simple drive train and load brake arrangement does not require an auxiliary source of compressed gas to provide emergency “power-off” load lowering performance making this process quick, fast and easy to use under stressful emergency conditions.

All AML’s are built to allow for use in cold weather / low temperature applications of -20 degrees “C” at no extra cost.

RAM Optional Documentation:

  • RAM “In-House” Level III-Data Book including material traceability certificates for all load bearing components and all applicable NDT reports.
Specifications:  Performance is based on 90 psi (6.3 bar) air inlet pressure with motor running
