Lorry crane (truck mounted crane) integrates cargo transportation and lifting work. Improper operation easily causes tipping, boom bending, hydraulic failure and falling cargo accidents. These standardized safety rules are for drivers, operators and fleet managers in Africa, Middle East and other overseas construction, mining and infrastructure sites, to reduce safety risks and extend the service life of your SITRAK, HOWO, SHACMAN lorry crane.https://www.hjtrailer.com/construction-machinery/truck-mounted-crane/howo-truck-mounted-straight-arm-crane.html
✅ Pre-operation inspection before lifting
Check the chassis brake system, tire pressure and outriggers for deformation and oil leakage. Inspect the hydraulic pump, oil pipe, cylinder, lifting hook, wire rope and safety latch. Test boom retraction, rotation and lifting function without load first. Check the ground condition; soft ground must add supporting base plates to prevent sinking.
✅ Standard outrigger operation
Park the lorry crane on flat and solid ground. Never work on sloped ground. Fully extend all outriggers and adjust the vehicle to horizontal level. Do not start lifting if any outrigger is suspended or not fully supported.
✅ Load and lifting range control
Strictly follow the crane load chart. Do not overload, over-range or side-lift. Do not lift buried goods or goods pressed by other heavy objects. Avoid sudden start, sudden stop, fast rotation and sharp swing of the load.
✅ Rules during lifting operation
Keep the lifting load vertically above the hook; slant pulling is forbidden. No people stand under the boom and suspended cargo. Slow down the boom movement when approaching the rated load limit. Do not use the lorry crane to drag or pull goods horizontally.
✅ Environment restriction
Stop lifting work in heavy rain, strong wind, fog and thunderstorm weather. Low visibility and strong wind will greatly increase tipping risk. Keep away from high-voltage power lines, maintain safe distance.
✅ Driving rules after lifting
Retract the boom, put away the hook and fix all accessories before driving. Do not drive with suspended cargo. Avoid sharp turning and high speed on rough roads after crane operation.
✅ Daily maintenance and operator requirement
Operators must receive professional training and master hydraulic fault emergency handling. Regularly lubricate the rotation bearing and check wire rope wear. Stop operation immediately once abnormal noise, oil leakage or shaking appears. Following these safety rules can effectively avoid rollover accidents and reduce maintenance costs. We supply LHD and RHD truck mounted cranes for overseas engineering fleets, and provide complete spare parts support.
