This sounds very much like my job, except for the nights out so I have a few bits of advice.
Try and load all the plant yourself, find out how to start it and basic operation whilst it’s on the ground. You can’t fall off the ground, whereas if you experience a new bit of kit for the first time when you have to unload it you can easily get in a muddle that will at best scare the hell out of you and at worst do untold damage or injury.
Take your time, ask questions and watch other people doing the job. Look at other trucks carrying similar items to see how well or badly they have loaded and secured and work your system from that.
There is a lot more to the job than just driving, you need to be a problem solver and ingenious. You might find sites are reasonably helpful when delivering although there will always be concrete or muck away coming so you’ll better hurry. Collecting is a different matter, they finished with the plant and left it in any sort of state with buckets / attachments scattered far and wide and bits hanging off.
This is where you need to have a few odd bits and pieces that will enable you to get it loaded rather than try and rustle up help or call for assistance.
Selection on basic tools, couple of screwdrivers, hammer, selection of spanners and a socket set will be ideal. Ideally you want a set of 6m long heavy duty jump leads so you can jump start things off the truck (having used your tools to access the battery)
Cable ties, Gaffer tape and wd40 are handy. Also beg, borrow or steal any plant keys you can, most stuff uses a generic key for the brand and security is anything from none existent to a code you input. There some with separate fobs or coded keys so you are stumped but with the more basic stuff you can at least load if the keys are missing / lost or someone is bringing them down to you.
Get a diary and write down the codes to the machines you move. If you know that ■■ plant’s digger number e76 has code 12345 write it down as sooner or later you’ll need to collect it and no one will know it. Also phone numbers are worth keeping as never given when you need them.
Once you’ve loaded keep your straps and chains in good order and try and squirrel away a couple of spare straps for emergencies. I never use the spares to secure the load, they are just in case one breaks or if something moves (something will sooner or later) or starts flapping about.
It’s a hard and dirty job that gets easier by time doing it, I’ve been doing it nearly 16 years and still learning new things. If you can last a year dealing with everything the world can chuck at you, you’ll probably not look back. I’m not sure I’d be very interested in doing a job that was just driving a truck now.
