Working with a partner or team can also enhance safety measures during installation by providing additional support in case of an emergency or accident. Having someone else present can also help identify potential hazards that may have been overlooked otherwise.

Assembly and Installation Process

Safety Arm Installation and Use

Safety should always be the top priority. One important component of the power hoist is the safety arm, which must be installed correctly and used properly to ensure safe operation.

To install the safety arm, first, make sure that the body of the trailer is unloaded. Then, raise the trailer body to a sufficient height and shut off the hydraulic power to the hoist. Grasp the safety arm and rotate it into an up/vertical position. Once you have accomplished this position, push down on the arm until it is in its support bracket at the base.

Next, slowly lower both the hoist and body until they contact with each other. It's crucial to take your time during this step as rushing can lead to accidents or damage to equipment. Once you've lowered everything safely, reverse these steps to place the arm back in its hanger for transport.

Assembling The Power Hoist

Another essential part of assembling a power hoist is installing its hinge correctly. To do so, mount hinge so that its pad is level with your trailer frame. Center hinge on support and weld it securely at all contact surfaces.

Installing The Power Hoist

Once you've assembled all components of your power hoist successfully, it's time for installation onto a secure beam or support structure. Be sure first to check M dimension specifications (see hoist dimension and capacity pages on pg 24-40) before centering your hoist assembly on your trailer frame.

You'll also need to align your lower pivot centerline with manufacturer specifications based on your specific model:

  • PH310: 27"

  • PH416: 38"

  • PH516: 38"

  • PH520: 46"

  • PH616: 38"

  • PH620: 47"

  • PH621: 46"

  • PH625: 52"

  • PH630: 60"

It's essential to ensure proper alignment and stability during installation. To do so, weld or bolt a plate to tilt the frame and supports to the cross member. Doing this will help prevent any accidents or damage that may occur due to misalignment.

Dump Trailer Power Hoist

The angle of the dump is an important factor in determining how much weight the hoist can lift. The higher the angle of the dump, the less weight a hoist can lift safely.

For example, if you have a dump trailer with a 45-degree dump angle, your power hoist may be able to lift up to 10 tons safely. However, if your dump angle is only 30 degrees, your power hoist may only be able to lift up to 5 tons safely.

It's crucial always to check manufacturer specifications for your specific model of power hoist and dump trailer before operating them together. Doing so will help ensure that you're using both pieces of equipment correctly and safely.
