    50mm ball towhitch, jockey wheel and overrun DESCRIPTION braking system with handbrake. The TL33 is a two-stage articulating boom lift platform, Four ‘Quick set’ fold down outriggers with screw jacks for designed to raise two operators with hand tools to a work level adjustment are provided.

  • Page 7: Purpose And Limitations

    Purpose and limitations The purpose of the TL33 work platform is to provide a quickly deployable, trailer mounted, variable height work platform. It is capable of lifting two people with work tools up to an upper limit of 215kg in total. The unit will provide the ability to reach over obstacles and may be used on uneven firm ground provided the chassis is correctly levelled using the screw jack adjusters prior to elevating.
