8. Safety rules

LOOK AROUND BEFORE MANEUVERING THE CRANE

Look around before maneuvering the crane. The situation at your work area may have changed after you checked the area in advance.

PAY ATTENTION TO PEOPLE

Never operate the crane over people, with or without load in the hook.

STAY ALERT

Do not allow people or equipment to stay in the area below or around hanging loads.

MAKE SURE THAT THE ROAD IS CLEAR BEFORE BACKING UP

Never reverse the vehicle before you are completely sure that the area behind the machine is free from obstacles and/or people.

THE SAFETY SYSTEM MUST NOT BE TURNED OFF

Overload protection and safety equipment shall stop dangerous crane movements and warn ahead so that the crane is not exposed to overload.

STAY ALERT WHEN YOU DRIVE

Pay attention to obstacles while driving. Do not take a chance when driving towards an obstacle that is above you or by the side of the road. When driving in crowded areas, be sure to have an assistant help you to avoid collisions and damage to the machine and/or surrounding objects.

LOCK THE SWING BEFORE MOVING THE CRANE

Always lock the swing on the crane before moving the vehicle.

SECURING CARGO

Secure the load so that it does not move or fall off during transportation. It must at least withstand the following:

  • Forward: Total load weight.
  • Rear: Half load weight.
  • Side end: Half load weight.

BEWARE OF HIGH VOLTAGE CABLES

High voltage:
Contact the coordinator at the workplace to
do a SJA for machine protection assessment
(earthing) if there is a theoretical risk of
getting in contact with high voltage cables.

Low voltage: (under 1000 volts)
The safety distance is 2.5 meters.
SJA should always be used when working
near electrical wiring.

DO NOT MISHANDLE THE BOOM

Never pull or push cargo with a boom. Never use the boom to pull sideways. Cranes are not designed for lateral loading.

.

CORRECT USE OF SLINGS

Use sufficient number of wire pairs on the hook block when doing heavy lifting and ensure that all straps are properly attached. In order to achieve maximum lifting capacity, the lifting block should be equipped with sufficient number of wire pairs. When using a hookswitch with multi- threaded castors, there should be at least three turns left on winch drum.

When using straps, ropes and hooks, etc., ensure that they are properly attached and secured for lifting or lowering the load.

.

KEEP THE EQUIPMENT CLEAN – FOLLOW THE INSTRUCTION MANUAL

Follow all instructions in the manual and signs on the site. Find out what they mean and follow the order.

KEEP THE FLOOR CLEAN

Keep the shoes clean. Before entering the operator compartment, wipe away any dirt or grease from the shoes. This reduces the risk that the foot slides on the pedals which could result in an accident.

ALWAYS HAVE THE LOAD UNDER CONTROLL

Check all brake and/or locking devices before using the crane. Perform a brake control (wheel and turn) and inspect all locking devices on wires, straps, etc. before starting a work or relocation operation.

NEVER HANDLE MORE THAN ONE LOAD AT A TIME

Just lift one load at a time. Do not lift two or more separate strap loads at the same time, even if the weight of the total load does not exceed the machine’s capacity.

FIND OUT THE WEIGHT LIMIT OF A BRIDGE

Check the maximum permissible weight load on bridges. Before using the bridge, check if it can withstand a load greater than the weight of the machine.

USE FULLY EXTENDED SUPPORT LEGS AND USE SAFETY LOCK

The main rule is to use fully extended support legs. Follow the instructions in the manual in case of exceptions (for example, VarioBase).

MAKE SURE TO HAVE A SOLID SUPPORT BEFORE STARTING A LIFT OPERATION

Check the machine’s stability before lifting the load. Make sure that the support legs (or wheels when lifted on wheels) are safely placed on a solid surface, that the machine is in upright position, brakes are in use and the load is securely fastened and attached to the hook. Lift the load slightly from the ground and check the stability again before the lift continues.

HANDS CAN BEND STEEL

Do not exceed the capacity of the machine. Do not trust the machine’s tilt stability to determine maximum lifting capacity. Do not exceed the listed capacity that’s written in the lifting chart, including weight loss for lifting equipment (block, ball, hoist hook, jib, etc.).

KEEP THE BOOM CONFIGURATION AS SHORT AS POSSIBLE

Use a boom configuration as short as possible. Swiveling loads in a long wire can cause unstable conditions and possible structural damage to the boom.

NEVER ALLOW ANYONE TO HITCHHIKE

Never allow anyone to ride the load, hooks, straps, etc.

DISCONNECT THE LOAD ON THE GROUND BEFORE LEAVING THE CONTROL PANEL

Never leave the machine with load hanging in the hook. Never leave the machine with a lifted load, and if the machine is left, the load must be lowered to the ground and the engine must be switched off before leaving the vehicle.

ENTER/EXIT THE VECHILE ONLY WHEN THE MACHINE OPERATION IS PAUSED

Never step on and off a moving machine. When you have to enter or exit the vehicle, hold on with both hands and ensure a stable foot grip.

SIGNALS AND SIGNS

Get familiar with the signals. Standard hand and radio signals can save lives and load, see “CRANE SIGNAL SCHEME
